Pellets and Other Fuels

Shelf Full of TidyFire™ Products

Undeniably testified by independent research, TidyFire™ charge burners are clean and effective with many fuels, including:

  • pellets and biocoal
  • charcoal and briquettes
  • wood chips and biochar

You get a full charge of wood pellets for the smallest burner typically for about 50¢ and for the largest burner for about 3€ from department stores, hardware stores and supermarkets - conveniently in bags of 15-20kg. Suitable alternative pellet fuels include corn / maize straw pellets and canola / rapeseed straw and hull pellets among others.

Charcoal burns with smooth and even glow in TidyFire™ burners producing very little ash. Try it out and you'll be amazed how big a difference a TidyFire™ burner makes.

Unrivalled Combustion Technology

Both the cylinder combustion method of bioBlaze models and the container incineration method of bioHeart models are patented. Combustion is complete from the beginning till the end. What's left of wood pellets is only a little white ash consisting of non-combustible minerals and trace elements.

Competing products are not proper pellet/biomass charge burners, but pellet baskets and grates. Significant part of the energy remains unused with these pellet baskets and grates. Combustion is nowhere near smoke-free and the flue gas produced is highly unhealthy. Much of the pellet remains unburned and the time the dying embers glow is particularly long. Brown ash and black carbon remain as a result of incomplete combustion.

Heat Cleanly and Effectively with Pellets Always - or when you Run out of Firewood

Effortless, Affordable & Healthy

Spend your summer evenings for example at the end of a pier with a smoke-free and quiet, but warm and lively fire.

Wilderness

The bioBlaze 10 kWh model is best suited for use in the wild. The burner is comfortable to carry, as its own weight is only 1.3 kg / 2.8 lb, and 3.4 kg / 7.4 lb with a full charge. Unlike with gas burners, there's enough power for warming up in addition to cooking. Use is permitted in many places since it's not an open fire. Be sure however to use the burner on a non-combustible surface and to safely empty it from still burning embers before continuing the journey. Look for a suitably sheltered place in windy conditions, for example, behind a large stone under the wind. Alternatively, you can use a folding windscreen like the ones used with gas burners.

Biopellets - Pelletized Biomass

Tidy Living Space

Handling of biopellets is a lot more tidy and living-space-friendly than working with firewood or wood chips. Biopellets are practically litter-free, especially when handled with TidyFire accessories. This is only one of the reasons why biopellets are a preferable type of fuel for regular heating during the cold season.

Small Stogare Space and Ease of Storage

Storage space needed for pellets is always less than half of that required for firewood. This is because there is typically 2.8-4.6 times more energy in a cubic meter of biopellets (2900-3400 kWh) than in one cubic meter pile of firewood (740-1040 kWh @ 20% moisture). Firewood can be organized into neat stacks to reduce the required space, but it still needs about 2.5 times more space than wood pellets containing the same amount of energy. Pellets need no organization as they are typically bought in bags or delivered in sacks. Large quantities can be blown from a tanker directly to a purpose-built container or storage facility.

Ensure Cleanliness and Efficiency of Combustion

Pellets burn extremely clean due to their extra low moisture content. Moreover, commercial quality pellets use only purified raw materials.

Wood Pellets

Cheap Heat

Wood pellets are highly affordable throughout the world and provide heat at a fraction of the cost of electricity. For example in Europe, wood pellets are typically much cheaper than firewood, roughly three times cheaper than oil, and many times cheaper than electricity in terms of heating value.

Utmost Efficiency and Cleanliness

Wood pellets burn extremely efficiently and clean in TidyFire burners because of their purified raw material and extra-low moisture content. Commercial quality wood pellets don't contain bark, which has a high ash content and low heating value. Bark is also known to cause both small (sub-µm) and large (~5µm) particle emissions in typical household furnaces/boilers. Moisture content in wood pellets is very low (8-10% of weight) compared to that of well-dried firewood (20% of weight in summer-dry conditions and 25% in the winter).

Very Little Ash

TidyFire burners produce very little ash with wood pellets. Ash content of wood pellets is only 0.4-0.5% of weight and this is all that remains after the complete combustion of TidyFire.

Biopellets from Crop Residue

TidyFire burners burn biopellets and briquettes made from crop residue just like wood pellets - cleanly and with extremely high efficiency. Density of such biopellets is close to that of wood pellets, while net heating value per weight is more or less at the same level.

Straw pellets result in about ten times more ash than wood pellets, while husk or hull pellets contain roughly half the ash of straw. Ash is a highly effective form of fertilizer and can be used for gardening and soil improvement.

However, high ash content brings to bear a slight drawback. Temperature of embers has to be 950-1100℃ for straw to burn efficiently and cleanly. Melting point of ash depends on its composition. Highly alkaline ash melts below the desired temprature, resulting in slag formation on the grate of the burner. The usage of some biomass qualities in their pure form is troublesome because of this, as they cannot be burnt efficiently and cleanly without the formation of slag.

Use of crop residue as biofuel is increasing. A considerable share of this use takes place in the form of straw and husk or hull pellets. Straw pellets are also called stalk pellets or stover pellets in different contexts, while it's essentially the same fuel product. The following covers some common forms of solid biofuel used in different parts of the world.

Corn/Maize Straw

Net heating value of corn straw pellets is about 4.8 kWh/kg. Ash content of corn stover is 5.2% in average - lower in cold climate and spring harvested stover and higher in warm climate and fall harvested stover, according to a Canadian study. Ash resulting from burning corn straw pellets in a TidyFire burner has a light, yellow-brown color and a powder-like consistency. Such powder-like ash is effortlessly removed with the patented TidyFire grate, simply by pulling a lever.

Canola/Rapeseed Straw and Hull

Oilseed rape straw is an excellent choice of biomass for pellet fuel. Its ash content of about 5% is highly resistant against melting, making it one of the most tidy biofuels to handle as it is unlikely to form slag under any circumstances. The residue/byproduct of making canola oil, the rapeseed hull, is however much more volatile what comes to ash content. Combustion efficiency and net heating value of rapeseed hull pellets are high due to the oily consistency. Rapeseed hull pellets are hence an interesting choice for biofuel, provided that they are not allowed to burn too hot.

Wheat Straw

Wheat straw pellets are well suited for combustion. Their ash content is on the higher side at about 6-7% in average with a lot of variation. However, the ash is much less alkaline than in many other cereals, which makes it less likely to melt and form slag on the grate of the burner. Some straw pellet producers mix wheat with other plants, such as canola/rapeseed.

Oat, Barley, and Rye Straw

Oat, Barley, and Rye straw have a 4-5% ash content, which is alkaline and likely to melt. Proper additives are needed with these cereals to fully avoid formation of slag on the grate of the burner. These additives increase production costs and raise overall ash content.

Rice Husk and Straw

Grains are traditionally dried up in rice mills with air heated up by burning rice husk - the waste product of the mill. While pelletized rice husk is a good form of biofuel, rice straw is less preferable because of its high ash content, which varies significantly around a mean figure of 18%.

Cotton Stalk

The density of cotton stalk pellets can be close to or higher than that of wood pellets. This is the main advantage of cotton stalk, while ash content ranges from 5% to 10%.

Sunflower Seed Shells

Sunflower seed shells are typically used in the processing facility like rice husk. Ash content is usual in the category of seed shells - at about 2.5%.

Firewood

There is no need to give up the option of using firewood - quite the opposite. Standalone TidyFire burners are simply removed from the fireplace to allow the use of firewood. Hybrid TidyFire burners are integrated into fireplaces to guarantee equally clean combustion of both firewood and other forms of biomass. If you are planning to hire a fireplace mason, contact us and we'll be happy to support you and your mason in realizing your new fireplace with an intagrated hybrid TidyFire burner.

Charcoal, Briquettes, and Biochar

Charcoal burns with smooth and even glow in TidyFire burners producing very little ash. The resulting even heat greatly eases cooking with charcoal, while food items stay clean in the absence of fly ash. Fly ash is a problem of conventional charcoal grills, especially notable in windy conditions. With such conventional charcoal grills the fly ash is impure due to incomplete combustion and any gust of wind is likely to pollute your food with it. Impurities of the fly ash produced by a conventional grill include organic compounds known to be carcinogenic. In contrast, the little ash produced by TidyFire burners is composed of pure, incombustible earth minerals only and includes concentrated trace elements essential for life. Such pure earth minerals in the form of ash produced by TidyFire burners are not only edible, but promote health and prevent diseases.

Charcoal briquettes and biochar are fine alternatives to charcoal. Charcoal briquettes contain binders like starch, and additives like sodium nitrate, which result in more ash than pure charcoal. Biochar briquettes are usually made from crop residue, such as straw and husk. Biochar thus results in even more ash than charcoal briquettes, since crop residue contains more ash than wood.

Biocoal

Black pellets are one emerging form of biocoal and torrefied wood pellets, produced among others by Solvay, seem to be an especially promising type. Energy density of torrefied wood pellets is 4500-5100 kWh/m3. That is roughly 1.5 times the energy density of widely available, regular wood pellets, and 4.3-6.9 times the energy density of firewood. TidyFire burners and fireplaces burn all forms of biocoal cleanly and efficiently.

Wood Chips / Chopped Biomass

Wood chips and similar coarsely chopped biomass can be used in place of pellets. They can be burnt cleanly, but produce much less heat (500-900kWh/m3) due to low density (150-350kg/m3) and generally high moisture content (varies widely). Wood chips are less tidy to handle as they contain bark and other loose impurities that easily scatter around. Chips are usually made from thinning and logging residue such as branches, tops, and stumps. Branches, tops, and coppice contain a lot of bark. Ash content of chips depends on the part(s) of wood used and is roughly 0.4% for pure barkless timber, 2% for branches and coppice, 3% for bark, and 5% for the needles of conifer trees.

Energy Crops

Crops specifically grown for energy include willow, alder, poplar, and dense grasses such as elephant grass. Energy crop pellets are notably cheaper than commercial quality wood pellets due to their lower fuel quality. Wood pellets and chips from energy crops are often made from coppice and hence include bark. Bark and the fast growth of energy crops together result in a higher ash content and lower heating value in comparison to commercial quality wood pellets. Commercial quality wood pellets are madde from processing residue of sawn timber and other refined wood products. Species typically used for refined wood products grow a lot slower than the woody energy crops.

Smokeless Combustion is Guaranteed by Patented Methods

Wouldn't you rather enjoy live fire through a clean and clear glass than watch it accumulate soot hiding the flames? TidyFire burners and fireplaces are practically free from soot and smoke production, helping you keep your hearth warm, home tidy, and surroundings healthy. TidyFire burners use a patented method that effectively forges combustion of solid fuels to guarantee smokeless and particle-free fire even with high moisture content in the fuel.

Problems of Smoky Fire

Heat production with conventional fireplaces and their smoky fire lightens your wallet, harms your health, and bears a negative impact on your surroundings. Moisture content of freshly cut wood is approximately 40-60% of its weight, while well dried firewood has 20-25%. This moisture has to evaporate when the firewood burns. Evaporation takes energy and cools down the fire. Relatively cold fire burns incompletely, producing smoke and soot. Soot effectively insulates the produced heat from the structures of the fireplace and the chimney. Furthermore, vapour expanding in the heat of fire significantly increases the volume of flue gas and thereby speeds up its flow. Accelerated flow shortens the effective heat transfer time as hot flue gas is prematurely forced out of the fireplace and chimney.

Conventional fireplaces and not-so-dry fuels thus produce a multifaceted set of problems tangled together.

  • Energy is wasted,
  • fireplace and chimney get stained,
  • health-harming emissions are produced, and
  • heat transfer is inhibited.

Notable portion of heat is left unreleased to the surroundings as energy is used up for evaporating moisture. Combustion is incomplete in cold fire and soot accumulates in the fireplace - especially on relatively cold surfaces such as glass doors. Further unreleased energy leaves the chimney in the form of health-harming particles and smoke forced out by the expanding vapour. Fast flow of flue gas and produced soot inhibit the transfer of heat to the fireplace and chimney structures.

Effective Heat Transfer

Clean combustion and slow flow of extra hot flue gas together ensure effective heat transfer not only from visible flames, but also from dying embers. Substantially more heat is accumulated to the fireplace and chimney structures during an extended period of efficient heat transfer and cooled down flue gas slowly leaves the chimney.

Heat is transferred most efficiently to clean structures, that is, in the absence of a heat insulating layer of soot. Clean combustion of TidyFire burners brings about effortless maintenance of a soot-free fireplace and chimney.

Compared to firewood, TidyFire burners produce a significantly lower volume of hotter flue gas. The higher temperature provides a substantial improvement of heat transfer efficiency, while the lower volume generates a slower flow and enables an extended heat transfer period.

Health Appreciating Choice

TidyFire burners produce practically no smoke or particle emissions. Smoke and particle emissions are carcinogenic and harmful to the health of people in the vicinity - not least to whoever looks after the fire. By adopting TidyFire, you show your appreciation of loved ones, people around you, yourself and your health, as well as nature. Net carbon footprint of all TidyFire fuels is zero, while for example, 1 m3 (220 imperial gallons) of oil produces 2,660 kg (5,864 lb) of CO2 emissions.

Charcoal burns with smooth and even glow in TidyFire burners producing very little ash. The resulting even heat greatly eases cooking with charcoal, while food items stay clean in the absence of fly ash. Fly ash is a problem of conventional charcoal grills, especially notable in windy conditions. With conventional charcoal grills the fly ash is impure due to incomplete combustion and any gust of wind is likely to pollute your food with it. Impurities of the fly ash produced by a conventional grill include organic compounds known to be carcinogenic. In contrast, the little ash produced by TidyFire burners is composed of pure, incombustible earth minerals only and includes concentrated trace elements essential for life. Pure earth minerals in the form of ash produced by TidyFire burners are not only edible, but promote health and prevent diseases. For example birch tree ash has been used especially for medicinal purposes in Finland throughout the history.

Easy to Use

All TidyFire burners are designed to be easily refilled, lit up, and emptied of the little ash produced (only incombustible earth minerals remain as a result of complete combustion). Cleaning the burner is easy - we recommend only an occasional rinse with water. Burning time for a full load is approximately 1-3 hours, depending on the model of the burner and air supply. Embers will stay hot for a couple more hours after visible flames have died out. Fuel should never be added on top of hot embers, but only when the burner has cooled down sufficiently.

Cheap to Own

TidyFire burners are built to last using first-class materials together with the highest level of craftmanship. Your TidyFire burner can last up up to a lifetime - depending on use.
