Since January 2018, we have been working intensively on the development and production of a 300 kW boiler for the legal combustion of particleboard and carpentry residues and remnants from furniture production.
The boiler will be certified in emission class 5 for wood pellets and meet EcoDesign requirements.
Further certification will be a mixture of wood pellets and non-wood biomass in class 4 (plant pellets, agro-pellets, grains, rape residues, mustard and other similar materials). When using flue gas filters, the boiler will meet the requirements of emission class 5.
The MultiBio 300 is an automatic hot water boiler for combustion of chipboard fibreboard and carpentry shreded waste if it is operated at the place where this fuel is produced. The boiler is a Czech product suitable for comfortable automated, environmental and production halls of 90 to 350 kW joinery. The boiler can be operated both with and without a storage tank due to power modulation. The boiler can also be used to produce hot water up to 100° C.
The MultiBio burner is a product with a unique combustion system that consists of a pressurized air chamber, a rotary grate with a special drilling, a precision fuel and turnstile thrust auger that completely prevents the fuel from burning back into the hopper even without using a water canister.
MultiBio is an industrially protected product with a rotating combustion chamber that allows burning both high quality wood pellets and lower quality wood pellets with high ash content or crushed chipboard, plywood, fiberboard and other glued wood. The combustion chamber of any grease and a large amount of ash rains into the ash chamber during burning and does not bother operating the boiler.
The lowest quality wood pellets and especially the bark pellets hence the high percentage of sintered ash can not be reliably burned in the burners of simple bowl or retort structures.
MultiBio differs fundamentally from its unique design from other products on the market. The MultiBio boiler body is three-stroke. In small dimensions, it has a high efficiency and a low exhaust temperature, which it maintains even if the boiler operator is cleaning the heat exchanger once only during the heating season. Unlike single stroke boilers, there is a significantly better heat exchange between the fire and the heated water in the MultiBio boiler.
The MultiBio hot water boiler has precisely controlled air and fuel metering for the full range of its power with a working temperature within the burner up to 1200 ° C. The high combustion temperature ensures low emissions without odor and aggressive compounds. MultiBio does not use a damping mode in which fuel is still smolder. Thanks to this combustion the boiler does not suffer from self-destruction and does not bother the surroundings by smell from the chimney. The MultiBio boiler has negligible emissions of carbon monoxide and is environmentally friendly. With the MultiBio boiler, you can actually melt for free if you have your own chipboard.
MultiBio pellet boiler control is intuitive and easy. Complete electronics and software is an original Czech product developed only for MultBio boilers.

MultiBio Burners are able to burn fuel with difficulty combustible due to their construction, such as plant pellets.
MultiBio boilers are multi-fuel. These boilers excel in burning a wide variety of pellets, both wood and plant and their mixtures.
The advantage of combustion of plant pellets lies above all in their price. The price of vegetable pellets is up to half the price of wood pellets. MultiBio pellet boilers can also cope with the combustion of plant pellets made from highly sintered materials such as grain straw or hay thanks to MultiBio unique internal design.
Our customers often ask what are the advantages of a MultiBio rotary burner against bowl burners or square universal burners in connection with the burning of wood pellets. At first glance, it would seem that wood pellets can burn all types of burners on the market. MultiBio burners can also burn pellets whose quality does not match the certificate issued by the dealer to pellets. This is often the case and the pellet dealer can hardly prevent or influence it.
The primary advantage of the burner is that it is not susceptible to the quality of wood pellets and can burn even the lowest grade pellets that burn ash ash or even pellets that may contain more minerals and a significant amount of ash or admixtures that can make pellets easier for their producers production.
From experience, we know that even if you bought high quality pellets with a certificate, you may find that you have a batch that did not "do". Then there is a situation that you have, for example, 5 tons of pellets in the basement, which the "normal" burner can not burn. Even if the dealer of the poor pellet willingly exchanges, it is necessary to move them out of the cellar or suffer removing excessive ash, or clinkers from the burner and re-burn the burner. The MultiBio boiler does not do this. It can reliably burn pellets with which the normal burners or torch burners can not burn.
