There is then a fuel feed delivery system which connects the biomass boiler to the fuel store, and when there is a demand for heat the fuel is automatically conveyed to the boiler for combustion. Once in the combustion chamber the boiler works in a different way to an open fire, where a process called gasification takes place.
The most common type of biomass boiler is based on a grate to support a bed of fuel and to mix a controlled amount of combustion air, which often enters from beneath the grate. Biomass fuel is added at one end of the grate and is burned in a fuel bed which moves progressively down the grate, either via gravity or with mechanical assistance, to

With Valmet BFB Boiler, you can count on high combustion efficiency of over 99%, resulting in boiler efficiency typically around 90% even with high moisture fuels. For renewable biomass fuels. One of the advantages of the boiler is the possibility to use fuels with high moisture content and low heat value.
The combustion process is largely affected by moisture content of the fuel. A biomass with high moisture content is not suitable for direct combustion. In order to sustain the combustion in a boiler, biomass is often burnt at a moisture level below 55 – 65 wt% while the optimum moisture content could be as low as 10 – 15 wt% (Ross, 2008
The residual heat from a biomass unit varies greatly depending on the boiler design and the thermal mass of the combustion chamber. Light weight, fast response boilers require only 10L/kW, while industrial wet wood units with very high thermal mass require 40L/kW.
The resulting objectives of a modern biomass stoker combustion system include: maintaining an efficient, stable combustion process while supplying the desired boiler heat input with low emissions.
Feb 24, 2017 · Therefore, thousands of biomass pellet plants has been establish in recent years, and a wide range of biomass pellet combustion equipment have been developed since then, such as pellet grill, pellet stove, industrial pellet boiler and so on. The structure of normal coal boiler does not suitable for biomass pellet combustion.
Since biomass consists of “recently alive” material, burning biomass is CO 2-neutral in the sense that it only releases the quantity of CO 2 that the plant absorbed during growth. Some biomass needs pre-treatment before the fuel is fed onto a combustion grate where it is burned. The heat from the combustion is used to fire the boiler, which

A boiler utilizing a standard burner with a 4:1 turndown can cycle as frequently as 12 times per hour or 288 times a day because the boiler must begin to cycle at inputs below 25% capacity. With each cycle, pre- and post-purge air flow removes heat from the boiler and sends it out the stack.
A biomass boiler might simply be too big for your home, but smaller standalone wood burning stoves are also available, which are normally used to heat one room by burning logs or waste wood. These wood burning stoves can be fitted with a back boiler that uses the heat produced when the wood is combusted to heat water, that can then be used for
Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
