What is the difference between a biomass boiler and a coal-fired boiler


First of all, the fuel is distinguished. A boiler that uses biomass energy as a fuel is called a biomass boiler. The particle emissions of biomass boilers and coal-fired boilers were compared, and two boilers with different structures were tested and analyzed. The biomass boilers used straw and wood. Boilers that use coal and carbon as fuel are called coal-fired boilers. Under a number of environmental protection policies for boiler management, traditional coal-fired boilers have completely withdrawn from the stage. Only boilers with more than 10 tons of dust must meet national environmental protection requirements (dust, sulfur, and nitrate emissions).

From the structural point of view, because of its lower calorific value, biomass boiler fuel has a larger loading capacity than coal, the furnace design is larger than coal-fired boilers, and the furnace arch is higher. Generally, it is equipped with secondary blast, so that biomass pellet fuel can be sufficient. Combustion to obtain higher calorific value and improve thermal efficiency.

In terms of fuel use, biomass boilers can not only burn biomass fuels, but also adapt to coal, while coal-fired boilers only burn coal.
