Biomass and coal fired boiler can be divided into single-drum solid fuel boiler and double drum solid fuel boiler according to the boiler structure. We select the different grates to suit for the different fuel characteristics, such as fixed grate, light chain grate , reciprocating grate and other types of grate. Equipped with different auxiliary devices, the boiler has better adaptability to fuels as following :
Fuel :Biomass pellets, Biomass briquettes, Wood chip, Sawdust, Bagasse, Rice husk, Palm fiber and palm shell, Coal pellets, etc.
Feeding way Lifting type: Scraper type, Screw type, etc.
