DZH type active grate coal steam boiler has a wide range of fuel sources. It is a renewable green energy source. It contains almost no sulfur and less ash. Its growth process can absorb all the CO2 generated by the combustion process and achieve zero CO2 emission. Biomass energy will gradually replace coal and become one of the main energy sources. Biomass fuels include straw, wood shoots, bamboo wood processing waste, grain shell skin, fruit shells, sugar residue, oil residue, and so on.Compared with coal-fired boilers, biomass fuels are less expensive and significantly reduce operating costs.
