At present

biomass direct combustion technology

there are many deficiencies

resulting in a large number of biomass fuels are not well utilized. High-low bed better achieve lower furnace combustion of biomass fuel vapor

and ensure the stability of fuel combustion. High-low bed has fuel adaptability and high combustion efficiency. High-low bed solved now grate boiler and ordinary fluidized bed boiler burning biomass is insufficient

there is a very good market prospects.
