As the fuel size varies according to different biomass materials and have different combustion properties, some of the biomass fuels have to adopt reciprocating grate combustion for better effect, such as fire wood, woodchip, other big size biomass materials, as well as mixing with coal.
We make and supply this series of boilers with steam capacity from 4t/hr to 35t/hr.
