Boiler Infeed

The challenge

The cost of producing energy from biomass is very dependent on efficient handling of the various types of biomass available and the efficiency of each process. Biomass needs to be distributed uniformly to the different feeding points in a boiler or gasifier so that capacity and combustion can be optimized, and emissions can be minimized.
