Biomass feeding systems for boilers and gasifiers
Proven and efficient biomass solutions
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.
ANDRITZ has complete solutions for feeding biomass materials to boilers and gasifiers. The scope of supply can vary from complete plants to individual equipment delivery. ANDRITZ has a depth of experience in project management, ensuring reliable deliveries and excellent economic results for customers.
