Combustion Grate

Grate firing is a type of industrial combustion system used for solid fuels. It now is used mainly for burning waste and biomass, but also for smaller coal furnaces.

• Capacities 0.3 to 175 MWth in industry and CHP
• Fuel fired per grate area 1-2 MW/m², maximum grate area 100 m²
• Grates are typical only suitable for coarse particles, for fine particles a spreader is required, increases max. capacity
• Primary air through the grate (also used for cooling) and secondary air
