Grate-firing of biomass for heat and power production

Grate firing is one of the main technologies that are currently used in biomass combustion for heat and power production. Grate-fired boilers can fire a wide range of fuels of varying moisture content and show great potential in biomass combustion [2], [3], [4].

Detroit Stoker - Detroit Stokers - Hydrograte

Coarser, heavier fuel is spread evenly on the grate forming a thin, fast-burning fuel bed. The combination of suspension and bed burning makes this method of firing extremely responsive to load demand. RELIABILITY UNDER VARYING LOAD CONDITIONS: Combines advanced spreader stoker technology with automatic ash discharge and water-cooled grates

Bioenergy Projects Technology Review - BC Hydro

Jul 22, 2015 · A popular travelling grate is the air-cooled vibrating grate. Fixed grates are an older design that have to be manually de-ashed. The other technologies have automatic ash removal. In British Columbia pulp mills, most of the older boilers have travelling grates. The newer boilers at the Powell River and Port Alberni mills are BFB boilers.

Coal combustion characteristic in vibrating grate stoker

In vibrating grate, the combustion rate of sub-bituminous and lignite coal in vibrating grate increase 56.5% and 25.9%, respectively, compared with in fixed grate. Application of vibrating grate instead of fixed grate in boiler can minimize the furnace size room because of higher heat release rate per area.
