FBC ADVANTAGE OVER CHAIN GRATE STOKER BOILER - …

Nov 06, 2017 · Raw coal is burned in furnaces or chain grate boilers. In this work, we studied the chamber combustion mechanism in a chain grate boiler (CGB) with a capacity of 20 t/hr. A mathematical model was built using Computational Fluid Dynamics (CFD). It was found that chamber combustion with swirl burners instead of grate firing has a positive effect on NO emissions.

New Method for Controlling Combustion in a Grate Boiler

Oct 19, 2020 · The ignition condition of chain grate is poor. The coal fires mainly depend on the radiant heat of the furnace flame and the arch, so the coal above fires first and then burns down gradually. As a result of this combustion process, distinct regional stratification appears on the grate, as shown in …

What Is A Chain Grate Boiler

A cross fire stoker adapted to burn a difficultly ignited fuel is disclosed, together with a method of operating the stoker. The stoker is adapted to burn such fuel in a furnace not having large front or rear arches and includes a horizontal traveling grate within the furnace which is adapted to convey a bed of solid carbonaceous fuel from a charging zone, through an ignition zone, through a
