Abstract
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 firing zone, and to an ash discharging zone. A suction fan is provided at the initial windbox to downdraft an oxygen-containing fuel to the bed at an ignition zone closely adjacent said charging zone. The remainder of the bed is subjected to updrafting for firing the bed to reduce it to ash.
