摘要： A structure of a boiler of the type that pulverized fuel is burnt within a square barrel-shaped furnace (01) having a vertical axis, is improved so that ignitability is improved and a produced amount of NOx is decreased. Burners (21,22) for injecting pulverized fuel-air mixtures (09) are disposed at the central portions of the vertical furnace sidewalls and are inclined downwards with respect to a horizontal plane. Also, nozzles (27) for feeding air (29) are disposed under the respective burners.
