Abstract

PURPOSE: To control effectively the nature of exhaust gas and the thermal load of furnace of corner firing type combustor by providing injection nozzles near corners of the furnace walls which nozzles can vary the orientation of injected gas preliminarily adjusted in amount or pressure.
CONSTITUTION: In the combustor having four burners 1W4 at four corners of the furnace, there are provided four injection nozzles 5W8 near corners of the furnace walls which nozzles inject in a selected direction fire-ball control gas recirculater (FCGR) at least one of whose injection rate and pressure is preliminarily adjusted. With such a construction, FCGR supplied from a coal economizer not shown and, for example, increased in the pressure is intorduced into the furnace through the injecting direction variable nozzles 5W8, thereby controlling the size of fire-ball to obtain a preferable characteristic of exhaust gas and an improved thermal load of furnace.
