LOW POLLUTION HEAT ACCUMULATING TYPE COMBUSTOR FOR USE OF INDUSTRIAL COMBUSTION FURNACE

摘要

PURPOSE: A low pollution heat accumulating type combustor is provided to prevent explosion and suppress generation of NOx during combustion reaction, while increasing durability of combustion furnace. CONSTITUTION: A combustor comprises a first combustor(100) and a second combustor(200) disposed adjacent with each other; and fuel injection nozzles(112,212). A high temperature air for combustion and exhaust gas are supplied or discharged periodically through air nozzles(111,211) for combustion, while a fuel gas is supplied continuously. The fuel injection nozzles are disposed within the air nozzles for combustion, and air orifices(115,215) are disposed within the air nozzles for combustion so as to apply a precessional motion to the air for combustion.
