    摘要： A furnace system connected to a burner including a furnace for burning a fuel and air ejected from the burner into the furnace to produce a flame therein, and a combustion condition determining device for determining the conditions of combustion of the fuel in a zone of the flame extending along different strata thereof by collecting light in the flame at one point in the flame by moving such point. Signals outputted by the combustion condition determining device are utilized for monitoring or controlling the flame and controlling exhaust emission control devices for controlling exhaust emissions produced by the combustion of the fuel. Control of the conditions of combustion of the flame can be effected quickly with a high degree of precision by monitoring the flame.

    摘要： Nitrogen oxides (NOx) are removed from combustion waste gases by injecting gas (NH.sub.3) into the combustion waste gases in the presence of a metallic catalyst to deoxidize the nitrogen oxides to nitrogen and water, within a reaction tower having the catalysts moving through the reaction tower, so that thereafter the dust may be separated from the catalysts and the catalysts may be regenerated continuously, so that the regenerated catalysts may be returned to the reaction tower. The catalyst moves in a substantially closed path, and preferable downwardly through the reaction tower, with the ammonia gas and combustion waste gases moving in cross current through the reaction tower, with mixing being enhanced by a plurality of angled baffle plates. Regeneration is accomplished by washing the catalysts, particularly ferrous catalysts with water to remove ferric sulfates, thereafter providing ferrous sulfates on the surface of the ferrous catalysts, and thereafter heating the catalysts with combustion gases separate from the ammonia gases, to dry the catalysts prior to their moving into the portion of the reaction tower having therein the mixed ammonia gas and combustion waste gases.
