摘要： An apparatus in the form of an air preheater for preheating air for combustion for a combustion process by acting upon the air with hot, NO.sub.x -containing flue gases from the same or an independent combustion process. At the same time, the NO.sub.x contained in the flue gases is reduced. A regenerative or recuperative type air preheater is used, with thoses surfaces of the heat exchange elements which are exposed to the flue gas being provided with a coating which acts as a catalyst for the NO.sub.x reduction. The heat exchange elements are coated only in a region which as a flue gas temperature greater than the condensation temperature of the reaction products of the materials contained in the flue gas and of the added reducing agent. The catalyst coating is provided on individual heat exchange elements which are successively disposed in the direction of flow of the flue gas in such a way that the respective coatings are optimally adapted to the reaction conditions for the flue gas temperature which exists in that region.

摘要： A method of treating reaction products which result from the flame combustion of fuels containing contaminants such as sulfur, chlorine, and fluorine compounds, and ash. Additives are added to the combustion chamber by means of a gaseous and/or liquid carrier flow accompanied by the formation of a veil which surrounds the burner flame. Subsequently, the remaining reactive additives, the reactive ash constituents, and possibly supplementary additives are reacted externally of the combustion chamber with the still uncombined gaseous contaminants of the reaction products.

摘要： A burner for combustion of nitrogen-containing fuels. The burner includes a core-air tube with centrally arranged oil atomizing lance, a dust tube surrounding the core-air tube, a mantle-air tube which surrounds the dust tube and is provided with an axially shiftable twist-blade ring arranged at the air inlet, as well as a burner opening which expands conically toward the combustion chamber. The core-air tube and the mantle-air tube are supplied from a main air conduit. Air jets or nozzles are provided in a concentric arrangement around the burner opening. These air nozzles are connected with the main air passage by conduits, and the air stream discharging from the air nozzles is regulated by a flap.

摘要： A method of ignition of a coal dust annular burner flame having an internal back flow region. The ignition energy is introduced centrally into the internal back flow region of the coal dust annular burner flame, and is delivered entirely or at least partially by a dust-ignition flame. The dust air-dust weight ratio for the dust-ignition flame is smaller than that of the main burner flame, being either 0.5 to 1.0, or 0.2 to 0.5, compared with a ratio of 1.5 to 2.0 for the main burner flame.

摘要： A method of continuously introducing additive, which is conveyed by gaseous and/or liquid carriers, into a turbulent reaction gas flow in the combustion chamber of a steam generator having dry ash withdrawal for selective removal, in a dry manner, of environmentally harmful gaseous noxious materials, such as sulfur, chlorine, and chlorine compounds, which are contained in a hot reaction gas flow which results after a complete or incomplete flame combustion of solid, liquid, or gaseous fuels. Depending upon the additive introduced, heat is stored and/or used for decomposition reactions. The additive, is first introduced at one or more input locations, due to locally different pressure conditions in the combustion chamber, into one or more recirculation flows which are within the system and are closed. The additive is subsequently withdrawn from these recirculation flows and is introduced into the reaction gas flow.

The burner has a core-air tube with a centrically arranged ignition device, a dust tube surrounding the core-air tube, and a mantle-air tube which surrounds the dust tube and is provided with an axially displaceable twist blade ring or impeller, arranged at its air inlet, as well as a burner opening which widens conically toward the combustion chamber. A dust-ignition burner is arranged concentrically in a core-air tube, and comprises an ignition-dust tube arranged concentrically around an igniter, and a mantle-air tube which surrounds the ignition-dust tube for the ignition-dust flame and is provided with an axially displaceable twist blade ring or impeller, arranged at its air inlet, as well as a conically widening outlet. The conical angle of the dust-ignition burner outlet is equal to or greater than the conical angle of the outlet of the main burner. The dust-ignition burner outlet terminates before the beginning of the conical widening of the main burner.

摘要： A method of scrubbing reaction products resulting from flame burning of fuels containing impurities such as sulfur compounds, chlorine compounds, and fluorine compounds. The scrubbing is accomplished by the addition to the fire chamber of additives which bind the impurities. The additives are supplied to the burner flame by way of a gaseous and/or liquid carrier medium flow, accompanied by the formation of a veil surrounding the burner flame.
