Transverse flame glass melting furnace with flue gas waste heat recovery function and working method thereof

Abstract

The invention discloses a transverse flame glass melting furnace with a flue gas waste heat recovery function and a working method of the transverse flame glass melting furnace, and belongs to the technical field of glass melting furnaces. A feeding hole is formed in one end of the kiln tank in the length direction, and a throat is formed in the other end; a plurality of flame nozzles are formed in the breast wall on one side of the longitudinal axis of the kiln tank, and a plurality of flue gas outlets are correspondingly formed in the breast wall on the other side of the longitudinal axis of the kiln tank; the flame nozzles and the flue gas outlets are sequentially arranged towards two sides from the highest stage to the last stage along the transverse axis of the kiln tank; the highest flame nozzle is provided with a combustion spray gun, and the other flame nozzles are provided with jet heat pumps; the flue gas outlet of the previous stage is connected with the first inlet of the jet heat pump of the next stage through a flue, and the second inlets of all the jet heat pumps are connected with combustion spray guns; the combustion-supporting gas source exchanges heat with smoke from the last-stage smoke outlet through the dividing wall heat exchanger and then is connected with the combustion spray gun, and the fuel supply system is connected with the combustion spray gun. The flue gas can be utilized for multiple times, heat loss is reduced, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the technical field of glass melting furnaces, and in particular relates to a cross-flame glass melting furnace with the function of recovering flue gas waste heat and a working method thereof. Background technique [0002] Glass melting furnace is the key thermal equipment for glass production. With the rapid development of the glass industry and the continuous improvement of the quality of refractory materials, the melting temperature of glass is also getting higher and higher, some of which are close to 1600 ° C, and the production scale is constantly expanding. Glass melting is an important part of energy consumption in the glass production process. With the energy shortage in the world, energy saving and emission reduction have been paid attention to by governments of all countries. At present, how to improve the energy utilization rate of glass production enterprises has become an important development direction of glas...
