Description

Technical Field

[0001] The utility model relates to the technical field of industrial furnaces, in particular to a reversing device for a heat storage type industrial furnace. Background Art

[0002] The regenerative industrial furnace is an efficient, energy-saving and environmentally friendly industrial furnace. It adopts regenerative combustion technology and has the characteristics of high efficiency, energy saving and low pollution emissions. The principle of the regenerative industrial furnace is to preheat the combustion air or fuel in the regenerative combustion chamber, and then enter the furnace for combustion. The high-temperature flame and flue gas generated enter another regenerative combustion chamber through the reversing device for heat exchange, releasing heat to the heat storage body, while its own temperature drops. In this way, the regenerative industrial furnace can make full use of the heat in the furnace, improve combustion efficiency and reduce energy consumption.

[0003] Compared with traditional industrial furnaces, regenerative industrial furnaces have higher combustion efficiency and lower pollutant emissions. Due to its efficient heat exchange and combustion method, it is necessary to change the direction of the gas in the furnace to reduce fuel consumption and the emission of greenhouse gases such as carbon dioxide. Since traditional regenerative industrial furnaces need to constantly change the direction of the gas during the combustion process, it is necessary to turn multiple valves to adjust. The operation is cumbersome and the functions of each valve need to be marked. Therefore, a reversing device for regenerative industrial furnaces is proposed to simplify the reversing operation.
