It is composed of heating furnace body, regenerator, reversing system, fuel, air supply and smoke exhaust system. The regenerator is the main body of the waste heat recovery of the flue gas of the regenerative heating furnace. It is a room-like space filled with the regenerator and a part of the flue gas and air flow channel. In heating furnaces, the regenerators are always used in pairs. One furnace can use one pair, several pairs, or even dozens of pairs. More than forty pairs are used in some large-scale regenerative heating furnaces in China.
Furnace temperature is more even. Because the furnace temperature is evenly distributed, the heating quality is greatly improved, and the product qualification rate is greatly improved.
