The thermal work of industrial furnace refers to all the thermal processes completed in the furnace, including the sum of fuel combustion, gas flow and heat exchange. The quality of hot work in furnace affects the production process.

And technical and economic indicators. Therefore, the structure and operation of industrial kilns should focus on ensuring the best thermal engineering.

Industrial kiln is a kind of complex thermal equipment. It is composed of furnace, combustion device, smoke exhaust device, air and gas preheating device and other auxiliary devices.

The furnace of industrial kiln is a closed space made of refractory materials. In the furnace of flame furnace, there are high-temperature furnace gas, heated materials and Furnace wall. The three objects exchange heat with each other in the furnace. In this process, the final heat released is high-temperature furnace gas, and the lowest temperature is obtained.

The heated material, and the furnace wall acts as an intermediate medium for heat transfer in the process of reheat exchange.
