What are the common features of industrial furnaces on the market？

Although the furnaces on the market are used in a wide range of industries and types, they still have many similarities. Let's study the specific ones. 　　

1) The basic theories of thermal engineering are the same, all based on several laws of thermodynamics. The fuel combustion, gas flow and heat transfer process in the furnace are basically the same. 　　

2) The basic components are the same. No matter what kind of furnace, it generally consists of the following parts: 　

① The part of the device that produces heat (such as combustion chamber, burner, electric heating element, etc.). 　

② Place the material part (such as furnace, hearth, trolley, etc.). 　

③ Smoke exhaust system (for fuel stoves, there must be flue, chimney, etc.). 　　

④ Auxiliary devices (such as furnace door, preheater, conveyor chain, etc.). 　

3) Low thermal efficiency and high energy consumption. Industrial furnaces are the main energy-consuming equipment in industrial production. The primary energy consumption each year accounts for about 1/4 of the country's total energy consumption. Especially in the thermal processing production of metallurgy, electromechanical and other enterprises, the energy consumption of the furnace accounts for more than 70% of the energy consumption of the process, and it is the largest energy user in production.
