Industrial furnaces are divided into drying furnaces, heating furnaces, heat treatment furnaces, melting furnaces, etc. according to their uses. Industrial furnaces are divided into low-temperature furnaces, medium-temperature furnaces, and high-temperature furnaces according to the temperature. Industrial furnaces are divided into fuel furnaces and electric furnaces according to the energy used. Fuel furnaces are divided into oil furnaces, gas furnaces, coal-fired furnaces, etc. Electric furnaces are further divided into resistance furnaces, induction furnaces, far-infrared furnaces, etc.
Compared with other equipment, industrial furnaces have the following characteristics:
(1) First of all, industrial furnaces are thermal processing equipment. Its temperature is high and it needs to be supplied with energy to work.
(2) The working environment temperature of the industrial furnace is relatively high, so attention should be paid to high temperature burns.
(3) The operation of industrial furnaces must be carried out according to the regulations. The operation of fuel furnaces should pay attention to the problem of explosion protection, and the operation of electric furnaces should pay attention to the problem of electric shock.
(4) The design and installation of industrial furnaces fully consider the characteristics of thermal expansion and contraction, and pay attention to the transfer relationship and installation requirements of various components.
(5) Improving the thermal efficiency of industrial furnaces is the core of industrial furnace design and operation.
