Structural type of electric heating tube furnace Tubular heating furnaces mainly include quick-installed tubular furnaces that directly heat crude oil and indirect-heated heat medium furnaces. Quick-installed tubular heating furnaces have great advantages in heating crude oil with a stable flow rate and low water content; It has advantages, but the operating cost and maintenance cost are high, and it needs to be equipped with heat medium circulation power system, heat exchanger, and heat pipe network.Vacuum brazing of elliptical corrugated horn The supporting cost of the system is high, and the nature of the heat medium needs to be replaced after the change, which increases the operating cost of the equipment; it is suitable for heat sources Places with more requirements and higher temperature requirements.Low temperature carburizing of 9Cr18 stainless steel surface The working process of the heating furnace is to convert the chemical energy of the fuel into heat energy. The heating furnace is mainly composed of two parts. One is the combustion system and the other is the heat exchange system. The heat exchange system exchanges the chemical energy of fuel combustion with the working fluid (heated medium) through various heating surfaces.HORIZONTAL MITRE BAND SAW MACHINE BS-912B Mainly water jackets, torches, tube bundles, etc. Combustion system is the general term for fuel combustion equipment, which is composed of feed supply system, burner, furnace, air supply and induction system, tail flue, etc. No matter what kind of structural type of heating furnace, its heat exchange system requires sufficient heat transfer Heat area, better heat transfer effect, minimize fouling during operation, and reduce the operating index of exhaust gas temperature.HORIZONTAL MITRE BAND SAW MACHINE BS-712R
