In recent years, water jacket heating furnaces have been widely used in oilfield surface engineering due to their reliable safety performance. However, water jacket furnaces are generally limited by the dew point temperature, and the exhaust gas temperature is high. The energy in the flue gas and the latent heat of water vapor cannot be effectively utilized (such problems also exist in vacuum furnaces and tube furnaces), resulting in the thermal efficiency of water jacket furnaces. Low energy consumption, energy waste and environmental heat pollution.

Conventional heating methods, such as steam heating, electric heating, infrared heating, etc., need a certain amount of time to reach a certain temperature, and it takes a long time for the temperature to drop when a failure occurs or heating is stopped. Its heating principle is to heat the surrounding environment, heat the surface of the object first by heat radiation or convection of hot air, and then conduct the interior of the object through heat conduction. This type of method has low efficiency and long heating time.
