1. Steam heating
Many chemical industrial parks have their own thermal power plants, and hot steam is a very convenient and economical heating method. High temperature steam is exchanged through the jacket of the reaction kettle, which is suitable for mass production and does not have high requirements for temperature control accuracy. Due to the poor stability of steam heating and the low accuracy of temperature control, it is not suitable for small and medium-sized experiments, Also, it is necessary to install steam pipelines. In general, the control range of water vapor temperature is 200 degree .
2. Gas thermal oil furnace
If there is no steam supply or the pressure of the steam supply is insufficient to reach the required temperature, the gas thermal oil furnace uses gas to heat the thermal oil, and then uses gas to heat it. This type of device also uses gas as energy and is suitable for high-temperature pipeline factories with gas.
3. Electric heating thermal oil furnace
Electric heating is the simplest and most convenient heating method that does not require any boilers or any gas or steam. It can be heated by simply turning on the power supply, with a wide temperature control range that can be easily adjusted from 0 degree to 350 degree . Electric heating molds are generally used for small and medium-sized experiments, as well as some reaction kettles with high temperature control accuracy requirements. Due to the high temperature stability of electric heaters, Moreover, electric heating is a clean energy source that does not generate open flames or environmental pollution, and its safety is also the highest.
