Due to various limitations of metal heat exchanger in industrial production, silicon carbide heat exchanger has gradually replaced it. The latter is outstanding in solving the problems of high temperature resistance and corrosion resistance of block hole graphite heat exchanger.
Compared with silicon carbide heat exchanger, metal heat exchanger can only be used at low temperature. It should be noted that it can not be used directly when the gas temperature is very high. It needs to infiltrate some cold air and protect at high temperature.
The use of silicon carbide heat exchanger is relatively simple, fast, environmentally friendly and energy-saving. It does not need to penetrate cold air or conduct high temperature protection like the metal heat exchanger, and the investment in subsequent maintenance work is relatively small, so it does not need any operation on the heat exchanger.
The silicon carbide heat exchanger can adapt to any kind of environment. It can recycle the remaining heat of industrial cellar furnace and solve the problem that the waste heat of high-temperature cellar furnace cannot be recycled. Metal heat exchangers can be replaced at high temperatures.
Our country has regulations that require silicon carbide heat exchanger to work at a high temperature greater than or equal to 1000 ℃. Because of its outstanding high temperature resistance, the higher the temperature, the better the effect will be, and the more energy will be saved.
In addition, silicon carbide heat exchanger can also solve the problems of chemical corrosion and heat exchange in the chemical industry. Its adaptability is very strong. It has unimaginable high temperature resistance and endurance. Its anti-oxidation performance is also very good, and its service life is very long.
