In order to save energy consumption, modern industrial production will use silicon carbide heat exchanger to collect a large amount of heat energy from high-temperature stoves. Graphite tail gas absorber, but why choose it instead of other equipment? It probably stems from its own superior characteristics.
Before the massive application of silicon carbide heat exchanger, the waste of industrial heat energy was avoided at home and abroad. Most of the methods used to recover heat energy were metal heat exchangers or switched heat accumulators. However, these devices occupy a large space and are not very efficient. This dilemma was not until the silicon carbide heat exchanger developed in China in the 1980s came out. Manufacturer of graphite heat exchanger
This type of heat exchanger is generally made of silicon carbide ceramics. During the heat exchange process, the flue gas with higher temperature is concentrated outside the tube, while the heated air is concentrated inside the tube. Both are distributed in a cross flow manner. Generally, silicon carbide heat exchanger can withstand a high temperature of more than 1500 ℃, so some flue gas with higher temperature can also directly enter the heat exchanger for heat exchange. Silicon carbide materials can better use the radiant heat in the high temperature flue gas and the radiant heat in the flame for heat transfer.
The properties of silicon carbide heat exchanger determine that its components have very good sealing performance, and the difference of thermal expansion between ceramic devices and metals is large, so it has good thermal compensation.
Compared with the traditional heat exchange equipment, the silicon carbide heat exchanger is still relatively young. It is light in shape, does not occupy too much space, and is not limited by the use. It can be switched to use without diluting and cooling the flue gas. This is also an important reason for its popularity in industrial production.
