Ceramic heat exchangers have the following characteristics: a. High temperature resistance, corrosion resistance, good heat exchange effect and high energy saving rate. But the part where the metal heat exchanger is placed on the ceramic heat exchanger is quickly burned out.Alternate Vacuum Brazing Process for Aluminum Alloy Materialsb. The use method of the ceramic heat exchanger is direct, simple, fast, less one-time investment, low investment cost, stable heat exchange temperature, high efficiency, long life, no blockage, no air leakage, easy to replace, and there is no gas when switching waste away.The situation and solution of the scrapped vacuum furnace c. In terms of service life, the ceramic heat exchanger is several times or dozens of times that of the metal heat exchanger under the same conditions.MIM Process Equipment If the heat exchanger is not used, the temperature of the combustion-supporting air is normal temperature (-10℃-40℃), but the temperature of the combustion-supporting air heated by the ceramic heat exchanger can reach 300℃-800℃, which can not only achieve the purpose of energy saving, but also improve the environmental benefits. The waste heat recovery and utilization of the heating furnace can achieve an energy saving rate of 1% to 2%.
