Tubular heat exchanger

water/waterstainless steeltitanium

The heat exchange element material of the device developed is a new type of silicon carbide engineering ceramics, which has excellent performance in high temperature resistance and thermal shock resistance. It is air-cooled from 1000 ℃ to room temperature, and no cracks appear after more than 50 cycles; thermal conductivity It is equivalent to stainless steel; it has good corrosion resistance in oxidizing and acidic media. In the structure, the thermal compensation is successfully solved and the gas sealing problem is solved better. The device has high heat transfer efficiency and significant energy saving effect. It can be used to preheat the combustion air or heat the process gas in certain processes, which can save primary energy, and the fuel saving rate can reach more than 30%. It can strengthen the process and significantly increase the production capacity. . Tubular silicon carbide insert high temperature heat exchanger is a new type of heat exchange device developed to replace metal heat exchangers and solve the defects of unreasonable long-term operation in high-temperature flue gas and the need for cold air to reduce the use effect. The heat exchanger made of this material is a replacement product of high-temperature flue gas waste heat recovery in the world. The tubular silicon carbide insert high-temperature heat exchanger has a compact structure and a large heat exchange area per unit volume. It is compressed by an internal spring to absorb thermal expansion. When the flue gas temperature is 1300°C, the air preheating temperature can reach 600°C or more.
