The steel plate and cast fin plate air preheaters produced by our company are based on the technical characteristics of this type of air preheater from foreign companies. The plate air preheater products developed on this basis have a wide working range and heat transfer efficiency. It has the advantages of high height, compact structure, small resistance reduction, good corrosion resistance, low cost and long service life. It has been widely used in petrochemical, electric power, metallurgy and other industries. According to the characteristics of different working conditions, steel plate air preheater, cast fin plate air preheater, or a combination of the two can be selected.

When the flue gas temperature is greater than 600 degrees, the cast finned plate air preheater is selected, and high nickel alloy castings are used to effectively improve the high temperature creep resistance and erosion resistance, and ensure the efficient operation of the air preheater temperature. When the flue gas temperature is less than 250 degrees, the cast finned plate air preheater is selected and cast iron parts are used to effectively improve the resistance to low temperature dew point corrosion and erosion, and ensure the stable and efficient operation of the air preheater. When the flue gas temperature is between 250 degrees and 600 degrees, steel plate air preheaters of different materials can generally be selected. Considering the anti-erosion and corrosion resistance, cast iron double-sided fin plate air preheaters can be selected to ensure air preheating. The heater operates stably and efficiently. Within the temperature boundary range, the combined steel plate cast air preheater can ensure high heat transfer efficiency, high resistance to low temperature dew point corrosion and erosion resistance, and ensure stable and efficient operation of the air preheater.

At present, the plate air preheater produced by the company has won the national utility model patent. Patent No. Zl200820034887.6
