The main products are a series of products of heat pipe heat exchanger, waste heat boiler series, smoke detector heater economizer, evaporator, drying stove, and flue gas desulfurization dust removal and energy-saving and emission reduction. Environmental protection engineering, the product has been used in the steel, coking, industrial furnace, waste treatment, etc.

Flue gas heat exchanger is an important device in flue gas desulfurization system. Its function is to heat the net flue gas after desulfurization using the heat of the original flue gas. So the temperature of the original flue gas is reduced and the temperature of desulfurized net flue gas is increased to the required discharging temperature(about 80℃) and is discharged to the atmosphere through the chimney.

With the rapid development of silicon carbide technology, the price of silicon carbide has dropped sharply. At the same time, the weakness of sealing material of silicon carbide equipment has been gradually improved, and the advantages of silicon carbide over other anti-corrosion equipment have gradually emerged. Under special working conditions, silicon carbide has become the best material to replace tantalum. It has broad market prospects in sulfuric acid concentration, nitric acid, and related fields.

Application for silicon carbide tubular air preheater:

Silicon carbide has the characteristics of acid and alkali corrosion resistance, oxidation resistance, wear resistance, high-temperature resistance, high strength, and high thermal conductivity. Silicon carbide heat exchanger is an ideal choice. It is suitable for high concentration sulfuric acid, nitric acid, hydrofluoric acid, mixed acid, sodium hydroxide, bromine, and hydrogen bromide gas. It is mainly used for material heating, evaporation, cooling, condensation, and heat recovery.

Performance features of silicon carbide tubular air preheater:

1. High heat transfer performance

The thermal conductivity is much higher than other materials. The volume is smaller under the same heat exchanger.

2. High corrosion resistance

With very high corrosion resistance, oxidation resistance, and erosion resistance, silicon carbide tubes can be resistant to high concentrations of sulfuric acid, nitric acid, phosphoric acid, mixed acid, strong alkali, and oxidant, providing excellent long service life.

3. Excellent performance of high-pressure resistance and wear resistance.

4. Long service life, any single tube can be replaced for maintenance.

The modular structure is easy for shipment and assembly on site.
