In presence of boiler and furnace burning process, waste heat is necessary to recover in a bid to re-use the heat from exhaust and flue gas, as well as to reduce environmental impact and long-term operation costs. Our design team will give proposal based on heat exchanger expense to that of waste heat profit and gas saves annually.

While trying to avoid sulfuric corrosion during operation, our team has consulted with experienced operation plants and advised following points to end user:
1. Increase furnace temperature, reduce the excess air coefficient, to limit formation of sulfur trioxide;
2. Use additives(spray ammonia) to neutralize sulfur trioxide at boiler tail;
3. Increase wall temperatures higher than dew point to prevent condensation of H2S...;
4. Use corrosion-resistant materials. ND steel, SS316, etc.

CHARACTERISTICS

I.TUBE/FIN-HIGH FREQUENCY WELD, BARE TUBE, ROLLED FIN TUBE, ETC.

Performance features:

1. Maximum length of 6 meters, which reduces connection points and probability of leakage at joint;

2. Full contact welding between tubes and fins, heat area is more than 8 times of smooth/bare tube, less flow resistance;

3. Longer service life, high mechanical strength of fin and tube combination with more than 200MPa tensile strength.
