3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.

4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in the threaded pipe, avoid the accumulation of dust in the tube.
