a. It adopts straight type layout, utilizing ash dead-weight to self-remove, keeping heat surface clean and improving boiler heat transfer efficiency.

b. The boiler adopts special sealing devices to reduce boiler air leakage and improve boiler efficiency.

All the pressurized parts of the boiler are suspended structure, to ensure free expansion, as much as possible to reduce the impact of fatigue stress welding, high operating safety.

Exhaust gas and water and water vapor heat transfer are in the outer surface of the heat pipe, and the exhaust heat pipe outside the fin, so that the heat transfer area increases, heat transfer is strengthened, so the heat transfer coefficient has been greatly improved.
