The series of boilers adopts an excellent design concept. Through the condensing device, the heat of the flue gas is used in cascade, and the residual heat in the flue gas is fully absorbed, so that the boiler efficiency is greatly improved.
This series of boilers is designed with a classic shell type, full-wet back, down-flow and three-pass design structure. The fuel is fully burned in the large-capacity combustion chamber, and the combustion heat load is low, which can greatly reduce the emission of harmful substances such as CO and NOx.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water flow rate and excellent water circulation system. Boiler heat absorption rate and thermal efficiency are high.
The shell-type fire tube structure is adopted, and the flame is burned downward to enhance the heat transfer effect, thereby reducing the convective heating area; the flow resistance of the flue gas is small, the running power consumption is low, and the operation cost is saved.
