Structure of the boiler

Our products steam boiler adopt the most international mature three return all wet back structure,safe and reliable.Using Waveform furnace,not only strengthened the flue gas disturbance,but increased radiation heat transfer area;Both increased furnace stiffness,and effectively reduces the furnace heat stress;Both enhanced heat transfer effectiveness and promote fuel in the combustion chamber;The heating surface layout is symmetrical, structural strength is relaible,the water cycle system is reasonable.Up boiler water capacity is large.Steam room and steam quality is good.small fluctuations in the water level of operation also is good.The distance between two boilers are long,pipe diameter is large,ensuring good natural cycle.The unique setting of gas furnace and the heat design to gurantee the boiler heat losses are most minimal.

Main superiorities

1.After preseting, the purge functions to improve the working conditions of combustion and longevity.

2.The unique design of the combustion chamber, increasing the radiation heating furnace area, reducing the size of the boiler, reducing NOx emissions.

3.Front and back breathing tube boiler box is a multi-level sealed approach to ensure that no leakage breathing.

4.The large steam room and high quality steam.

5.The horizontal structure has adequate heating, heat transfer is full ,load changes operating is stable in boiler, high combustion efficiency. Furnace biliary low settings, the water level of security is large. Evaporation area of steam and steam quality is high.
