The atmospheric pressure horizontal hot water boiler has the high efficiency of all wet back three return

Product introduction:

CWNS series automatic oil (gas) horizontal hot water boiler (utility model patent), the use of horizontal three-return wet back structure, improve the boiler operating environment, improve boiler efficiency and service life; All flue gas channels are placed in water, the tail is equipped with waste heat water tank and perfect insulation outsourcing design, and the smoke box seal adopts labyrinth structure to avoid the smoke box leakage phenomenon. The thermal efficiency of the boiler is as high as 90~97%, and the combination of corrugated furnace and conical furnace with good expansion performance is adopted. The furnace furnace size is consistent with the flame, and the flue gas flow area is reduced to make the flue gas flow at the same speed, ensuring the heat exchange time of high temperature flue gas in the furnace, and achieving the best heat transfer effect 

Product advantage:

1, boiler products
Horizontal internal combustion three return full wet back design, 100% corrugated furnace, with good thermal scalability, water cooled recombustion chamber, recombustion chamber and the rear tubesheet edge butt, the lowest stress, more reliable quality.
2, large diameter corrugated furnace gall
The combustion chamber of the boiler is composed of a large diameter full corrugated furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.
3. Sufficient heat
Boiler heating area is more than 25 square mete rs/ton design configuration, fully absorb effective heat, low smoke exhaust temperature, small heat loss, to ensure sufficient output, high efficiency.
