>> Smoke gas three pass
WNS series gas oil fire tube steam boiler is a kind of safe and high efficiency heating supply equipment with full automatic control system. It is one patent product of Sitong Boiler, the patent number is 2014 2 0504448.2. This series oil gas fired boiler is horizontal type fast assembly fire tube boiler with three pass structure, it has compact structure, small water volume, strong load adaptability and low water quality requirement etc.features.
Smoke gas three pass
The flaming torches formed by burning the fuel is filled in the corrugated furnace through the burner and transfer radiant heat through the furnace wall, This is the first-pass.

The high-temperature flue gas generated by the combustion gathers in the back-combustion chamber and turns into the second pass(i.e: the threaded tube bundle region). After the convective heat exchange, the flue gas temperature is gradually lowered to the front smoke box.
The third-pass boiler flue gas is diverted from the front smoke box to the long thread smoke tube, and then enters into the economizer and the condenser through the rear smoke box, and finally flows into the chimney, discharges into the atmosphere.

>> Features
Fully wet back combustion chamber

1. Fully wet back combustion chamber

The reburning chamber abutting with the rear tube plate, boiler is 100% fully butt welded, lower stress, and reliable quality.

2. Large-diameter corrugated furnace

The boiler combustion chamber is composed of large-diameter corrugated furnace, larger combustion space, completed combustion, larger heating area, higher thermal efficiency.
Fully wet back combustion chamber
Multi-functional anti-explosion device

3. Multi-functional anti-explosion device

The boiler rear plate equip with anti-explosion device which connected to the furnace, it can release the pressure and self-reseted once fuel deflagration in the furnace. At the same time, it has the function of fire watching and inspection.

4. High thermal efficiency

The economizer was equipped at the rear of boiler, which can reduce the exhaust gas temperature and increase boiler feed water temperature,improve efficiency can reach to 96% (fuel: natural gas ).
