4-ton gas industrial steam boiler made in China
1. The WNS oil/gas fired steam boiler is a horizontal internal combustion and three quick return boiler
with fire tubes.
2. It has fully wet back structure, and the high temperature flue
gas will be injected into the atmosphere after convection heat
transfer through the reversal chamber into the first flue tube
bundle and the front smoke box with turning 180℃ into the second
flue tube bundle.
3. The boiler has excellent technical performance of industrial
combustor and low water level alarm and low water levels, high
4. Besides, It has the features of compact structure, safe and
reliable design, fast installation, less pollution, low noise and
Boiler working principle and flue gas process
After the fuel and air are fully mixed, they are ignited and burned
to produce high-temperature flue gas. The boiler furnace is
After the high-temperature flue gas is burned in the furnace, it
enters the second return thread pipe bundle through the back
combustion chamber, and then passes through the front cigarette
box. Into the third return thread pipe bundle, and finally
discharged into the atmosphere.
The boiler furnace, the back combustion chamber and the smoke pipe
are all immersed in water. During the flow of the flue gas, these
components exchange heat by the temperature difference between the
flue gas and the water, and the steam is generated by the main
Rated Steam Pressure
