Energy Saving Industrial Steam Boiler Condensing Gas Boiler for Sale
 WNS series natural gas oil condensing steam boiler takes the advantage of high efficiency condenser and economizer, to absorb the sensible heat in the high temperature flue gas and the latent heat released from the vapor condensation, to improve the thermal efficiency.
energy saving industrial steam boiler condensing gas boiler for sale 
How the WNS natural gas oil condensing steam boiler works?
Natural gas fuel usually contains a lot of hydrogen, which produce a large amount of water vapor . Burning per
1 Nm3 natural gas can produce 1.71 kg water vapor, latent heat of the vaporization is about 4000KJ,
occupying about 10% low catorific value of natural gas. When the exhaust gas temperature is too high, water
vapor condense and release heat, flows follow the flue gas and cause the waste of heat. Meanwhile, high
temperature flue gas also takes a lot of sensible heat, big loss of flue emission. While installed with condenser
can overcome these disadvantage and save energy, improve the thermal efficiency.
Characteristic of WNS natural gas oil condensing steam boiler
1. Equipped with condensator and economizer, the thermal efficiency can reach 105%.
2. High quality of condenser, using the stainless steel, avoid low temperature corrosion, long working perid.
3. Condenser is installed on the top of the boiler, do not cover extra space, condensation water on the
conduction surface can also flow naturally.
4. Large heating area, warm up and pressure boost fast, easy operation.Â
5. Adopt the wet back structure and corrugated furnace, greatly improve the heating area and the strength.
6. Equipped with high quality and high performance burner, ensure safe and reliable combustion.
7. The controller dopts Siemens/Delixi electric conponents, high degree of automation on water temperature
and temperature, etc.
8. Small size, save the capital investment.

3) The spirally corrugated tube strengthen the disturbance of flue gas, high heat transfer efficiency.
4) The boiler shell use aluminium silicate board for heat preservation, low heat loss.
5) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature,
the thermal efficiency could be increased to as high as 98%.
2. High Safety Performance
1) Complete gas manifolds and protection system, including filter, pressure regulating valve, and solenoid
valve, etc., to ensure the safety performance of fuel.
2) Reliable boiler auxiliaries and multiple safety protection devices, such as pressure controller, pressure
transmitter, water level alarm, safety valve, etc.
3) Equipped with explosion proof equipment, discharge high energy when deflagration happened in furnace,
to ensure the boiler operate safety and efficiently.
3. Full Automatic Control
Adopts PLC full automatic intelligent control cabinet and interlock protection program, has the protection
function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and
phrase-lacking or overloading of motor, etc.
4. Low Cost
