gas oil fired steam boiler

1.Adopting the latest technology,it is designed with a combustion chamber with large volume,it is equipped with a world –know burner ,making the combustion more sufficient and ensuring higher efficiency and lower failure rate

2.It adopts advanced corrugated  furnace pipe structure,increasing the heat surface area,and satisfying     free expansion of the furnace pipe after heating.

3.It uses a spirally corrugated tube,strengthening heat transfer and eliminating welding stress.

4.It adopt wet back structure with high reliability and low maintenance cost.

5.It has protective functions of overtemperature,overpressure,water shortage,leakage detection and         flameout,ensuring safe and reliable operation

II.Advantages of gas oil fired steam boiler

1.High Efficiency 95%: Wet-back technology replace traditional dry-back design, effectively increase boiler’s water heating surface, and protect the smoke-box from the over-temperature damage. Three passes structure, Large diameter corrugated furnace and corrugated fire tubes to increase boiler heating surface to better absorb the heat. Additional, it also equipped with condenser(finned tube type) to full using the massive latent heat in the exhaust gas; and the high temperature condensing water also can be fed into the boiler again.

2.PLC Automatic Control: WNS series gas oil steam boiler adopting advanced touch screen control cabinet and digital computer full automatic controller. The water feeding system controller can automatically regulate water feeding rate, make sure boiler's water stay on the standard water level. According to boiler's working pressure, burner controller can automatically regulate output power; the burner's output has one- two- three stages fire.

3.Convenient Installation/ Maintenance: WNS series gas oil steam boiler gets compact structure and openable front/ back smoke boxes, man-hole, hand-hole, platform ladder. Above designs are convenient for installation, maintenance.

Function:Burner automaticallly ignite, flameout and switch of big fire and small fire;
Overpressure protection; leakage detection ;
Automatically feed water and stop the pump;
Alarm for low water level and high water level, interlock for super low water level;
Alarm and shutdown for too high exhaust gas temperature.
