Gas Fired Steam Boiler Comprisee of a fully automatic reverse flame package type steam generator,which consists of membrance type helical coil integral combustion chamber accommodated in S.S and insulated shell. The hot fuel outlet is connected to smoke tube preheater to preheat feed water.The steam generate dry saturated steam from 50kg/hr. to 800kg/hr. at maximum pressure 15kg/cm2.
Electrical connection to control panel and users point, All Structural work at users site. Electrical cabling. Any other items which is not specifically mentioned in our offer. All valves and fitting as desired. Circulation Pump with Electric motor .
· Pressure part comprising helical membrane coil facilitating three distinct passes within the Boiler and fabricated out of Boiler quality tubes.

Because of adopting the high efficiency heat transmits spiral gas tube, so the real output capacity of boiler is 10%-15% higher than rated. And either output capacity or thermal efficiency will not decline as extended the running time.
The hot water is mixed cycle and the water capacity is large, so the special protection is no need for damage caused by vaporization when power off.
The spiral gas tube is placed inside the boiler, so there will be no cool air entre. This can reduce heat loss and the working rate of this boiler is highest.
There many spiral gas tubes in the boiler and almost half of the boiler shell can be heated, so the temperature can up soon and the time was shorter than the water-tube boilers.
The special structure and materials make the boiler being with high safety.
The volume of the boiler is large and there is a dust separation device, so the primordial dust emissions density will be controlled much lower than the standard allowed.
