  • Steam Boilers Applications Classification

    Pump the water into the boiler shell through the economizer with the help of a non-return feed valve till the fire tubes submerge in it. The fuel is charged through the fire holes on to the grate and burnt. The hot gases travel upto the back end of the fire tubes transferring about 83% of the total heat to the water.Learn More
