operational systems of fire tube boiler

  • Operation of water tube boilers explained

    Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster

This injects steam into the feedwater to increase the temperature to 160°F to180°F or so to remove oxygen. Scale is a very effective insulator that will cause a loss of heat transfer efficiency and eventually tube
