1. This is a modern high pressure, water tube boiler working on a forced circulation. 2. The circulation is maintained by a centrifugal pump, driven by a steam turbine, using steam from the boiler. 3. Feed water is supplied to economiser from hot well which is passed to separating and storing drum. 4. Water from separating and storing drum, flows by gravity to circulating pump. 5. Circulating pump circulates the water to set of tubes known as convective evaporator and then radiant evaporator. 6. By the time, water leaves the radiant evaporator, it converts into steam. 7. This steam is passed through storage and separator drum. 8. From separator and storage drum steam is fed to super heater to superheat. 9. The superheated steam is passed to main stream to supply for required application.
Lamont boilers generates 45 to 50 tones steam per hour at 130 bar with 5000 C.
