BOILER MA INTAINENCE DEPARTMENT
Internally Fire Tube Boiler- 52m height, 60mm diameter.
Powder Coal is air blown into furnace forming the fire required
Water changes into steam at 370 Degree Celsius.
The saturated steam introduced into superheat tubes as the exit from
the furnace.
The superheated steam goes to the 210 MW turbine generator to
generate electricity.
