BOILER PROCESS

                 

Boiler is used for producing steam.

OIL FIRED BOILER

Types of Boiler:-

1.     Oil Fired

2.     Gas Fired

3.     Coal fired

4.     Atomic Fired

5.     Re actor

There are two methods of Steam Production 

1.     Fire Tube Boiler – Fire inside the tube and Water outside the tube.

2.     Water Tube Boiler – Water flow inside the tube and Fire outside the tube.

•  DM water goes to Heat Exchanger to preheat the water.

•  Heated water goes to dearator.

•  Water comes From dearator to  Feed pump.(Note: through Booster pump and Feed pump)

•  Pressurized hot water goes to water seal Drum.

•  Drum level should be maintained 50  %

•  Water comes from seal drum to Mud Drum.

•   Here, Water heated by Burners for Boiling.

•  Temp. Up to 435⁰c to form a Steam.

•  The steam goes to Economizer for further heating(i.e. By 530⁰c)

•  After that this steam goes to Super Heater.

•  From super heater to steam conditioning valve.

•  Now, saturated steam comes out from conditioning valve.

• Saturated steam flow goes to Turbine for rotate the Rotor.
