What are the protections of boiler / HRSG ?

1. Boiler/ HRSG Drum Safety Valve.

2. Main Steam Line safety Valve.

This 2 is most important protection for all High Pressure Boilers.

3. Steam Temperature.

4.Steam Pressure .

5.Drum Level Gauge & Transducer (  2 out of 3 Logic)

6. Continuous Blow Down & / IBD ( For Silica Carryover in Turbine).

7. Automatic Steam Vent Valve ( In case load reduces/ due to any reason Pressure start increasing ), Vent valve will open & maintain the pressure).

8. Water chemistry for Long-life of Boilers & HRSGs.

9.Drum Level maintain through Feed water Make up valve.( 2 out of 3 logic of Level Tramsmeter & Flow transmeter).

10. Water Sealing in High pressure boiler is the Ingress Protection.
