How many safety valves are installed in total in the main and reheat systems? Where are they respectively? What are the values for each action?
A total of 10 spring-loaded safety valves and one electromagnetic pressure relief valve are installed in the main and reheat steam systems. There is 1 on the side of Drum A and 2 on the side of Drum B ； 2 spring-loaded safety valves and 1 electromagnetic pressure relief valve at the outlet of the final superheater ； 2 spring-loaded safety valves at the inlet of the wall-type reheater and 3 at the outlet of the final-stage reheater. The pressure values are as follows: Drum #1 is 20.61 MPa, Drum #2 is 21.03 MPa, Drum #3 is 21.23 MPa; Superheater outlet #4 is 19.08 MPa, Superheater outlet #5 is 19.65 MPa; the electromagnetic pressure relief valve is at 18.89 MPa ； The reheater inlet pressures are 4.34 MPa at #7, 4.47 MPa at #8, 4.03 MPa at #9, 4.07 MPa at #10, and 4.15 MPa at #11.
The information on the first floor is too detailed. As a supplement, we have only 8 valves in total; among them, the final superheater and the inlet of the wall-type reheater each have only one spring-loaded safety valve
The person on the first floor explained it in too much detail. Let me repeat it: a total of 10 spring-loaded safety valves and one electromagnetic pressure relief valve are installed in the main heating and steam system. There is 1 on the side of Drum A and 2 on the side of Drum B ； 2 spring-loaded safety valves and 1 electromagnetic pressure relief valve at the outlet of the final superheater ； 2 spring-loaded safety valves at the inlet of the wall-type reheater and 3 at the outlet of the final-stage reheater. The pressure values are as follows: Drum #1 is 20.61 MPa, Drum #2 is 21.03 MPa, Drum #3 is 21.23 MPa; Superheater outlet #4 is 19.08 MPa, Superheater outlet #5 is 19.65 MPa; the electromagnetic pressure relief valve is at 18.89 MPa ； The reheater inlet pressures are 4.34 MPa at #7, 4.47 MPa at #8, 4.03 MPa at #9, 4.07 MPa at #10, and 4.15 MPa at #11.
