What is the gas consumption for a 1000kW backpressure unit with an inlet pressure of 2.5 MPa and an exhaust pressure of 0.6–0.8 MPa?
Thread Content
A 1000kW motor in a facility wants to be replaced with a steam turbine; the inlet pressure is around 2.5 MPa and the exhaust pressure is 0.6–0.8 MPa. The steam is normally superheated. What is the steam consumption in this case?
The steam system in question still lacks an inlet steam temperature. If the steam turbine’s inlet pressure is 2.5 MPa at a temperature of 390 degrees, and the exhaust pressure is 0.6–0.8 MPa at a temperature of 250 degrees, then it’s a backpressure type unit; for a capacity of 1000 KW, approximately 13–17 tons of steam per hour are required
