WebJun 7, 2013 · • Medium Pressure (MP). Condensate return pressure is being returned between 16 to 99 psig. • High Pressure (HP). Condensate return pressure is returned at 100 psig or higher. • Makeup Water (MW). Water is added to the steam system to offset any condensate lost in the system that is not being returned to the boiler operation. WebWhile it is true that higher pressure steam has more overall energy in the system, low pressure steam still has plenty of energy to carry out a great amount of work, such as heating large buildings. For example, if a building uses steam for heat, it typically runs at a pressure no higher than 2 PSI—seemingly miniscule! tsn coe

WebFor example, dry saturated steam at 60 bar g would have to be reduced to approximately 10.5 bar g to produce dry saturated steam. Any less of a pressure drop will produce wet steam, while any greater pressure drop would produce superheated steam. Equally, the state of the supply steam at any pressure will influence the state of the throttled steam. WebQuestion: Given: A thermal power plant with a re-/superheating stage between the high-pressure and the medium-pressure steam turbine is given with the following parameters. mFuel =110th;LHVFuel =26.3MJ/kg;Poc=3.3% of Wgrosa m்EQ =900t/h;CBEG=1,17 kJ/kgK;TEG=180∘C;TSur =15∘Cηis,ST=0.85;ησ=0.98;ΔT0−1=2 K Isentropic expansion and … WebAug 22, 2024 · High-pressure steam applications require more than 15 PSI.
