Can saturated steam at 1.0~1.2 MPa be used in steam turbine generator sets?
Thread Content
As the title suggests, can saturated steam at 1.0~1.2 MPa be used in steam turbine generators? Currently, one company is facing difficulties with high-temperature exhaust gas emissions; for example, a waste heat boiler can be used to recover the heat from the flue gas, generating 20 t/h of saturated steam at a pressure of 1.0~1.2 MPa. I have the following questions: 1. At this steam pressure level, are the water treatment requirements specified in the electrical industry standards (for steam pressures of 3.8 MPa and above) applied? 2. Are there mature and reliable steam turbine generator sets driven by low-pressure saturated steam? 3. If there are mature low-pressure saturated steam turbine generators, does the turbine possess condensate extraction capability? As this project also undertakes the task of centralized heating. The parameters of the heating steam are 0.8 MPa saturated steam. Urgent online!
Steam turbine generators driven by saturated steam are not commonly seen in power plants and chemical plants; nuclear power plants generally use saturated steam for driving such generators； The pressure drop from 1.0–1.2 MPa to 0.8 MPa is relatively small, so the amount of electricity generated will also be limited. It is likely that condensate will be produced during this power generation process, which could have a significant impact on the turbine blades. I think it would be best to install a pressure reducing valve to lower the pressure directly for use in heating purposes.
1.2 to 0.4 is okay, but it results in high steam consumption. There will be no problems as long as the overall steam balance is satisfied
This type of saturated steam power generation works fine; we have carried out several low-pressure saturated steam power generation projects. Is the project still around?
