What are the definitions of critical, supercritical, and ultra-supercritical power plants?
Thread Content
As a technician at a valve supplier company, I often encounter problems related to power plants in my work. I’m not sure how supercritical and ultra-supercritical conditions are defined Also, are there terms like gas turbine and steam turbine? I’m not sure if it’s appropriate to post this here, but I’m still hoping everyone can help. Thank you!
Supercritical and ultra-supercritical refer to conditions where the steam pressure is above the critical value. A supercritical pressure boiler is one whose main steam pressure exceeds the critical pressure of 22.12 MPa. Typically, the main steam pressure of large-capacity supercritical pressure power plant boilers is set at around 24.5 MPa, with some having even higher values. When the main steam pressure exceeds 27 MPa (see steam parameters), it is also known as an ultra-supercritical pressure boiler. Valves in pipelines generally correspond to specific pressures
Thank you, up above. I was wondering if anyone could talk about the steam engines in power plants? ? Is it called a turbine in thermal power plants? Is one that burns gas directly called a gas turbine? Also, I was wondering if anyone could provide some good information on waste-to-energy generation? Thank you all! :handshake :handshake
A unit that uses high-temperature steam to drive a turbine to generate power is called a steam turbine generator set, while one that uses high-temperature gas directly to drive a turbine to generate power is called a gas turbine generator set.
Waste-to-energy generation primarily utilizes the calorific value of waste; after combustion, the heat is absorbed by boilers to produce steam, which is then used to drive turbines to generate electricity. The main difference from ordinary power plants lies in the boiler.
Thank you, luoshunxu. I will learn more based on the information you provided. Thank you! :victory:
Hello everyone, how are our power plants distributed? Are coal mining areas mainly used for thermal power generation, and is pollution from such power plants relatively severe? Is power generation carried out in the eastern regions and along the rivers? Are gas power plants located in areas with abundant oil and gas reserves, such as Xinjiang? Also, I wonder if waste-to-energy plants are actually in use in our country?
