Steam pressure rating and temperature
Thread Content
Steam is generally classified into ultra-high pressure steam, high-pressure steam, medium-pressure steam, and low-pressure steam. The values are as follows: Pressure (kpag), Temperature (°C). Ultra-high pressure steam VHPS: 11300, 510; High-pressure steam HPS: 3500, 380; Medium-pressure steam MPS: 1200, 270; Low-pressure steam LPS: 400, 235. Are there any differences?
There are too many differences. In terms of the steam pressure categories for boilers, 3.82 MPa is considered medium pressure. The following are considered low pressure. The above can be considered high pressure. Among them, 5.3 MPa is considered medium-high pressure. The high-pressure ones are all around 10.0 MPa. There is also ultra-high pressure. Steam grades vary depending on the specific plant, as determined manually. Relatively.
It is each project that determines these standards on its own, by drawing on past experience; there is no unified standard yet. However, each generally has a range of values, and steam that falls within that range is considered to be the corresponding XX steam!
The captive heat power plants of power stations and chemical plants are also different. Our on-site power plant generates 3.5 kilograms of medium-pressure steam through a medium-pressure header, which is used for oil refining
The criteria for classifying the power industry and the chemical industry are different. In the power industry, 13.7 MPa is considered ultra-high pressure, 9.8 MPa is considered high pressure, 3.8 MPa is considered medium pressure, and pressures below 2.5 MPa are considered low pressure. In the chemical industry, around 10 MPa is considered ultra-high pressure, around 4.0 MPa is considered high pressure, around 1.2 MPa is considered medium pressure, and around 0.5 MPa is considered low pressure
