High Temperature And High Pressure Steam Turbine
The pressure is between 10-25MPa, and the temperature is between 500-600℃. The parameters of high temperature and high pressure steam turbine mainly include the following aspects:
1, steam inlet pressure: high temperature and high pressure steam turbines need to have a high enough steam inlet pressure, generally between 10-25MPa.
2, steam inlet temperature: high temperature and high pressure steam turbines need to withstand high temperature and high pressure working environment, so it is necessary to have a high enough steam inlet temperature, generally between 500-600℃.
3, speed: high temperature and high pressure steam turbine needs to have a high enough speed to meet the needs of high power output. Under normal circumstances, the speed of high temperature and high pressure steam turbines is between 3000-5000rpm.

The cycle efficiency of high temperature and high pressure steam turbine parameters The cycle efficiency of high temperature and high pressure steam turbine refers to the ratio of the power generated per unit fuel to the calorific value of the unit fuel. High temperature and high pressure steam turbines have the characteristics of high cycle efficiency, which is mainly due to the following factors:
1. The high temperature steam turbine makes the steam working at high temperature and high pressure directly enter the steam turbine, without too much work in the boiler, reducing the heat loss.
2. Reasonable design of turbine impeller and guide vane reduces heat loss
3. Under high temperature and high pressure conditions, steam is highly expanded through the turbine to release energy more fully.
4. Reasonable turbine system design and thermal cycle optimization improve the utilization efficiency of heat energy.
