Steam Generator Parameter Index

- Nov 30, 2018 -

Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc.


Boiler capacity can be expressed in terms of rated evaporation or maximum continuous evaporation. Rated evaporation is the amount of steam continuously produced per unit time at a specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum amount of steam that can be continuously produced per unit time at a specified outlet pressure and temperature. The unit of evaporation is customarily expressed in tons per hour, and the capacity of a power station boiler can also be expressed by the electric power (megawatts) of the associated turbine generator.


Steam parameter

The steam parameters include the steam pressure and temperature of the boiler, usually the superheated steam pressure and temperature at the superheater, reheater outlet, and the absence of superheater and reheater, ie the saturated steam pressure and temperature at the boiler outlet. The boiler pressure unit is expressed in megapascals (MPa) and is also expressed in terms of engineering atmospheric pressure (at), which is equal to 10.2 engineering atmospheric pressure.


Feed water temperature

Refers to the inlet water temperature of the economizer. When there is no economizer, it refers to the inlet water temperature of the drum.
