How can one determine whether a condensing steam turbine has high or low power output?
The enthalpy values corresponding to exhaust pressure and temperature, as well as the power generation capacity of the unit, can all be used as references.
It is primarily measured by the power generation capacity of the unit! ! ! ! ! ! ! ! !
Using enthalpy values to express this might involve complex calculations; in such cases, formulas and parameters need to be used. Simply put, comparison is necessary – for a power unit, this means comparing the actual operating parameters with the rated parameters to see whether the actual values can meet or approach the theoretical design values. In the case of power plants, when the designed power output is the same and the steam parameters are identical, the unit that uses less steam will produce more work. The same principle applies to turbine units in chemical plants: different loads require different amounts of steam and different steam parameters. In any case, energy is conserved
The lower the exhaust pressure and temperature, the higher the utilization rate of steam and the more work can be produced. Of course, the material of the condenser also needs to be taken into consideration.
