For a back-pressure turbine, what are the factors that affect the back pressure?
Back pressure is mainly controlled by holding back. When connected to the system, the pressure remains constant and changes along with the system.
Steam inlet pressure and outlet pipeline network pressure of the turbine.
It should mainly be regulated by the export system
There are two factors: 1. Backflow system pressure； ⒉Turbine exhaust outlet valve opening.
It mainly refers to the consumption of steam from the pipeline network on the backside; of course, it also includes the pressure and quality of the medium-pressure steam supplied from outside.
This is mainly determined by the power and speed of the turbine; the outlet pressure of the turbine is slightly higher than the pressure in the outlet pipeline network.
