Suction pressure of the condensing system in the thermal power plant:
Thread Content
Suction pressure of the condensing system in the thermal power plant: The suction steam in the condensing system of the thermal power plant was originally used for primary extraction; can it now be changed to secondary extraction? Now both higher and lower steam pressures are required; for example, both 2 MPa and 1 MPa are needed.
1. Turbine units all have several stages of extraction steam; the pressure decreases from front to back. In most cases, the extraction steam is not adjustable. For any condensing unit, there is at least one pressure level at which the amount of extraction steam is the highest. Some larger condensing units have two stages of adjustable extraction steam, and the extraction pressure for these adjustable stages can be adjusted within a range of two kilograms. The amount of extraction steam can also be adjusted, though this is determined when the turbine is specified. 2. If extraction steam at different pressure levels is required, this can be achieved by reducing temperature and pressure, or through the use of pressure matchers, namely steam injectors. In the situation you described, as long as the turbine pressure is higher than the pressure required by the process, it is possible to achieve the desired outcome
