Solved: 10-77: Consider A Cogeneration Power Plant Modifie

10-77: Consider a cogeneration power plant modified with regeneration. Steam enters the turbine at 9 MPa and 400C and expands to a pressure of 1.6 MPa. At this pressure, 35 percent of the steam is extracted from the turbine, and the remainder expands to 10 kPa. Part of the extracted steam is used to heat the feedwater in an open feedwater heater.

Boiler and Condenser Pressures - Rankine Cycle

The thermal power plants are currently designed to operate on the supercritical Rankine cycle (i.e. with steam pressures exceeding the critical pressure of water 22.1 MPa, and turbine inlet temperatures exceeding 600 °C). Supercritical fossil fuel power plants, that are operated at supercritical pressure, have efficiencies around 43%.

Coatings | Free Full-Text | An Overview on Corrosion

In most WTE plants, the boiler steam conditions of 300–450 °C/2.9–5.8 MPa are adopted to avoid the severe corrosion damages on boiler tubes and hot parts, while, in biomass power generation plants, the steam conditions are higher than WTE plants, and can be up to 540 °C/12 MPa …
