Supercritical steam generator - Wikipedia

2019-10-24 · A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.Therefore, liquid water immediately becomes steam.

Supercritical fluid - Wikipedia

2019-10-27 · A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist.It can effuse through solids like a gas, and dissolve materials like a liquid. In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical

Steam Pressure Reduction: Opportunities and Issues

2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

ANALYSIS OF EFFICIENCY AT A THERMAL POWER PLANT

2016-4-23 · The three main components of a thermal power plant are boiler, turbine and alternator. Hence, the overall thermal power plant efficiency depends on the efficiencies of these three components. The thermal efficiency is an indication of how well the plant is being operated as compared to the design characteristics. 2.1 Boiler Efficiency Calculation
