Boiler (power generation) - Wikiped

2019-6-10 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

The effect of a number of reheat stages on the ideal

The effect of a number of reheat stages on the ideal steam reheat cycle is to be studied. Repeat Problem 9.35 using two reheat stages, one at 1.2 MPa and the second at 0.2 MPa, instead of the single reheat stage at 0.8 MPa. Problem 9.35. A small power plant produces steam at 3 MPa, 600 C in the boiler.

Thermal power station - Wikipedi

: Calebe|2019-6-10 · A thermal power station is a power station in which heat energy is converted to electric power.In most of the places in the world the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

2017-10-20 · Consider a cogeneration power plant which is modified with reheat and which produces 3 MW of power and supplies 7 MW of process heat. Steam enters the high-pressure turbine at 8 MPaand 500 C and expands to a pressure of 1 MPa.At this pressure, part of the steam is extracted from the turbine and routed to the process heater, while the

A small power plant produces steam at 3 MPa, 600 C

A small power plant produces steam at 3 MPa, 600 C in the boiler. It keeps the condenser at 45 C by transfer of 10 MW out as heat transfer. The first turbine section expands to 500 kPa, and then flow is reheated followed by expansion in the low-pressure turbine. Find the reheat temperature so that the turbine output is saturated vapor.
