Thermal power station - Wikipedia

2021-1-9 · A thermal power station is a power station in which heat energy is converted to electric power.In most, a steam-driven turbine converts heat to mechanical power as an intermediate to electrical power. Water is heated, turns into steam and drives a steam turbine which drives an electrical generator.After it passes through the turbine the steam is condensed in a condenser and recycled to

What is the purpose of deaerator in steam power

The deaerator is an essential equipment in Steam based power plant, where boiler is to be operated. The presence of oxygen, and other non-condensable gases, in the feed water is a major cause of corrosion in the feed water piping, boiler, and condensate piping line. The dissolved oxygen content of the feed water is a major factor of corrosion

Mercury as a Working Fluid. - Douglas Self

2019-8-19 · MERCURY Mercury has got to be the ultimate dodgy working fluid mercury: as remarked elsewhere on this site, in the Steamwheel gallery, (where mercury is used as a weight and sealant rather than a working fluid) it is an insidious poison of a most unpleasant kind. It has a much higher boiling point than water, at 357 degC.

Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

pHORP | Yokogawa China Co., Ltd.

Power plant boiler houses designed to burn coal or high sulfur oil are required by Federal and State pollution regulations to "scrub" (remove) sulfur dioxide from flue gasses to meet emission limits. SO 2 in flue gasses is known to be harmful to the environment, as it is one contributor to the formation of acid rain. pH control is critical for the proper functioning of the scrubber system.
