Boiler Chemistry Control and Treatment of Feed Water

Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers. Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT).

How it Works: Water for Power Plant Cooling | Union

2013-7-15·In power plants, lower efficiencies mean more fuel is needed per unit of electricity, which can in turn lead to higher air pollution and environmental impacts from mining, processing, and transporting the fuel. In 2000, most US dry-cooling installations were in smaller power plants, most commonly in natural gas combined-cycle power plants.

US4288979A - Combined cycle power plant

A combined cycle power plant incorporating a coal gasifier as the energy source. The gases leaving the coal gasifier pass through a liquid couplant heat exchanger before being used to drive a gas turbine. The exhaust gases of the gas turbine are used to generate both high pressure and low pressure steam for driving a steam turbine, before being exhausted to the atmosphere.

Boiler | Engaged in Thermodynamics

Heat Recovery Steam Generators are widely used in power plants and cogeneration/combined cycle systems. In the combined power cycle, hot exhaust gas from a gas turbine is fed into a HRSG to generate steam which in turn drives a steam turbine. There are four main components in an HRSG: the evaporator, superheater, economizer, and water pre-heater.
