The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.

Many thousands of industrial plants around the world generate high-pressure steam for process applications and power generation. Yet, water/steam monitoring and control often take a back seat to process operations, even though corrosion, scaling and other problems caused by poor water/steam chemistry can cost a plant millions of dollars.
Other Power Plant Valve Links. Steam Converting Valves - The conversion of superheated high pressure steam into steam at lower temperatures and pressures is a common practice in process industries. This technology is also used in power stations to utilize the steam energy leaving the turbine for other purposes (e. g. for heating).
Dry-cooling systems use air instead of water to cool the steam exiting a turbine. Dry-cooled systems use no water and can decrease total power plant water consumption by more than 90 percent. The tradeoffs to these water savings are higher costs and lower efficiencies.
Large steam power generators provide the majority of the electric power. Steam turbines are ideal for very large power configurations used in power plants because of their higher efficiencies and lower costs. In a power plant, the steam turbine is attached to a generator to produce electrical power.

The steam-electric power station is a power station in which the electric generator 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.The greatest variation in the design of steam-electric power plants is due to the different fuel sources.
Power plants that use a steam turbine to produce electricity are categorized according to the source and use of the steam. Nuclear, coal, combined cycle, cogeneration, and some solar power plants use steam cycles in order to produce power.
This is the first geothermal power plant to be managed by PNOC-EDC. It is one of 20 projects that will be implemented during the 2006-2014 timeframe. The construction work included the FCRS, steam supply development, steam turbine, generator, substation, and transmission lines.
Dec 28, 2018· A power plant's job is to release this chemical energy as heat, use the heat to drive a spinning machine called a turbine, and then use the turbine to power a generator (electricity making machine). Power plants can make so much energy because they burn huge amounts of fuel—and every single bit of that fuel is packed full of power.
