Thermal power plants are the major contributors of electricity to India's national power system.
The production of power is a water-intensive process. In 2019, the Government withdrew around 36.5 billion cubic meters of water to meet the electricity demands of 1.33 billion people. Thermal power generation uses steam generated by the combustion of oil, liquefied natural gas (LNG), coal, and other materials to turn turbines and generate electricity. Because it can flexibly adjust to the varied ways in which power is consumed (demand variations) as production gets higher, this sort of generation plays a critical role in delivering electricity.
Water is used in a thermal power plant (TPP) for a variety of functions, including the boiler, cooling system, and coal and ash management systems, with the cooling system accounting for the majority of the volume. Water treatment systems are critical for guaranteeing plant stability. Where a considerable amount of steam is required, water treatment equipment’s such as saltwater desalination systems and condensate demineralizers are placed in thermal power plants. Water is also required in the industrial sector, particularly in the manufacture of goods.
How does thermal power plant work?
The heat energy gained from the burning of solid fuels (mainly coal) is utilized in thermal power plants to turn water into steam, which is at high pressure and temperature.
This steam is utilized to turn the turbine blades, which are linked to the generator by a shaft. The generator of power plant converts the kinetic energy of the turbine impeller into electric energy.
What is Water Treatment Systems in Thermal Power Plants?
A thermal power plant's lifeblood is water. Thermal power facilities use water treatment to avoid issues including carryover to turbine components, as well as corrosion and scale formation/deposition in the boiler and turbine systems. So obtaining clean and pure makeup water and dealing with wastewater has been a requirement since the first stream generating unit went into operation.
Water travels through the main water system of power plants, first as condensate, then boiler feed-water, boiler water (in the boiler), steam (in the turbine), and ultimately back to condensate. Make-up water is used to compensate for the water lost during circulation.
Other water-related systems include:
(1) Make-up water treatment system to supply highly-purified water obtained after the treatment of raw water such as industrial water,
(2) Chemical dosing and water quality monitoring systems to monitor and adjust water quality for corrosion prevention,
(3) Condensate treatment systems are used to filter circulating water in a plant (mostly in once-through boilers), and
(4) Wastewater treatment systems to purify wastewater from devices and components of thermal power plant facilities.
Individual plant water includes lot of pollutants, which are expelled. To increase water quality to an acceptable level for release into public water regions, such contaminants are removed in stages at water treatment systems.
Handling of water used in thermal power plants is becoming increasingly complex. Fortunately recent advances which includes reverse osmosis, membrane bio-reactors and forward osmosis membrane can help.
