Compressed air is also known as the fourth utility and finds application in various processes in power plants, such as in coal handling and operating pneumatic instruments. Air compressors help run several components in a power plant, such as boilers, turbines, generators, precipitators, and ash handling systems. There are different types of power plants based on power generation, such as nuclear power plants, solar thermal power plants, geothermal power plants, and wind power plants. Air compressors are commonly used in power plants to supply compressed air for various purposes. In a fossil fuel power plant, compressed air may be used to operate pneumatic valves and actuators, to start and stop diesel engines, and to power tools and equipment. In a nuclear power plant, compressed air may be used for emergency shutdown systems, to operate control rod drive mechanisms, and to power tools and equipment. Compressed air may also be used for ventilation and air conditioning in power plants. A power plant requires a compressed air system for generating instrument air that is high-quality and contaminant-free. Service air is the other kind of compressed air used in power plants, used for cleaning, purging filters, and ash transportation.

ELGi AIR COMPRESSORS IN THERMAL POWER PLANTS

Air compressors are used in thermal power plants to supply compressed air for a variety of purposes, such as operating pneumatic controls, starting and running auxiliaries, and providing air for combustion in the furnace. In a coal-fired power plant, for example, air compressors may be used to start the coal mills, oil pumps, and air preheaters. There are several types of air compressors that may be used in a thermal power plant, including reciprocating compressors, screw compressors, and centrifugal compressors. The type of compressor chosen will depend on the specific requirements of the application, including the pressure and flow rate needed, as well as the availability of space and power.

ELGi oil-free air compressors are suitable for the power plants across India, Africa, United Arab Emirates and Middle East. The vast offerings from ELGi cater to thermal power plant’s demands by supplying superior quality instrument air that is oil or moisture free. The oil carryover can cause serious harm to the power plant applications. ELGi air compressors ensure steady air supply and are durable to withstand high temperatures and pressures in a thermal power plant.

WORKING PRINCIPLE OF AIR COMPRESSOR IN THERMAL POWER PLANTS

Air compressors are used in thermal power plants to supply compressed air for various purposes, such as operating pneumatic equipment, powering air tools, and providing forced ventilation. Air compressors are typically located in the auxiliary building of a power plant, where they can be easily accessed for maintenance and repair. It is important to maintain the air compressors in good working condition to ensure the reliable operation of the power plant.

The type of air compressor used in a thermal power plant depends on the specific requirements of the plant and the equipment it serves.

There are several air compressors, including reciprocating compressors, rotary screw compressors, and centrifugal compressors. In a reciprocating compressor, the compression of the air is achieved by using a piston that moves back and forth within a cylinder. The movement of the piston compresses the air, which is then delivered to the required equipment through a discharge valve.

In a rotary screw compressor, the compression of the air is achieved by using two intermeshing helical screws that rotate within a sealed chamber. The air is drawn into the chamber and then compressed as it moves through the screws.

In a centrifugal compressor, the compression of the air is achieved by using a spinning impeller to increase the velocity of the air. The high-velocity air is then directed into a diffuser, which slows the air down and increases the pressure.

BENEFITS OF ELGI AIR COMPRESSORS IN THERMAL POWER PLANTS

Air compressors are essential in thermal power plants, as they provide compressed air for the plant's operation. There are many benefits to using air compressors in thermal power plants, including the following:

Improved Efficiency:

Air compressors help improve the plant's efficiency by providing a constant supply of compressed air to power pneumatic tools. This can help increase productivity and reduce energy consumption.

Contaminant-Free Air:

Air compressors help reduce the emission of pollutants from the plant by providing a cleaner source of compressed air.

Safe Operations:

Air compressors help improve the plant's safety by providing a safe and reliable compressed air source. Pneumatic tools can be safer to use than electrical tools, as they do not produce sparks or generate heat.

Cost Efficient:

Air compressors help reduce the plant's costs by providing a cost-effective compressed air source. Pneumatic tools are typically more cost-effective than electrical motors, as they require less maintenance and have a longer lifespan.
