Air Compressor for Power Generation Industry

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 in power plants are commonly used 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 in thermal power plants are used 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. Several types of air compressors 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 power plants across India, Africa, the United Arab Emirates, and the Middle East. The ELGi power plant compressors 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 in power plants ensure a steady air supply and are durable enough 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

An air compressor is essential as it provides 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

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

Safe Operations

ELGi 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:

ELGi 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.

APPLICATION OF AIR COMPRESSOR IN POWER GENERATION

Air compressors are key components in many phases of power generation, serving as the workhorse for a variety of critical operations. They are the unseen heroes who quietly contribute to the flawless operation of power plants and, ultimately, the electricity that powers our lives. Let's take a closer look into the diverse roles of air compressors for power generation and their essential contributions in the power generation industry.

Starting and Stopping Power Plant Engines

Large engines in gas and diesel power plants are started with powerful air compressors. Compressed air is fed into the cylinders to generate the initial force required to crank the engine and start the combustion process. This ensures a reliable and efficient start-up, particularly for large engines that would not move on their own.

Operating Pneumatic Control Systems

Several valves, actuators, and dampers control the flow of fluids, gases, and fuel throughout the power production process. These elements are frequently powered by compressed air, and air compressors give the consistent pressure required for accurate control and efficient power generation.

Instrument Air and Plant Air Systems

Power plants require clean, dry, and oil-free compressed air for operating sensitive instruments and equipment. This "instrument air" in power plants is essential for monitoring and managing characteristics such as pressure, temperature, and flow rates. Furthermore, power plant air compressor systems supply compressed air for common applications such as powering cleaning tools, ventilation systems, and safety equipment.

Fuel Gas Boosting

In natural gas power plants, air compressors can be used to boost the pressure of incoming gas before it enters the combustion turbines. This increases the efficiency of the power generation process by allowing the turbines to extract more energy from the fuel.

Ash Handling and Emissions Control

As a byproduct, coal-fired power plants produce a substantial amount of ash. Air compressors are typically employed in pneumatic conveying systems to transport and dispose of this ash. They can also be employed in pollution control systems such as flue gas desulfurisation and nitrogen oxide (NOx) reduction, where compressed air aids in injecting chemicals and the optimisation of the cleaning process.

Maintenance and Repair

Air compressors are used in thermal power plants for maintenance and repair tasks. They power pneumatic tools like drills, wrenches, and sandblasters, enabling technicians to perform various tasks efficiently. Additionally, they can be used for cleaning equipment and components, ensuring optimal performance and extending their lifespan.

These are just some of the many applications of air compressors in power generation. Their versatility and reliability make them indispensable components in ensuring the smooth operation and efficiency of power plants, ultimately contributing to a stable and reliable electricity supply for our ever-growing needs.
