What is the role of cooling towers and heat exchangers in power plants?

Cooling towers and heat exchangers are essential in power plants for regulating temperatures. Cooling towers cool circulating water, reducing the temperature of processes, while heat exchangers transfer heat from one medium to another, often recovering waste heat from gas turbines or other plant equipment to improve energy efficiency.

What types of cooling towers are used in power plants?

Power plants use various types of cooling towers, including natural draft and mechanical draft towers. Mechanical draft towers can be either induced draft (counter-flow) or cross-flow, each optimised for different cooling capacities and environmental conditions.

How do heat exchangers enhance power plant efficiency?

Heat exchangers recover heat from exhaust gases and other sources, enabling power plants to recycle energy that would otherwise be wasted. This not only improves overall plant efficiency but also reduces fuel consumption and emissions, making the operation more environmentally friendly.

What maintenance services are necessary for cooling towers and heat exchangers?

Regular maintenance of cooling towers and heat exchangers is crucial for optimal performance. This includes cleaning, inspecting components for wear and tear, replacing parts such as fans and fill material, and monitoring for corrosion or scaling. Engineering services also ensure that equipment meets industry standards and operates efficiently.

Which companies provide cooling towers and heat exchangers for power plants?

Leading suppliers include companies that specialise in industrial cooling technologies, such as SPX Cooling Technologies, Hamon, and Kelvion. These companies offer a range of solutions, from turnkey cooling tower systems to custom-built heat exchangers, along with engineering, repair, and maintenance services.
