How Waste Heat Powers Heat Exchangers

Waste heat can be used to operate heat exchangers in several ways:

Preheating Feedwater

Waste heat recovery systems in power generation have the ability to pre-heat the feedwater that enters the boiler. Less energy is required to reach the target steam temperature when waste heat is used to raise the temperature of the incoming water, waste heat use to run shell and tube heat exchangers design and operation increasing overall efficiency.

Space Heating

Waste heat can be used to heat spaces in commercial and industrial environments. Heat can be transferred using heat exchangers from waste heat sources to a secondary fluid that is then pumped through the heating system of a building. As a result, less heating is required, which lowers energy expenses and consumption.

Steam Generation

Heat exchangers can also be used to produce steam from waste heat. After that, this steam can be employed in numerous industrial activities, such as power generating, heating, and turbine driving.

Cooling Applications

Particularly in air conditioning systems, waste heat can be used for cooling purposes. Heat-powered absorption chillers can cool buildings or industrial operations, which lessens the demand on conventional refrigeration systems.

Industrial Processes

Chemical reactions, drying, distillation, and other industrial processes can all benefit from the use of waste heat. These operations can become more economical and energy-efficient by absorbing and using waste heat.
