Waste gas heat recovery from air compressors

Waste gas heat recovery from air compressors is a technology that uses the heat energy from the exhaust gas generated by the work of the air compressor for energy recovery. The specific recovery process is as follows:

When an air compressor is in operation, high temperature and high pressure compressed gas is produced by compressing atmospheric air.

In this process, the heat energy in the air is transferred to the compressed gas.

Conventional air compressors typically vent the compressed gas to the atmosphere, resulting in the loss of heat energy in the exhaust gas.

Exhaust gas waste heat recovery technology works by capturing and utilising the heat energy in the exhaust gas and converting it into usable energy.

A common form of recovery is through a heat exchanger. A heat exchanger transfers the heat energy from the exhaust gas to a medium that needs to be heated, such as water or air.

In a heat exchanger, the exhaust gas and the medium flow through separate channels, but there is heat transfer between them.

The exhaust gas releases some of the heat energy that allows the medium to be heated, which is then used for some other heat requirement, such as heating water or air.

With waste gas heat recovery technology, the heat energy in the exhaust gas of an air compressor can be utilised to the maximum extent possible, resulting in an efficient use of energy. This not only reduces energy consumption and operating costs, but also helps to reduce the demand for other energy sources and therefore the environmental impact.
