Manufacturing plants produce heat waste due to the following sources, where there is use of energy but is not completely harnessed. A large amount of heat can be generated from hot exhaust gases that emanate from various furnaces, kilns, ovens, and boilers. The heat produced is usually released by means of stacks or ventilators at a very high temperature which can be harnessed again.
Heat waste can be produced from cooling systems such as water cooled apparatus, compressors, and hydraulic machines. In spite of the fact that the purpose of these machines is to dissipate energy, they are capable of dissipating heat that is still useful and can be used for other purposes. The process produces heat waste that emanates from hot surfaces and cases of machinery, particularly in plants where metal working or heating takes place.
Steam systems can also produce heat waste because of heat losses that occur during steam condensation and through uninsulated pipes. Heat waste may also be produced by air ventilation in manufacturing plants as a result of production activities.
However, this energy is captured through waste heat recovery systems that use the energy for purposes such as pre-heating air, heating water, and even generating steam.
