Systems of energy recovery are usually installed in manufacturing plants, industrial ovens, thermal oxidizers, boilers, dryers, and many other kinds of equipment that produce a lot of thermal energy losses. In accordance with particular applications, recovered thermal energy may be used for heating of fresh air, process fluids, combustion, or heating within production process.

Among the advantages of such systems is increased energy efficiency, reduction of expenses, and decreased fuel consumption. Recovery of thermal energy helps businesses decrease the environmental impact of its operations and make the best of its energy resources.

Before installing any thermal energy recovery system, manufacturers have to evaluate exhaust gas temperature, volume of air, operating schedules, degree of contamination, and demand for recovered heat.

Dust, corrosion, and deposition can affect the efficiency of heat transfer and therefore regular inspections and cleaning should be done. Through proper system design and maintenance, heat recovery systems can increase the efficiency of operations, help achieve sustainable development goals, and save money for the organization.
