Waste Heat Recovery (WHR) is a technology which captures waste heat energy and delivers it as useful energy where it is needed and with the required parameters. It can provide the heat for an industrial process or for space heating. As its source is waste energy, it is practically free of cost.
There are multiple benefits of waste heat recovery such as reduced energy costs, primary energy savings, reduced environmental impact and carbon emissions.
Waste heat sources
Waste heat may be present not only in several industrial processes and applications, but also in some residential/commercial buildings. The most common sources of waste heat suitable for cost-effective heat recovery are: ventilation systems extract, boiler and furnaces flue gases, air compressors…
Manufacturing industries. Waste heat is abundant in manufacturing industries. Starting from the most obvious – industries with furnaces such as metal foundries, glass melting factories, etc. – to any factory with a chimney stack or a boiler.
Generators. Buildings whose electricity comes from generators have plenty of waste heat which can save the entire winter heating cost for the entire building or cooling during the summer.
The waste heat recovered from a genset can be in the form of hot water of up to 90 degrees or steam of up to 8 bar of pressure (in some cases we can reach higher pressures). It can also be transformed into cooling energy thanks to absorption chiller.
Waste heat technology
Recovering energy that is already available on a site today is the pure expression of energy efficiency. The technologies available are different and must be evaluated with accuracy, using the know-how of companies with expertise and experience to maximize both the benefit of the enterprise and the environment. Termogamma® provides its customers with all the expertise and know-how needed to carry out, from the feasibility analysis and sizing steps, up to their maintenance (suggested: training for self maintenance), the installation of this type of systems.
