Industrial gases and heat recovery

Industrial gases of combustion processes or hot exhaust gas have a high potential to be recovered. Decisive are temperature as well as volume flow of the exhaust gas. As higher these values are, the more energy can be recovered.
Weather the heat can be used completely depends on the utilizable medium.
An example: If water from the heating system is supposed to be heated from 70°C (158°F) to 90°C (194°F), more energy can be used as in the production of 450°C (842°F) steam.
