WASTE HEAT RECOVERY - thermopedia.com

Waste heat can be considered as either low grade (<100°C), medium grade (100°C–400°C) or high grade (>400°C). Low grade waste heat can only be recovered effectively when there is a high quantity of waste heat and a ready use for it. There are many examples of successful heat recovery projects for temperatures between 100°C and 200°C.

What is Waste Heat Recovery? (with picture)

Waste heat is the thermal energy which is commonly discarded after being created as a byproduct of industrial processes and working machinery of all kinds, including domestic appliances and cars. The recovery of waste heat can be carried out in a number of different ways, but techniques are limited by the need to be cost-effective in order to be commercially viable.
