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 …
