Waste Heat Recovery System - an overview | ScienceDirect .
The first step in planning to install a waste heat recovery system (WHRS) is to work out the net available waste heat that can be used to generate power. 2.1.1. In a cement plant, waste heat is available mainly from kiln exhaust gases and vent air from the clinker cooler. Waste heat is also available from the exhaust of diesel engines of DG Set.Get a Quote
