Cement manufacturing is a highly energy-intensive process. Given the fragile and dynamic nature of the fuel and power situation faced by cement plants today, it makes sense for them to adopt waste heat recovery-based solution for the following reasons:
- Greater energy security – helps meet up to 35% of power requirement
- Improved competitive positioning
- Regulatory push – policies mandating use of minimum 5-10% renewable/WHR energy are already in place in several states
The source of waste heat in the cement plant is after the suspension pre-heaters downstream of the rotary kilns and the clinker coolers.
