Case Study 7 - Textile Industry

Waste Heat Recovery from hot gases exhausted by 6.5 MW Roll Royce gas engine generator

System Description

Initial Situation

• Gas Engine exhausts large quantities of high temperature gases to atmosphere
• Gas Engine Generator is used for power generation to fulfill requirements of the plant

Challenges

• Reutilize the waste heat to fulfill heat energy requirements of the plant
• Design the equipment for at least single suitable application.

Solution Provided

• Waste Heat Recovery Boiler on Engine Exhaust Gases
• Finned tube cross flow water tube boiler for generation of steam for process use
• Fully automatic pneumatically operated three way diverter valve for diverting the flue gases to the stack when steam is not required by the plant
