Case Study 1 - Steel Plant – Incinerator

Waste Heat Recovery from hot gases exhausted by Incinerator in steel plant

System Description

Initial Situation

• Paint sludge incinerator exhausts large quantity of flue gases at high temperature to atmosphere

Challenges

• Reutilize the waste heat to fulfill heat energy requirements of the plant
• Design a system that can be retrofitted with the process plant

Solution Provided

• Waste Heat Recovery Boiler on incinerator exhaust gases
• Generation of steam for process use
• Smoke tube boiler with economizer
• Fully automatic pneumatically operated three way diverter valve helps in continuous operation without affecting incinerator furnace pressure
