Waste Heat Recovery Boiler (WHRB)
Capture high-temperature process exhaust and convert it into steam — without extra fuel firing.
Steam from heat you already have
A waste heat recovery boiler (WHRB) sits in the exhaust path of process equipment — DRI kilns, cement lines, furnaces, coke ovens, gas turbines and similar sources — and generates steam without a dedicated fired furnace. GrandeH engineers pressure parts and heat-transfer surfaces for the gas temperature, dust loading and steam demand of each plant.
How a WHRB works
- Heat source — hot flue gases from furnaces, kilns, turbines or process equipment enter the WHRB
- Heat transfer — energy moves through engineered surfaces into circulating water in pressure parts
- Steam generation — recovered heat converts feedwater into steam for process, headers or turbines
Applications
- Steel & DRI — kiln / cooler exhaust steam generation
- Cement — preheater and cooler gas heat recovery
- Power — HRSG-style recovery on turbine exhaust
- Glass, coke oven, chemical, incineration and non-ferrous metal plants
