Waste heat recovery boilers

A waste heat recovery boiler (WHRB) produces steam from the waste heat of flue or process gases, without additional fuel, cutting the plant's energy costs.

A WHRB (Waste Heat Recovery Boiler) is a steam generator that uses the waste heat of exhaust gases from industrial processes to produce saturated steam. It is designed to make maximum use of the available heat, reduce primary fuel consumption and raise the overall energy efficiency of the plant. Thanks to its robust construction and adaptable design, it integrates into various processes with available hot process or flue gases.

Operating principle

Hot exhaust or process gases pass through the boiler tube bundle and transfer their heat to the water in the pressure shell. The water heats up and evaporates, producing saturated steam. The steam separates in the steam space and is led to the consumers, while the cooled gases go on to the chimney or the next parts of the system. Continuous feeding with chemically treated water ensures safe operation, a stable water level and a long service life.
