In some systems, like Sulphur Recovery Units (SRUs), waste heat boilers are considered the weak link; however, Exchanger Industries has manufactured waste heat boilers that have been in service for over 20 years without needing replacement or extensive maintenance.
Creare delivered a heat exchanger that was installed to recover waste heat from the exhaust gas of a RR-250 gas turbine engine. Water circulating through a loop picked up the waste heat from the exhaust gas heat exchanger and delivered the heat to an Electratherm Power+ Generator that produced almost 50 kW of electrical power. Waste Heat Recovery - Alfa Laval - heat transfer A key component in waste heat recovery is the heat exchanger. The profitability of an investment in waste heat recovery depends heavily on the efficiency of heat exchangers and their associated life cycle costs (purchase, maintenance, etc).
