The Claus Waste Heat Boiler (WHB) is a critical piece of equipment in a Sulphur Recovery Unit (SRU); its fundamental purpose is as a heat transfer device used in energy recovery. Sulphur plant operators have recently been experiencing higher than normal WHB failure rates, perhaps from oxygen enrichment and pushing rates.
A waste heat boiler uses the heat formed as a by-product of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid.
A waste heat recovery unit/heat exchanger recovers heat from hot streams, water or gasses, that still have a relatively high energy content which would otherwise go unused into the atmosphere. The most common examples are from steam from cooling towers or flue gases from a heat source such as a diesel generator.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.
