Waste heat boiler for sulfur recovery unit
Ceramic Ferrules For Waste Heat Boilers | Tech Ceramic
The waste heat boiler (WHB) is arguably the most fragile part of an sulfur recovery unit (SRU) and is subject to sudden and very costly failure. The most common failure is the tube to tubesheet joint where temperature can become unacceptably high, causing the welds to fracture and the joints to fail.

Case study: Extend tube life in a waste heat boiler
The sulfur recovery unit (SRU) separates sulfur from sulfur compounds. Within the SRU, a waste heat boiler (WHB) produces high-pressure steam, using the heat generated in this process. Since it operates in a high-temperature, high-hydrogen sulfide (H2S) environment, the WHB tube is often corroded by

HEAT RECOVERY BOILERS - thermopedia.com
The convective elements of boilers fired by municipal industrial or other waste materials are often referred to as heat recovery boilers although, apart from their geometry, they are more akin to the rear end of a furnace-fired boiler. Perhaps the most common heat recovery boiler is now the gas turbine heat recovery boiler.
