Waste Heat Recovery - Energy

Process gas from the waste heat boiler is cooled down further to 130℃ in the primary stage condenser, where the sulfur stream is condensed and separated flowing to the sulfur pool. 2nd level condensing. The process gas from the primary condenser is heated up to 260-290℃ by the waste heat of the gas and comes into the primary reactor where the sulfur stream is produced by the further reaction.

Factors Affecting Claus Waste Heat Boiler Design and Operation

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

Top Five Fundamental Integrity Issues for SRU Waste Heat

A primary objective in designing a boiler is to provide for the greatest possible efficiency in absorption of heat. Other objectives are production of pure steam and safe, reliable operation. Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces

Waste heat recovery - Alfa Laval

A Sulphur Recovery Unit (SRU) suffered an unplanned shutdown triggered by flame failure following an internal leakage in a reaction furnace waste heat boiler (WHB). The resulting loss of SRU capacity forced a shutdown of one gas oil hydrotreater and reduced throughput at two more gas oil hydrotreaters. If another of the SRUs had been off-

Waste Heat Boiler - an overview | ScienceDirect Topics

A waste heat boiler captures byproduct heat from other processes and uses it to create steam. The steam can promote thermal integration by heating other fluids or drive electricity-producing turbines. Waste heat boilers offer an effective means of recycling thermal energy, and since byproduct heat is often lost to the atmosphere this translates directly into reduced fuel consumption, lower GHG
