    fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.Learn More

  • Improve Overall Operations by Conducting Boiler Maintenance

    Oct 29, 2021 · In addition, boiler performance will continue to deteriorate gradually. This wastes thousands of dollars in extra fuel as the boiler runs longer than needed to produce the heat. For example, if a 200-hp boiler operates 8,000 hours per year with a medium level of calcium scale, the boiler could lose 5 percent of its efficiency.Learn More

  • Waste Heat Recovery | TLV - A Steam Specialist Company

    Using a principle similar to economizers, waste heat boilers recover heat generated in furnaces or exothermic chemical reactions at industrial plants. These locations may contain significant energy that should not be wasted up a stack. Instead, this energy can be captured to generate low-to-medium pressure steam in a waste heat boiler (WHB).Learn More

  • Boiler Heat Exchanger and Sulphur Recovery Unit Information

    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. This level of performance is a testament to our focus on engineering and Learn More
