Here's an analysis of the market based on applications (Preheating and Steam & Electricity Generation) and end-use industries:

Applications of Waste Heat Recovery Systems:

  • Preheating: Waste heat recovery systems are widely used for preheating applications in industrial processes. By capturing and utilizing waste heat from exhaust gases or process streams, these systems preheat incoming air, water, or other fluids required for subsequent process stages. Preheating helps improve process efficiency, reduce energy consumption, and lower fuel costs in industries such as petroleum refining, metal production, and chemical processing.
  • Steam & Electricity Generation: Waste heat recovery systems play a crucial role in steam and electricity generation applications. Heat recovered from industrial processes is used to generate steam, which can then be utilized for various purposes, including power generation, heating, and mechanical work. Additionally, waste heat can be converted into electricity through technologies such as organic Rankine cycle (ORC) systems or steam turbines. This electricity can either be used onsite to supplement power needs or exported to the grid, providing additional revenue streams for industrial facilities.

End-Use Industries:

  • Petroleum Refining: Waste heat recovery systems are extensively used in petroleum refining processes to capture and utilize heat from various sources such as flue gases, catalytic crackers, and distillation columns. Recovered heat is utilized for preheating feedstocks, generating steam, and powering turbines, thereby improving energy efficiency and reducing greenhouse gas emissions in the refining industry.
  • Metal Production: In metal production processes such as iron and steel manufacturing, waste heat recovery systems are employed to capture heat from furnaces, kilns, and other equipment. Recovered heat is utilized for preheating raw materials, heating combustion air, and generating steam, contributing to energy savings and process optimization in the metal production sector.
  • Cement: Waste heat recovery systems are increasingly being integrated into cement manufacturing plants to capture waste heat from kiln exhaust gases and clinker coolers. Recovered heat is utilized for preheating raw materials and drying fuels, resulting in reduced energy consumption and lower production costs in the cement industry.
  • Chemicals: Waste heat recovery systems play a vital role in chemical processing plants, where heat is recovered from various process streams such as reactors, distillation columns, and drying operations. Recovered heat is utilized for steam generation, process heating, and power generation, enhancing energy efficiency and reducing operating costs in the chemical industry.
  • Pulp & Paper: Waste heat recovery systems are utilized in pulp and paper mills to capture heat from pulp digesters, dryers, and recovery boilers. Recovered heat is utilized for preheating water, generating steam, and powering turbines, improving energy efficiency and reducing environmental impact in the pulp and paper industry.
