Sources of Waste Heat

Some of the market sectors with attractiveness for waste heat recovery include:

  • Gas pipeline compressor stations
  • Oil and gas extraction
  • Petroleum and coal products manufacturing
  • Cement plants
  • Chemical plants
  • Ethanol plants
  • Pulp and paper mills
  • Steel and metal manufacturing and refineries

  • Artificial synthetic fibers, rubber, and resin manufacturing

At a particular industrial site, some of the potential sources of waste heat include:

  • Boilers
  • Process heaters
  • Furnaces, ovens, or kilns
  • Flares
  • Conductive, convective, and radiative losses from hot equipment surfaces
  • Conductive, convective, and radiative losses from heated product streams
  • Hot combustion gases otherwise discharged to the atmosphere
  • Natural gas pipeline compressor
  • Other natural gas-fired turbines or oil-fired turbines
  • Reciprocating engine exhaust
  • Cooling water from furnaces , air compressors, and internal combustion engines
