Process Heating

Many industrial facilities use process heating, for a variety of operations. Direct process heating (not including steam systems) accounts for about one-fourth of total industrial energy use. Opportunities to improve efficiency in this area include:

  • Optimize burner air to fuel ratios
  • Maintain clean heat transfer surfaces
  • Install furnace pressure controllers
  • Install waste heat recovery systems
  • Preheat combustion air
  • Reduce air infiltration in furnaces
  • Reduce radiation losses from heating equipment

DOE's Advanced Manufacturing Office offers a free process heating assessment and survey tool (PHAST) to identify the most cost-effective options for improving process heating.
