A resource I recommend often is the Industrial Technologies Program (ITP), which is a part of the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy. With our 10 tips issue in mind, I consulted this helpful source. According to the ITP, implementing these tips can reduce your energy use by up to 25 percent.

  • Insulate oven walls and doors well enough to minimize heat losses and help keep temperatures low on the equipment’s outer walls.
  • Wherever you can, reduce or eliminate water-cooled parts inside the oven. If cooled parts are necessary, insulate them well to reduce heat transfer to them.
  • Control makeup air to keep it at the minimum value required to meet process and equipment safety requirements.
  • Reduce or eliminate openings in the oven walls and doors to minimize heat losses and prevent cooler ambient air from leaking into the heated enclosure.
  • Use pressure controls with fired or electrically heated ovens to minimize air leaks into the equipment, or hot gas leaks from it.
  • Use automatic controls to regulate the air-fuel ratio and minimize excess air for burners at all firing rates, while ensuring that there are no excess unburned hydrocarbons such as carbon monoxide, hydrogen, methane or soot in the exhaust gases.
  • Clean heat transfer surfaces frequently to maintain high heat transfer efficiency in heat exchangers and other systems that use electrical heating elements, coils, radiant tubes, etc.
  • Consider recovering heat from exhaust or flue gases to heat air, water and oils, or preheat incoming material.
  • Consider preheating the combustion air by using a recuperator or a regenerator to recover the heat of the exhaust gases from the oven
  • Use efficient operating practices: Operate the heating equipment at close to full load or design load capacity, avoid delays between cycles, and minimize the weight of load supports such as fixtures, trays and baskets.
