Industrial Energy Saving Tips

All Combustion Systems

• Operate furnaces and boilers at or close to design capacity.
• Reduce excess air used for combustion.
• Clean heat transfer surfaces.
• Reduce radiation losses from openings.
• Use proper furnace or boiler insulation to reduce wall heat losses.
• Adequately insulate air or water-cooled surfaces exposed to the furnace environment and lines leaving the boiler.
• Install air preheat or other heat recovery equipment.

Steam Generation Systems

• Insulate all steam and return lines, flanges, valves and unions
• Improve water treatment to minimize boiler blowdown.
• Optimize deaerator vent rate.
• Repair steam leaks.
• Minimize vented steam.
• Implement effective steam trap maintenance program.
• Use high-pressure condensate to make low-pressure steam.
• Utilize backpressure turbine instead of pressure-reducing or release valves.
• Optimize condensate recovery.

Process Heating Systems

• Minimize air leakage into the furnace by sealing openings.
• Maintain proper, slightly positive furnace pressure.
• Reduce weight of or eliminate material handling fixtures.
• Modify the furnace system or use a separate heating system to recover furnace exhaust gas heat.
• Recover part of the furnace exhaust heat for use in lower-temperature processes.
