Facility Issues
Measure and manage ventilation
Reexamine your gas contract.
Minimize surplus combustion air
in theplant. Use an economizer to optimize outside airuse. Replace warped or worn outside airdampers.
Considerrenegotiating terms to gain lower rates withutilities.
bytuning damper settings on boiler draft fans,installing over-fire draft control systems, sealingdoors, etc. Excess air in the combustionchamber contributes to heat loss via fluegas escape.
Operations
Potential gain in furnace efficiency of 1%when air and oxygen content are reduced
by 15% and 1.5%, respectively
Equipment Maintenance
Inspect and recalibrate thermocouples
Install removable insulation
Inspect steam distribution systems forleaks and repair where necessary.
Regularly clean strainers
in furnaces to obtain more accurate zonetemperature measurements and help increasefurnace efficiency.
onuninsulated valves, pipes, and fittings to reducelosses in the process heat distribution system.
Possible sources of unnoticed leaks includepiping, valves, process equipment, steam traps,flanges, and seals.
upstream ofsteam traps to prevent particle accumulation.Excessive deposition can hasten the need forrepair or replacement.
Potential energy savings of 2-5%
Potential energy savings of up to 5%
Potential boiler efficiency gains of 10-15%
Lower the water temperature in boilers
Rework schedule
to reduce short-cycle loss as well as convectiveand radiant heat loss.
of processing operations(e.g., lessen the frequency of mixed and/orpartial loads) to reduce delays and reheatrequirements.
Potential boiler efficiency gains of 1%
Potential gains in boiler efficiency
of 10-12%
when the stack gas temperature is
decreased by 40°F
Prevent scale accumulation by ensuringwater treatment systems are operating effectively.Scale build-up in boiler feedwater tubes inhibitsboth throughput and heat transfer.
Cutting your natural gasbill can be as simple asadjusting a dial.
Get started with some ofthese simple, low-cost steps,and be sure to encourageactive worker involvement.You may also want to consideradditional measures, such asa plant-wide assessmentavailable through theU.S. Department of Energy’sBest Practices program.

After formalizing steam trap inspections, Velsicol ChemicalCorporation reduced annual energy use at its Chestertown,
MD, plant by 27.3 trillion Btu–a 17% decrease. The project paidfor itself in 2.5 months and achieved yearly financial savings of $80,000.
The Chestertown facility has two boilers with over 300 steam traps and annually produces 25,000 tons of chemicals.
