A QuickTip from Maxon, A Honeywell Company
Mitigate rising fuel costs by inspecting burners and combustion heating systems to identify potential efficiency gains.
ADJUSTMENTBurners can be stable and reliable even when misadjusted, but proper air/gas ratio reduces fuel consumption.MAINTENANCEPeriodically inspect burners for wear, excessive oxidation, or warping. Check gas nozzles, mixing plates, and bluff bodies; clean or replace air filters. Inspect control devices for proper settings and function.FIRING METHODConvert indirect fired processes to direct fired for possible 5-20% efficiency gains and reduced thermal loss in stacks and piping.
CONTROL METHODPrecision temperature control eliminates temperature overshoots. Retrofitting to modulating burners can reduce gas usage.CONTROL DYNAMICSCorrectly tuned control loops eliminate “hunting” which wastes energy and adds wear on actuators and valves.RECUPERATION AND REGENERATIONSave fuel by transferring stack energy to combustion air. Regenerative systems alternately store and recuperate heat from exhaust gases.BLOWERSVariable frequency drives can provide electrical savings. Maintaining blowers and cleaning filters will maximize efficiency.BURNER SELECTIONSelect burners tailored for your process. This can dramatically affect fuel usage.BURNER SIZINGDon’t install a burner that’s larger than the process demands. AUTOMATION Intelligent controls save fuel and reduce emissions by monitoring ratios and providing automatic adjustment. Outstanding reliability and uptime can combine for an impressive ROI .
No one can predict the future of fuel prices. Examine your combustion systems today to locate opportunities for savings.
