10 tips that can be used to educate plant and facility managers on how to maximize boiler performance:
1.Maintain, Maintain, Maintain – following manufacturer recommendations on annual boiler maintenance is the easiest way to ensure the boiler will continue to run efficiently.
2. Proper Water Treatment – if water treatment is not done correctly, you will see a loss in heat transfer ability due to particulates clogging up internal boiler tubes. A deaerator can be used in most applications to increase water temperature and remove most of the particulates from the water.
3.Install a High Turndown Burner – this will increase energy savings by reducing on/of cycles.
4.Add Variable-Speed Drive Controls – installing these controls on the boiler feed pumps will enable a 5. motor to operate only at the required speed at any given moment and save energy by allowing an operator to fine-tune the system to run at optimal conditions.
6.Incorporate Parallel Positioning – doing so will allow the burner to maintain excess air levels more precisely and the boiler to run at its most capable efficiency point.
7. Include O2 Trim – adding an oxygen sensor/transmitter in the exhaust gas will maintain peak efficiency by minimizing excess air and optimize the air-to-fuel ratio.
8. Integrate Lead/Lag – this enables boilers to operate in sync with fluctuating steam loads by sequencing the operation of multiple boilers and matching system load.
9. Incorporate an Economizer – incorporating heat recovery into a boiler system will improve efficiency, and an economizer can increase efficiency up to 8 percent. Depending on the boiler type, fuel used and operating conditions, a standard or condensing economizer can be installed.
10. Recover and Repurpose Heat from Blowdown – you can do this one of two ways; by installing a blowdown heat recovery unit or a flash economizer. Both will capture heat and reuse it, with typical payback seen in less than a year.
Use Exchangers to Preheat Inlet Water – similar to a blowdown heat recovery unit, an exchanger can be added to preheat a boiler feedwater system or deaerator.
