PROCESS BOILER COMBUSTION UPGRADES
General Requirements: Only natural gas equipment is eligible for incentives. Boilers fueled by electric, propane, or oil are NOT eligible for incentives. Redundant or backup boilers do not qualify. PROCESS BOILER COMBUSTION UPGRADES Requirements: • Complete Table G of the “Process Systems Incentive Catalog Supplemental Data Sheet” for this measure. • Incentives are available for process boilers only where the boiler is used to provide a hot water or steam load to a process end use. For boilers that are used for HVAC space heating, use the boiler combustion upgrade measures in the HVAC/Plumbing Incentive Catalog. • Boiler must be natural gas-fired, forced draft that operates a minimum of 2,000 hours per year. • Installation of redundant or backup boiler combustion equipment does not qualify for an incentive. • Boiler input must be entered in boiler horsepower (BHP). 1 BHP = 33.476 MBh. • High turndown burner must be able to provide efficient combustion at a 10:1 turndown ratio or greater. The turndown ratio must be clearly shown on a manufacturer’s spec sheet or similar documentation. • High turndown burner incentives (PS4760 and PS5238) are eligible on boilers ≤ 1,000 BHP. Boilers > 1,000 BHP may be eligible for custom incentives. • Invoices must be attached and include the manufacturer name and model number of linkageless controls, O2 trim, and high turndown burner equipment.

CUSTOM PROJECT IDEA Talk to your Energy Advisor about custom incentives that may be available for installing boiler stack economizers which can also increase the efficiency of the boilers as well as provide a heat source of incoming make-up water.
