• The boilers are capable of burning only natural gas (no oil backup), and • The boilers have a maximum design heat input capacity of 50 million BTU/hr or less. The MDEQ is seeking a reauthorization of air quality fees from the legislature in 2007. This reauthorization may continue the waiver for future years.

Example A boiler operates for 8,000 hours per year and consumes 500,000 MMBtu of natural gas while producing 45,000 lb/hr of 150 psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas less combustion air temperature of 400°F. From

flue gas is recirculated to the boiler. Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers, and boilers can typically operate at recirculation rates of 20-25 percent without adversely affecting boiler heat transfer and efficiency.
