Carbon Monoxide

Carbon monoxide (CO) is formed due to incomplete combustion of waste in the furnace. The quantity of CO formed depends on the combustion temperature, available combustion air, amount of turbulence and the amount of time the exhaust gas remains in the burner. The amount of CO formed during combustion can be minimized by adjusting the above parameters.

At the Resource Recovery Facility, the waste feed rate and the overfire/underfire combustion air are controlled to maintain the above parameters at optimum levels. In addition, the combustion temperature is generally maintained at 2000 °F or higher (the permit requires a minimum combustion temperature of 1800 °F) to ensure near-complete combustion of waste, thus minimizing CO.

The CO levels in the stack plume have generally been less than 30 parts per million (ppmv), compared to the permit level of 200 ppmv, averaged for 1 hour, 100 ppmv averaged for 4 hours, or 50 ppmv averaged over 24 hours.
