The DOE LIMB Demonstration Project Extension is a continuation of the EPA Limestone Injection Multistage Burner (LIMB) Demonstration. EPA ultimately expects to show that LIMB is a low cost control technology capable of producing moderate SO{sub x} and NO{sub x} control (50--60 percent) with applicability for retrofit to the major portion of the existing coal-fired boiler population. The current EPA Wall-Fired LIMB Demonstration is a four-year project that includes design and installation of a LIMB system at the 105-MW Unit 4 boiler at Ohio Edison's Edgewater Station in Lorain, Ohio. LIMB Extension testing continued during the quarter with lignosulfonated hydrated lime, pulverized limestone, and hydrated dolomitic lime while firing 1.8% and 3% sulfur coals. Sulfur dioxide removal efficiencies were equivalent to the results found during EPA, base LIMB testing. Sulfur dioxide removal efficiencies were lower than expected while testing with pulverized limestone without humidification. A slight increase in sulfur capture was noted while injecting pulverized limestone at the 187' elevation and with the humidifier outlet temperature at 145{degree}F.
