||The paper is a brief review of work planned and work underway in support of the Limestone Injection Multistage Burner (LIMB) development effort. A detailed description of the equipment used in the Innovative Furnace in-house effort is given. Work plans for contracts and a cooperative agreement with Acurex Corporation, Energy and Environmental Research Corporation, and Southern Research Institute covering internally staged burner work, fundamental combustion research, staged fuel NOx reduction, tangential-fired furnace pilot project, and LIMB particulate emissions are reviewed. The in-house work on limestone properties and reactivity and sorbent properties/fundamental chemistry is mentioned. The planned 'super sorbents' and graphite drop-tube furnace work are covered. No results are discussed. Mention is made of lime-based sorbents with surface area of over 60 sq m/g as measured by a B.E.T. unit using N2 as the absorbed gas. Tests on furnaces ranging in size from 2.9 W to 29 MW are planned. Particle size distributions of total furnace emissions, before control devices, in the 0.1 micrometer range are to be measured. Reduction of both SOx and NOx is one goal of the effort.
