LIMB demonstration project extension and Coolside demonstration: A DOE assessment
The goal of the US Department of Energy (DOE) Clean Coal Technology (CCT) program is to furnish the energy marketplace with a number of advanced, more efficient, and environmentally responsible coal utilization technologies through demonstration projects. These projects seek to establish the commercial feasibility of the most promising advanced coal technologies that have already reached the proof-of-concept stage. This document serves as a DOE post-project assessment of the CCT Round 1 project ``LIMB Demonstration Project Extension and Coolside Demonstration'', described in a report to Congress (Babcock and Wilcox 1987), a paper by DePero et al. (1992), and in a report by Goots et al. (1992). The original limestone injection multistage burner (LIMB) demonstration work was conducted by Babcock and Wilcox Company (B and W) beginning in 1984, under the sponsorship of the US Environmental Protection Agency (EPA) and the State of Ohio Coal Development Office (OCDO). In 1987, B and W and the Ohio Edison Company agreed to extend the full-scale demonstration of LIMB technology under the sponsorship of DOE through its CCT Program, and with support from OCDO and Consolidation Coal Company, now known as CONSOL. In a separate effort, CONSOL had been developing another flue gas desulfurization (FGD) technology known as the Coolside process. Both LIMB and Coolside use sorbent injection to remove SO{sub 2}. The LIMB process injects the sorbent into the furnace and the Coolside injects the sorbent into the flue gas duct. In addition, LIMB uses low-NO{sub x} burners to reduce NO{sub x} emissions; hence it is categorized as a combination SO{sub 2}/NO{sub x} control technology. To take advantage of synergism between the two processes, the CCT project was structured to incorporate demonstration of both the LIMB and Coolside processes. Coolside testing was accomplished between July 1989 and February 1990, and the LIMB Extension test program was conducted between April 1990 and August 1991. The host site for both tests was the 105 MWe coal-fired Unit 4 at Ohio Edison's Edgewater Station in Lorain, Ohio. The major performance objectives of this project were successfully achieved, with SO{sub 2} emissions reductions of up to 70% demonstrated in both processes.
