The paper gives an overview of EPA's Limestone Injection with Multistage Burners (LIMB) program, a program for research, development, and demonstration of cost-effective emissions control technology for coal-fired boilers that can reduce both sulfur oxides (SOx) and nitrogen oxides (NOx). The LIMB concept uses low-NOx burners plus sorbent injection to control these pollutants simultaneously. LIMB technology represents a lower-cost alternative to currently available SOx control approaches such as flue-gas desulfurization, coal cleaning, and coal switching. LIMB technology is especially attractive where coal-fired boilers must be retrofitted to minimize emissions of NOx and SOx, which are major acid-rain precursors. This is due to LIMB's relative ease of retrofit to both small and large coal-fired boilers and its lower cost. LIMB performance goals are: (for retrofit) to achieve a 50-60% reduction of both SOx and NOx from uncontrolled levels; and (for new units) to achieve a 70-80% reduction of NOx and a 70-90% reduction of SOx from uncontrolled levels.
