EPA (Environmental Protection Agency) LIMB (Limestone Injection Multistage Burner) Development and Demonstration Program Status Report (April 1985)

摘要

The report summarizes the technical status of EPA's Limestone Injection Multistage Burner (LIMB) program and discusses the planned program leading to commercialization by 1990. It provides a background on the emissions of SO2 and NOx from coal-fired utility boilers and discusses critical aspects of the LIMB process. It also provides an overview of the LIMB process and the program approach, followed by a detailed discussion of results and plans for each major technical area of the program. The goal of the LIMB program is to provide a low cost technology for control of SO2 and NOx for coal-fired boilers. In the U.S., the dominant source of SO2 is existing coal-fired utility boilers, which also contribute about 20% of the total NOx emissions. LIMB is one emerging technology which has the potential to accomplish this goal in a more cost effective manner than currently commercial technologies.
