| Abstract | The report describes laboratory- and pilot-scale studies of the Limestone Injection Multistage Burners (LIMB) process as well as preliminary on-site tests at Ohio Edison's Edgewater Station. The effects of LIMB on electrostatic precipitation (ESP) performance are reported in terms of ash resistivity, electrical operation, mass loading, particle size distribution, and mass emissions. A significant reduction in SOx and NOx emissions from coal-fired utility boilers may require retrofit applications of emission control technology. LIMB is such a retrofit technology which may be applicable to a number of existing boilers. EPA's LIMB demonstration at Edgewater Unit 4 employs a wall-fired boiler of 105 MW electric generating capacity, equipped with a large ESP (nominal SCA 600 sq ft/1000 acfm at 528,000 acfm) of modern design that was retrofitted in 1982. |
