The report covers basic and applied studies concerned with three Limestone Injection Multistage Burner (LIMB) process objectives: (1) avoiding degradation of collection efficiency in the electrostatic precipitator (ESP) during LIMB, (2) achieving satisfactory sulfur dioxide (SO2) removal, and (3) disposing of LIMB waste products. Tests were performed on Southern Research Institute's (SRI's) pilot scale combustor and on the full scale operating ESP at the Edgewater plant. SRI's testing coincided with the Edgewater LIMB demonstration, and significant test results were incorporated into the demonstration to enable the demonstration to meet its goals. The use of low-level spray humidification was found adequate to restore clear stack conditions which had severely deteriorated under LIMB without humidification. Water spray was also required for the enhancement of SO2 capture. Analytical data gathered on the waste product appears to confirm the acceptability of disposal in a landfill. There is also a report on the preliminary evaluation of the Advanced Silicate process, concluding that the process offers potential for greatly enhancing SO2 removal in connection with LIMB but cautions that substantial increase in entrained solids has to be considered.
