Description:
The report gives results of a study undertaken as a preliminary program to provide data on the environmental effects of a chemical flyash conditioning agent (Apollo Chemicals conditioner LPA 402A). Both the emissions due to the chemical and its effect on electrostatic precipitator (ESP) performance were investigated. The tests were conducted over a 10-day period at Pennsylvania Power and Light Co.'s Montour Plant with the plant operating on high sulfur coal (without conditioner) and on low sulfur coal (with and without conditioner). Sulfur oxides (SOx), ammonia, organics, particulates, flyash resistivity, and ESP power supply values were measured during each test period. During conditioner injection, the low sulfur coal flyash resistivity was reduced about 60%, although the ESPs responded slowly to this change and its effect was not clearly evident during the test period. The results of the SOx, ammonia, and particulate measurements were inconclusive due both to insufficient precision for the number of field tests and to the effect of boiler transients. It is unlikely that the ESP will meet particulate standards when low sulfur coal is burned even if the conditioner is used under test conditions. The test provided useful background information for planning. More thorough testing at Montour seems warranted.
