The chemical treatment of flue gases to reduce polluting emissions was subjected to quantitative field tests to verify its practicality as a possible economic solution to current energy and pollution problems for electric utilities. Chemical conditioning agents for the ash in the flue gas of low sulfur coal fired units have been used to improve electrostatic precipitator collection efficiency by 50 to 90 percent, so that the units complied with emission regulations. Some units have been able to operate at increased capacity while still meeting compliance levels. Chemical neutralization of SO/sub 3/ in the flue gas, resulting in a lowered acid dew point, allows operation at reduced exit gas temperatures. Reduced particulate emissions frequently result from this safe change in operation.
