Patterson, R., J. Long, R. Parker, AND S. Calvert. EFFECTS OF CONDITIONING AGENTS ON EMISSIONS FROM COAL-FIRED BOILERS: TEST REPORT NO. 2. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-79/104B.
Description:
The report gives results of a field performance test of an electrostatic precipitator (ESP) which uses Apollo Chemical Co.'s LPA 445 and LAC 51B flue gas conditioning agents. The ESP is at an electric utility power plant, burning approximately 1% to 2% sulfur coal. Tests were conducted with and without injection of the conditioning agents. ESP performance was characterized in terms of particle collection efficiency and the chemical composition of particulate and gaseous emissions. Fly ash resistivity and dust opacity were also measured. Measurements show that there was no significant change in overall efficiency (99.6%) between the conditioned and unconditioned tests. There was some evidence that the conditioning agents reduced entrainment during electrode rapping and possibly improved the fractional efficiency slightly for particles smaller than about 5 micrometers in diameter.
