Prevention of PCDD/PCDF Formation by Coal Co-Firing

摘要

In this work, experiments were conducted in a large, pilot-scale unit which is astate-of-the-art facility with fuel handling and combustion release rates representative of large field units. The effect of coal co-firing was studied for two types of municipal-waste-based solid fuels. Tests were conducted over a range of process variables (e.g., calcium hydroxide (Ca(OH)2) injection, HCl concentration, flue gas temperature, quench, and resistance time) so that the results could have implications for a wide variety of waste combustors.
