Public Service Electric and Gas (PSE and G) is evaluating the effectiveness of post-combustion NO{sub x} reduction technologies on a wet-bottomed, coal-fired utility boiler. The technologies under study are conventional urea-based SNCR, in-duct and air heater SCR, and a combination of SNCR and SCR. While SNCR and, to a limited extent, SCR have been used on coal-fired boilers, these processes have not been demonstrated on a unit with the same configuration as the wet-bottom, continuous slagging, pulverized coal furnaces operated at PSE and G`s Mercer Generating Station. This paper summarizes the results of the three programs and comparisons to baseline NO{sub x}. Of particular interest was the relationship of each technology to operation of the unit. The ability to maintain low NO{sub x} emissions while varying loads and fuels, as well as determining ammonia slip and pressure drop was also demonstrated.
