Abstract |
The report gives results of an investigation of advanced NOx control techniques on a pilot scale test facility firing pulverized coal. The 440 kW pilot scale test facility can simulate front wall, opposed, or tangentially fired utility and industrial boilers. Baseline and control technology tests were performed on three coal types over a range of parameters. Baseline NO levels closely simulated full scale results in both levels and trends over these parameters. The primary control technology investigated was staging. First- and second-stage parameters investigated include stoichiometry, excess air, temperature, mixing, residence time, and coal composition. The most important first-stage parameters were stoichiometry and residence time. A minimum NO level was achieved at a stoichiometric ratio between 0.75 and 0.85, depending on fuel and furnace configuration. The first-stage residence time was also found to be critical: the longer first-stage residence times gave lower stack NO levels. To obtain NO levels below 150 ppm, first-stage residence times of up to 3 seconds were required. Second-stage parameters were found to be of second-order importance. |
