The report gives test results on a coal-fired, overfeed, traveling-grate stoker. The boiler tested is rated at 45,000 lb/hr saturated steam at 140 psig. Measurements include gaseous emissions (O/sub 2/, CO/sub 2/, CO, NO, NO/sub 2/, SO/sub 3/, and HC), uncontrolled particulate mass loading, particle size distribution of the flyash, combustible content of the bottom ash and flyash, and boiler efficiency. Measurements were made at loads representing 50, 75, and 100% of design capacity, several excess air levels, and both high- and low-overfire air pressure settings. Increased overfire air pressures decreased particulate loading, CO, and HC. Particulate loading was 1.0 lb/million Btu under full-load high-overfire-air conditions. NO/sub x/ averaged 0.416 lb/million Btu (307 ppM) at full load.
