Abstract

The effect of high ash coal which has relatively high ash content and low combustibility on unburned carbon and NOx emission was experimentally investigated at several excess air ratio and particle size conditions of four coals containing different ash content in a drop tube furnace. Flue gas was measured by Gas analyzer in order to figure out unburned carbon characteristics. The results show that the higher content of ash makes the higher unburned carbon rate, subsequent changes in NOx emission characteristics was investigated.
