Abstract
Nitric oxide (NO) reduction process by reburning with two kinds of biomasses corn straw, rice husk and one pulverized bituminous coal were studied in an isothermal high temperature drop tube furnace (DTF). Experimental studies were performed on influences of NO removal efficiency by fuel type, excess air ratio (SR), resident time, and reburning fuel fraction. Meanwhile, burnout of three reburning fuels was analyzed. The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time. Beyond this resident time limit, NO removal efficiency increase slowly. In the tested conditions, biomass was more efficient than pulverized bituminous coal for NO removal efficiency and unburnt carbon in fly ash was within reasonable limits.
