The sizes of scrap tires used in the study were 10-20mm and 50-100mm . The cross section of the combustion chamber is 0.7 by 1.4m and 2 m in height. The freeboard section is 1 m in diameter, 4 m in height. There are two levels of secondary air injection. each level has four equally-spaced air nozzles. The special arrange- ment is non-equal air plenums of the windbox and incline distri- butor causing the internally circulating within the fluidized bed. The typical operating conditions were as flollows: the feed rate of scrap tires was kept about 65 kg/ hr, static bed depth was approximately 0.35 m, superfical gas velocity was 0.84 m/s and the average bed temperature was about 800℃. The typical start-up procedure takes 4-5 hrs. The effect of the size of waste tire, secondaryu air flow rate and tertiary air flow rate on the combustion efficiency, sulfur retention and pollants emission were studied. According to the experimental results, the emissions of SO2、NOx and CO in the flue gas meet the ROC-EPA regulations. Chyang, Chien Song 錢建嵩 1993 學位論文 ; thesis 114 zh-TW |
