dc.description.abstractCirculating Fluidized Bed Incinerator is known to be one of the best available options for treating medical waste, particularly the pathological related waste. A proper operation of the incinerator is essential to ensure complete destruction of the waste. The combustion efficiency (one of the performance indicators) of the CFB incinerator is determined by the presence of carbon monoxide and carbon dioxide emission. In this regard, a study to investigate the relationship between variables affecting the combustion efficiency, namely temperatures, air pressure and air pollution control devices were performed using excel. Results showed that waste, combustion temperatures, air pressure and air pollution control devices contribute significantly to the combustion efficiency of the process. Two variables were used; inlet air flow rate and inlet liquid flow rate. The maximum and minimum liquid to gas ratio were between 1.9 l/m3 and 0.6 l/m3. The pressure was constant along riser. The maximum pressure drop of the CFB was 490 kPa. The combustion temperature was ranging between 700 and 970 , the constant temperature along the riser was observed when inlet air flow rate was 12 m/s. high temperature reduction was observed at heat exchanger from 350 to 90 . Approximately 75% of the flue gas heat energy was absorbed by cooling liquid; the maximum heat transfer in the heat exchanger was 60 kW. The pH of water used as scrubbing solution was changing from 6.68 to 5.57 and 6.88 to 5.72 for wet scrubber Stage 1 and 2 respectively, and the pH of 6 g/l lime concentration was changing from 12 to 6 for both stages. The combustion efficiency of the CFB with assistance of multistage wet scrubber was 99.6 %.en_US
