บทคัดย่อ (EN): PCC preheating temperature, batch size, and secondary airsupply. The experimental results showed that increasing the preheating temperature of theprimary combustion chamber and the batch size tend to accelerate the rate of volatile gasrelease, causing a "bottleneck effect" in the secondary combustion chamber and hence anegative effect on the overall performance of the incinerator. The optimum operatingcondition for the range of experiments tested appears to be a batch size of 5 kg and a primarychamberpreheating temperature in the vicinity of 700?C. The results from this study willserve as the starting point to examine the effect of the secondary air supply rate on theoperation of the secondary combustion chamber. Increasing the secondary air supplyenhanced the mixing performance between volatile combustion gas and secondary air result indecrease of CO yield and increase of 0 2 level at SCC exit. However, the production of NOand SO2 under the range of experiments seem to be not evident on increasing of secondaryair supply. According to there is inconsistency in each batch of waste feed with respect toheating values and moisture contents. Thus a fixed amount of secondary air supply can not beapplied through out the operations to maintain the performance of incinerator. Oxygenanalyzer to monitor the oxygen concentration in the combustion gas from secondarycombustion chamber is proposed to help ensure that adequate oxygen is available for propercombustion. Moreover in this study use numerical simulation to investigate the flow pattern inthe secondary combustion chamber, a detailed insight in the mixing process as well as thetemperature distribution, turbulence intensity and mean residence time. Optimization theoperating condition and alternative design is obtained by utilizing CFD. Reasonableagreements are achieved between numerical prediction and experiment.
