碩士 === 國立臺灣大學 === 機械工程學系 === 85 === The purpose of this thesis is to study the relations between inlet air and burning rate and exhaust gas. The main considerations include the total air, the air flow ratio of the undergrate to uppergrate, and the overgrate air position. The simulations of Kanruy, (1994)and Kuo, (1997) were used to derive the correlation of combustion rate as a function of flue gas temperature and oxygen concentration The results of experiments suggest that, combustion as the air flow ratio of the overgrate to undergrat is equal to 1/4 has higher burning rate and combustion temperature, rather than which as the ratio is equal to 1/2. Burning rate and combustion temperature are getting higher while the position of overgrate air is closer to the grate. The agreement between the model and the experiments is reasonable.
