碩士 === 國立中興大學 === 機械工程學系 === 85 === Most of the appliance of domestic gas burners at present are classified toBusen burners. The peculiarity of the burner is to get primary air naturally with the high velocity gas of jet. The different demands lead to the necessa-rity of gas pressure, flame temperature, flame height, and the occurance of yellow tip or lifting flame for various burners are different. The researches and papers regarding this topic are very limited till now in our country. Depending on the auther''s knowledge, a large proportion manufacturers always design their work by their experience, and then modify them by try and error method. Now, we hope to have a series of basic research for this topic,and hope to promote gas combustion technology of our country. The purpose of this project is to find out the possible combustion state ofthe mixture of gas and air at burner ports, such as lifting flame, flash back,yellow tip and so on. We also want to find the reasons and determine the desi-rable ranges of domestic gas burner so as to be the accordance of future design.
