Abstract��By establishing the mathematical model of methane combustion in tubular chamber, the numerical simulation of temperature field, velocity field, flow field and mass of methane, oxygen, carbon dioxide and as well as oxy��nitride in reflux area of combustion chamber are carried on in this paper. By changing preheating temperature of entry hot��air, the distribution regularities of above mentioned variables were modeled numerically. The research results show that the reaction in the combustion chamber proceeded thoroughly, and temperature distribution much uniform when air preheating temperature was increased. These research results indicate that mathematical model established would be an efficient tool in mass analysis during design.
