Numerical Investigation into Premixed Combustion of the Micro Porous Media Combustor
摘要
Abstract
A micro porous media combustor with the special recuperative jacket is developed and its combustion performances including the influences of combustion power and excess air ratio on exhaust gas temperature, combustion efficiency, external wall temperature and heat loss ratio of the micro combustor are numerically investigated. The results show that the designed micro combustor has some merits such as high combustion efficiency and low heat loss ratio in the wider operating range. Moreover, wall temperature and heat loss ratio reduce contrarily with the increasing of combustion thermal power and excess air ratio. The optimal combustion power of the micro porous media combustor is 200 Watt and the corresponding excess air ratio should be between 2.5 and 3.0. By analyzing further the temperature fields of the micro combustor, it is indicated that due to adopting the special structure of recuperative jacket and opposite direction inlet mode of reaction gas through porous media plates, flow direction of reaction gas is just against that of heat loss released from the micro combustor and part of heat lost can be recovered to increase the enthalpy of reacting gas in the recuperative jacket and porous media. As a result, combustion efficiency is enhanced and heat loss from the micro combustor to the external environment is obviously reduced. The micro porous mediam combustor is a high-efficiency and low-heat-loss micro combustion.关键词
