| 中文摘要 | a novel miniature cylindrical combustor, whose chamber wall is made of porous material, has been designed and experimented for reducing heat loss and enhancing flame stability. the combustor has the function of reducing wall heat loss, extending residence time and avoiding radical chemical quenching with a self-thermal insulation concept in which heat loss reduction is obtained by the opposite flow directions between thermal energy transfer and mass flow. the methane/air mixture flames formed in the chamber are blue and tubular in shape. between the flames and the porous wall, there is a thin unburned film that plays a significant role in reducing the flames' heat loss and keeping the flames stable. the porous wall temperature was 150-400 degrees c when the temperatures of the flames and exhaust gas were more than 1200 degrees c. when the equivalence ratio phi < 1.0, the methane conversion ratio was above 95%; the combustion efficiency was near 90%; and the overall sidewall heat loss was less than 15% in the 1.53 cm(3) chamber. moreover, its combustion efficiency is stable in a wider combustion load (input power) range. |
