Abstract

The experimental apparatus of micro-space ignition and combustion are designed to investigate the size effects of micro-space ignition and combustion by reducing the sizes of the combustors with premixed hydrogen/air. The experimental results in the micro-space show that the smaller the ignitable hydrogen concentration range

the shorter the gas fuel residence time. When the sizes of the combustors decrease from centimeter scale down to millimeter scale

the heat transfer loss increases obviously due to the growing of the ratio of surface to volume and the stable combustion is difficult to maintain due to flame quenching. It is suggested to adopt hydrogen possessing low quenching distance and ignition energy associated with pressure

insulation and catalysts. The plate capacitor spark electrodes for micro-space combustion with cantilever beam structures are designed and fabricated by evaporation

where the gap between two spark electrodes gets more than 10 μm and the thickness less than 0.2 μm. Smaller capacitance of the electrode leads to a longer igniting time. Electroplating is proposed after evaporation to deposit in relatively large volumes for microfabrication

thus 4 μm thickness of the electrode is obtained with increased single discharge energy.
