Microscale combustion: Technology development and fundamental research

Applied Catalysis A--General (特集 触媒研究と学術雑誌/情報)

A review of research and development on micro and mesoscale combustion is presented, with an emphasis on fundamental understandings achieved in the field during the last decade. Due to its small scale nature, increasing effects of flame–wall interaction and molecular diffusion are the characteristic features of micro and mesoscale combustion. After brief review of device developments, overview of fundamentals in micro and mesoscale combustion as well as possible future directions is presented.

A review on microcombustion: Fundamentals, devices and applications

The present invention is a method, and an apparatus for practicing the method, that creates a product stream and a heat of reaction from a fuel-rich fuel/air mixture and then contacts the product stream with a sufficient quantity of additional air to completely combust all of the fuel, to which air a portion of the heat of reaction has been transferred.

Catalytic combustion over platinum group catalysts: fuel-lean versus fuel-rich operation

A catalytic firebox reactor (10) employing an exothermic catalytic reaction channel (60) and multiple cooling conduits (20) for creating a partially reacted fuel/oxidant mixture. An oxidation catalyst (50) is disposed on the walls forming the boundary between the multiple cooling conduits (20) and the exothermic catalytic reaction channel (60), on the side walls facing the exothermic catalytic reaction channel. This configuration allows the oxidation catalyst to be backside cooled by any fluid passing through the cooling conduits. The heat of reaction is added to both the fluid in the exothermic catalytic reaction channel and the fluid passing through the cooling conduits. After discharge of the fluids from the exothermic catalytic reaction channel, the fluids mix to create a single combined flow. A further innovation in the reactor incorporates geometric changes (15) in the exothermic catalytic reaction channel to provide streamwise variations of the velocity of the fluids in the reactor.
