Combustion Stabilization of Gas Burners

Abstract

Natural gas is a fuel that is expected to be supplied stably in the long term, and it is expected for the achievement of the low carbon society because of the least amount of carbon dioxide formation per unit calorific value in the hydrocarbon fuels. In this article, we introduce various burners and the latest trend of them that use gas fuels based on natural gas from the viewpoint of the combustion stability. Gas burners have some features. The degree of freedom of the flame shape is big, and gas burners have a wide variety. It is easy to obtain steady combustion and the automatic control of the ignition and the extinction. The blockage of the burner by the dirt and the wear-out rarely happen, and the emission of unburnt spieces and the soot is basically small, and the combustor efficiency is high with a little excessive air. Therefore, it is used for various fields such as industrial use, business uses, and the household uses. In the future, there will be a possibility that the zero emission will come true by achieving super-low NOx and CCS (CO₂ Capture and Storage) by using the oxygen burning.
