FY 1974 report. Study on hydrogen combustion technology; 1974 nendo suiso nensho gijutsu ni kansuru kenkyu hokokusho

Abstract

In the use of hydrogen as fuel, there is the problem on NOx emission. The amount of NOx emission is not as much as in the use of coal or oil, but is more than in the use of natural gas or town gas. However, it can be said that hydrogen is an ideal fuel if considered that it does not emit other air pollutants such as CO, HC and soot/dust which are usually associated with hydrocarbon base gas fuels, and also that hydrogen forms a circulation system which is ecologically sound. The flame of hydrogen is non-luminous, but the flame temperature is high. The formation of NOx depends strongly upon the flame temperature, and therefore, in the design of hydrogen burner, it is necessary to well mix it with air and to avoid the production of the local high temperature region. Further, when using hydrogen to large boiler, the combustion technology to control NOx reduction is needed. About the hydrogen flame, the matter to be noticed is an experimental result that NOx reduction was observed by adding trace ammonia to hydrogen gas. If this method can be successful, NOx can be reduced with no increase in fuel consumption. It  More>>
