The characteristics and stability of the hydrogen diffusion flame have been investigated as for a clean energy in the future. The objective of the present study is to get further understanding lifting/blow-off of the hydrogen diffusion flame and present clearer understandings of the processes for flame holding. The species of the fuels are the pure hydrogen and the dilute hydrogen which is formed with putting nitrogen gas into the fuel of hydrogen. The parameters of the experiment are selected as fuel velocity, co-flowing air velocity, equivalent ratio, nozzle inner diameter, concentration of the fuel and so on. The stability limit and flame behaviors are investigated with increasing the spout fuel velocity or the co-flowing air velocity. The inside temperatures of the flame are measured for researching the structure of the flame.
