Abstract
Premixed hydrocarbon–air flames stabilized on Meker burners are proposed for use as reference sources of ultraviolet (uv) light. A measure for the uv light intensity output is given by the flame chemi-ionization. The ratio of optical energy output per unit of electrical charge generated is a function of the wavelength band of the flame emission spectrum but is independent of size of the flame, applied electric field required for measuring flame ionization, burner–electrode configuration, temperature, and of small fluctuations of pressure and composition of the hydrocarbon fuel. An approximate, average value of 8 · 10−3 J/C was determined for the 2000–2100-Å spectral band of a stoichiometric, premixed methane–air flame.
