THE CLAMOND GAS BURNER.
[Illustration: THE CLAMOND GAS BURNER.]
In this burner, which is a French invention, the light is produced by
burning ordinary coal gas within a basket of magnesia, which is
thereby brought to a high state of incandescence, and from which a
white, steady light is radiated. It may be said to consist of three
different parts. The first and inner part is a central column, B, of
fireproof material. The second part consists of two concentric
cylinders placed round the inner column and communicating one with the
other through the cross cuts, J. The third part is a china cup
inclosing the other parts, and perforated with a number of holes. The
gas burns in two different places. From A it passes directly through
B, at the top of which it branches off through tubes to an annular
chamber, D, from which it escapes through the openings, _a_, _a_, _a_,
where combustion takes place. The other combustion occurs within the
circular space, G, I, between the column and the inner of the two
surrounding cylinders, through two channels, E E, in the lower part of
the central column. The gas passes into a circular chamber, F F, and
escapes through small holes in the upper partition of this chamber,
where it burns.
