flat-flame

A large lamp, owing to its higher illuminating efficiency, is better in this respect than a small one -- light for light, it is more hygienic than ordinary flat-flame coal-gas burners, while a small lamp is less hygienic.

It will therefore be understood at once, from what has already been said about the superiority on hygienic grounds of acetylene to flat-flame coal-gas lighting, that acetylene is in this respect far superior to petroleum lamps.

It should, moreover, be remembered that the ideal illuminating power of a gas is the highest realisable in any Argand or flat-flame burner, while the said burner may not be a practicable one for general use in house lighting.

There are, of course, endless modifications of flat-flame burners to be found on the markets, but only

The terminal pressure in the case of service-pipes must be settled, as mentioned in Chapter II., broadly according to the pressure at which the burners in use work best, and this is very different in the case of flat-flame burners for coal-gas and burners for acetylene.

The young man confessed that he had specimens of the best kinds of flat-flame burners in his pocket.

In the flat-flame burners there are differences in the internal arrangement.

M. Somzee also raises the illuminating power of an ordinary flat-flame burner by causing an obscure effluvium to traverse the dark portion of the flame.

By the arms on the chimney-frame the flame is broadened at the bottom, with a smaller dark space at the base than in any other flat-flame burner.

Neither of these devices singly gave a solution of the difficulty; but by combining the two -- the injector and the twin-flame principle -- the modern flat-flame acetylene burner has been evolved, and is now met with in two slightly different forms known as the Billwiller and the Naphey respectively.
