air-gas

Since regeneration inside the chamber requires precautions against the formation of unwanted and dangerous air-gas mixtures and would require powerful fans, regeneration outside the chamber is usually preferred.

More commonly, however, air-gas is made non-automatically, or more or less automatically by the employment of some mechanical means.

Those results may be compared with those referring to air-gas, which emits in incandescent burners from 3.0 to 12.4 candles per cubic foot according to the amount of spirit added to the air and the temperature to which the gas is exposed.

Hence, if the apparatus for saturating air with the vapour of the light petroleum is placed well above all the points at which the air-gas is to be burnt --

In all respects the method of making carburetted acetylene is identical with that of making "air-gas," which was outlined in Chapter

Acetylene, the Principles of Its Generation and Use W. J. Atkinson Butterfield

Moreover, the odour of the acetylene itself would render the detection of a leak far easier with carburetted acetylene than with air-gas.

Acetylene, the Principles of Its Generation and Use W. J. Atkinson Butterfield

A current of naturally damp, or artificially moistened, air is led over or through a mass of calcium carbide, whereby the moisture is replaced by an equivalent quantity of acetylene; and this mixture of acetylene and air is carburetted by passing it through a vessel of petroleum spirit in the manner adopted with air-gas.

It is difficult to give reliable data as to the cost of air-gas, inclusive of the expenses of production.
