A Bunsen Burner for Acetylene.—An interesting item regarding the use of acetylene as a heating agent occurs in the Chemical News. A. E. Munby writes: "The cheap production of calcium carbide has placed a powerful illuminant within the reach of those who possess no gas supply, but so far little has been heard of the use of acetylene as a heating agent. Our laboratory is, so far as we know, the first to make use of the gas for this purpose. We employ a Bunsen burner of special dimensions, the tube being five millimetres in internal diameter. A slightly wider tube may be used, provided the mouth be curved inward, so that the actual exit does not exceed the diameter mentioned; if larger, the flame tends to strike down. The gas jet is very small, being only capable of delivering about one cubic foot of acetylene per hour under six inches water pressure, such a rate of consumption giving an ordinary working flame. The air holes and collar are arranged as in an ordinary Bunsen, the exact size of the former not being of much importance, provided they be large enough to admit the air required. A generator capable of giving gas under seven inches water pressure with the full number of burners in use is required. The heating effect of the flame is, of course, very great, enabling one to dispense with the blowpipe for some operations, such as small fusions. . . . It would seem that in practice, for equal volumes burned, the acetylene has nearly twice the heating power of coal gas."
