Blau Water Gas for Industrial Purposes. A. MEADE. (J.

Gas Lighting, cxvii, 83.)--The industrial use of water gas has made considerable progress on the continent of Europe. Its most important property is its very high flame temperature. With preheated air, a temperature above the melting-point of platinum is reached, and under ordinary conditions the hottest part of the flame is between 28oo ° and 3ooo ° F. Burned at a pressure of ~ pound per square inch, with air at 2~ pounds, in a fire clay faced burner, it is used for pipe welding. For heating purposes it is unnecessary to purify it from hydrogen sulphide, but this must be done for lighting and. power purposes. Blau water gas is not very suitable for gas engines, as it contains so much hydrogen that it cannot be highly compressed. With suitable appliances the results obtained for incandescence lighting are equal or superior to those obtained with ordinary coal gas. It is also used for the preparation of hydrogen by liquefying or freezing out the other constituents, and bv cement manufacturers to heat their rotary furnaces.
