'certain new and useful lm provements in Gas- Firing, of which the following is a specification.
' This invention relates to a method of'firing in which hydrogen, water-vapor, andoxygen or air are burned. These three gases are separately introduced into the fire-chamber, so that the water-vapor neutralizes the wellknown injurious effect of the pointed-cone flame foundin hydrogen firings. At the same time the vapor is to preventthe explosion liable to occur with oxyhydrogengas. gas used is pure hydrogen, which receives the oxygen necessary for combustion either from the air or from a direct supply of oxygen when the air is-cut off.- If desired, the oxygen may also be supplied in addition to an air-supply. In all cases, however, water-vapor under the lowest possible pressure is used, which is admitted simultaneously with the oxygen in such a manner that the hydrogen and oxygen are only brought into contact with one another after they have been mixed with the water-vapor. This result is accomplished by arranging the steam-tube between the hydrogen-tube and the oxygen-tube.
The drawings represent three examples of an apparatus for carrying the invention into efiect.
Figure l is a longitudinal section of one form of the apparatus on lineA B, Fig. 2 Fig. 2, a sideelevation thereof; Fig. 3, a front elevation; Fig. 4, a longitudinal section of a modification on line C D,'Fig. 5; Fig. 5, a lon-' gitudinal section on line E F, Fig. 4; Fig. 6, a cross-section on line G H, Fig. 4:; Fig.7, a plan of a further modification; Fig, 8, a longitudinal section on line IK, Fig, 7 and Fig. 9 a cross-section on line L M, Fig. 7.
In Figs. 1 to 3 the apparatus comprises three tubes (0, b, and c, which are arranged close to one another and of which the outer tubes at and o serve for supplying, respectively, hydrogen and oxygen or air, while the central tube 12 serves for supplying the watervapor; The ends of the three tubes a, b, and c are united in a casing d, composed of two The Serial No. 67,417. (No model.)
parts which may be of equal size and are connected by screws 6 or in similar manner. At the ends the tubes to and c are provided with burners .of steatite or other refractory material, which are slotted similar to gas-burners, so that the hydrogen and oxygen are spread fan-like. The steam-supply pipe b is also provided with a similarly-shaped nozzle.
In Figs. 4. to 6 each tube a, b, and c is inserted into achamberf and isprovided with a suitable number of branches g, h, and 11,
which are led outward through upwardly-ex- In Figs. 7 to 9 the pipes a, b, and c are not led through the chambers f, as in Figs. 4 to 6; but the chambers are themselves used for conducting the gases which issue from the nozzle-like tapered openings Z. into the firechamber. The openings lconverge upwardly to form slits, so that the gases issuing there- "from arespread out fan-shaped.
In operating a boiler, furnace, stove, &c., according to my invention I proceed as follows: The tube a is first opened and the hydrogen gas is ignited in the known manner. The tube 1) is then opened, so that water-vapor is supplied to the hydrogen. Finally, the tube 0 is opened to carry oxygen to the combustion chamber. Thus the hydrogen and oxygen gases are diluted by the watervapor before being allowed to combine. The
supply-of the gases as well as of the watervapor is regulated by suitable cocks or valves arranged within the tubes (1, b, and c. If atmospheric air is admitted, only a very small quantity of oxygen is to be introduced, which may sometimes be omitted altogether. In order to avoid errors in manipulating the cooks, their handles may be so connected that the oxygen-cock cannot be opened previous to the opening of the hydrogen-cock. It will be seen that the water-vapor flows for the entire length of the fire-chamber centrally between the hydrogen and the oxygen, which likewise fiow over the entire length of 'the fire-chamber. In this way a direct contact vapor, and then causing the diluted gases to combine, substantially as specified.
2. A method of firing which consists in injecting into a fire-chamber hydrogen, oxygen, and Water-vapor intermediate the hydrogen and oxygen, substantially as specified.
