METHOD OF BURNING GAS.

Specification of Letters Batent.

Patented Jan. 11, 1916.

. Application filed December 12. 1914. Serial No. 876.998.

To all Ir/1.0m. "it m (1 on ern 1 Be it known that l. \l'inL-Lvn' K. 'l\vo.\Ii-;Y, a citizen of the l nited States, residing at Chicago. in the countyof Cook and Stateof lllinois,-'liavo invented certain new and useful Improvements in '.\lethod s oi Buruing ('ias, of which the following is a specification.

This invention pertains to an improved method or process of burning gas in such a manner as to secure complete combustion, the products resulting from such combustion being practically odorless and possessing advantageous sterilizing characteristics.

In carrying out the invention in the preferred manner, tho gas, initially mixed with air, is burned in a. primary. burner, from which the unburned portions and the products of thecon'rhl'istion are broken up or subdivided. mixed with more air, heated and confined, to control or steady an otherwise possibly variable. pressure. lhennixtnre is burned a second time. and the resulting products are subjected to further mixing and heating, and thento a mechanical subdivision, being at the same time additionally heated. The gases may or may not be allowed to burn again at this tin'ie, possibly spasuiodically or intermittently, before they are again assembled, mixed, heated, and finally burned. That is to say, the mixture of gas and air is burned successively three, and. possibly four, times, with such intern'iediate. treatment as to heating, mixing, subdividing. &e., between the combustions as will result in the eventually complete gaseous combustion.

A burner working on the principle of this invention may be used for the various pi. rposcs for which heating gas hurners are ordinarily employ ed. In order, however, that a. full understanding of the invention may be had, I have, in the accompanying drawing, illustrated a burner for roomheating, capable of carrying on the gas combustion in accordance with the principles of this improved method or process.

In this drawing, Figure 1 is a central vertical section of the burner structure: and Fig. 2 is a longitudinal, vertical section on line. 2-2 of Fig. 1, the parts being viewed in the. direction indicated by the-arrows.

Referring to the. drawing, it will be. observed that the initiator primary burner 9, voricim on the Bunsenbnrner principle, is supplied with mixed gas and airthrougli the pipes 10 and 11 in the usual manner, the gas. in passing from the one to the other, entraining a proper amount of air. The multiple bnrncr is supported on legs or feet 1;. which carr v a pair of Lent bars or standards i l and ll. on which is mounted a cenlrallv-aperturcd metallic-plate 15, through the hole of which the vertical inner end of the bent pip it extends, being provided at its top with the burner 9.

hollow. rectangular. preterablyeastmetal.control-box ll' rests on the plate 15, and centrally receives the burner 9. As is illustrated. the top and bottom of the box proper are open. but when in position, as shown. the. bottom is covered by the centrall vaperiured part of plate 1:), and the top is equipped with a cover plate 17, which rests upon and is spaced away from the. upper edges of the box by means of short supporting lugs 13, lb. rising from the top edges of the box sides.

.-\u openliottom. rectangular casing 19, with a longitrulinal. horizontal corner burner-opening '30, rests on plate 15 and snugly lits over the sides of the control box 16. being materially longer'than the box, as shown in Fig. '2. Above the cover or plate 1?. casing 19, is equipped with a horixontal grid or grille 21, made of crossing longitiulinal and transverse rods or wires, as shown. This arrangement of parts pro vides a chamber!) above the grid or apertured screen. and a compartment 23 below it, arronnnodating burner-9 and its associated surrounding control-box 1G.

The entire structure is covered with an open-trout shell or housing 2t, and is supplied with an inclined wall 25, which, if desired, may be covered with asbestos or similar material, against which the final flame at the jet-opening 20 may play. This shield prevents air currents from unduly affecting the flame.

The method of burning the gas in this ap pliance. is substantially as follows: The mixture of gas and air passing in pipe 11 is burned at the first or primary burner 9 in the usual manner, atmospheric air entering the control box 16 througlrthe admission aperture in plate 1:3, supplying the fuel with the. needed oxygen of combustion, that is supplementing that already mixed with the gas. The control box 16 is preferably sufficiently small so that the flames fromthe burner 9 play or impinge directly against its inner surfaces. The box, being thus relatively small, also regulates or steadies the gas pressure and prevents fluctuations, not only in the pressure, but also of the flames outside of the box. The volume of this box such that the gas is temporarily retained therein, resulting in its subjection to a high ture burns in the chamber or compartment 23, and owing to the circulation-and swirling of the gases therein, a further intermixture of the ingredients is brought about. The grid 21 acts to retard the passage of the mixture and to retain it temporarily in the chamber 23, so that it is subjected additionally to the heat of the box 16 and to the fiamis in the chamber. This chamber 23, being somewhat larger than the box 16, permits the mixture to expand, and, of course, during such expansion it is held at a high temperature, in this way assisting the preparation of the mixture for further combustion.

The mixture, as it passes through the grid, is subdivided into a large number of jets, each ofwhich is subjected to the heat of the grid} which contacts with most of the gas .particles and causes a disassociation of some and thelighter gases may or maynot burn above'such grille or screen. If they burn, the combustion is ordinarily more or loss fluctuating and intermittent. The chamber 22, as has been indicated, permits the further intermixture of the uniting jets and prepares the gaseous mixture forthe final combustion or tmrning, which occurs at the jet-opening or slot "20, such flame rccciving additional oxy en for the carrying on of the combustion from thc.cxtcrn:.1l atmosphere.

Presenting the matter somewhat differently, the mixture of gas and air is burned successively three or four timcs, being retarded in its passage through the multiple burner so. as to be subjected to hcating between the combustions, the mixture being also treated with respect to pressure and the. inter-mixture of the ingredients so as to render'possible the successive burnings referred .to. -'..Owing to the treatment to which the steady, receiving oxygen from the outer: air for promoting combustion. The bacteria whiclrmay have been present are destroyed, and the resulting products of combustion may be employed. if desired. fortheir steri living qualities.

The general principles of this improved and novel method and process have been indicated above, but the various steps in the process may be changed more or less and still retain all of the essential and vital features of the method. Consequently, the claims appended hereto should receive a liberal interpretation, in view of the novelty and various features of-improvement present in the process.

\Vhile I have herein described the burner as being provided with a hollow rectangular cast-metal control-box, it is to be understood that the shape of such box is largely imma terial and that its form may be varied within wide limits. For example, it might be round 'or of hexagonal or other shape.
