Patented on2, 1945 UNITED. STATES PATENT OFFICE 7 Gas human 7 John J. Wolfersperger, Webster Groves, Mo. Application October- 21, 1940, Serial No. 362,007 8 Claims. (01. 158-99) This invention relates to 8& n 11 0011119118- tion. p
It is well known that gas and fectly mixed, will burn with a flame propagation velocity of'approximately a thousand feet per second; and, as this high flame propagation velocity is not attained inconventional gas fired equipment, it is evident that gas can-be burned in much less space, in much shorter distance of travel, and in much less time than is now done in conventional gas fired equipment, ifthe. gas and combustio mixed.
An object of this invention is to ,provide a dependable and practical method and means for effecting rapid and complete mixing simultaneously with the combustion of the mixture and air, when perthereby to effect complete and perfect combus tion in so small a space and in such short distance of travel that mixing, combustion and heat transfer can be performed simultaneously in a passageway of relatively very small crosssectional area, such as a heat transfer coil in a water heater or steam generator, thus eliminating the necessity of providing special space for combustion as is equipment.
Other objects and advantages of the inven-' tion will appear from the following description, reference being made to the annexed drawing, in which.-- Y V Fig. 1 is a vertical sectional view of a boiler equipped with one form of my present invention. Fig. 2 is an enlarged side elevation of the fuel inlet device attached to the sharply curved por-.
tion constituting the inlet to the tortuous tube.
Fig. 3 is an enlarged horizontal sectional view approximately on the line 3-4 of Fig. 1.
Fig. 4 is a sectional view on the line 4-4 of Fig. 1, showing particularly the sharply curved inlet portion of the tortuous-tubular-Dassageway.
The lower or outlet end of the tube 2 'isextended outwardly through ahole in the of the boiler and forms therewith aleakproof or hermetic Joint. A suction. device 4 is connected with the eflluent end of thextube 2 'by-a tubular,
the flue gases pass from said tube 2 tothe device 4 fitting 5 throughwhich for discharge through an outlet 8. A mercury switch I of conventional and known construction is attached to a rocking pivot.8 supported in an upward extension 9 of the fitting 5. A vane Ill attached to the pivot I extends partially across the inside of the fitting i. In its idle or unoperated position the vane i0 is approximately vertical and substantially closes the passage through the fitting 5. When the device [is operating, a suction is createdthereto through the fitting Iv and tube 2. This suction or flow ofair or flue gases swings the vane III toward the machine 4, thereby rocking the pivot 8 and moving the mercury switch 1 to close the circuit through the circuit wires ll. As shown inFig. l, the circuit is open; and, a y when the switch 1 is moved by flow of "air or flue gases caused by the machine ,the circuit through the wires H is closed, and the magnetic valve i2 in the fuel supply pipe [3 is opened.
This is because. the magnet I 4 for the valve I 2 is connected with the circuit II and is energized I to open said valve when the switch I is moved amount of air entering into the mixture of air 1 combustion mixture tube in cooperation with the cross-sectional area 1 of the tube. The sharply curved portion 3 or the tube does not 1 extend beyond the outer surface or the wall and'does'not obstruct ignited mixture into the tube. In this form of the invention,
I lar passage arranged to extending inwardly from said wallstoward the ate passage arranged and also to regulate the velocity of the and flue gases through the and gas,
straight extension of the the free induction or the the ignited mixture is given a high velocity into and through the tube, and a high turbulence and completion of mixture and compassing to the point of cross-sectional fuel gas conducted to the It is'now clear that the invention attains all of 7; its intended'objects and purposes eiliciently and 1 satisfactorily,- and can be varied without departure therefrom in other particulars than those specifically mentioned.
