A fuel coil 2S is disposed concentric With the diffusion tube 6 and is in communication with a fuel supply tube 29 at one end thereof and in communication With the diffusion tube at the other end thereof indicated at 30. rEhe fuel supply tube extends through the cap 7 and is in communication with a fuel supply pipe 31 by means of a valve 32. A Water feeding pipe 33 is disposed in communication With the fuel supply tube 29 by means of avalve 34 so that a small quantity of water may be mixed With the'fuel. The mixture of the Water and the fuel serves the following purposes: Under the influence of heat such as hereinafter explained, the fuel is volatilized and the Water becomes more or less highly heated steam. Under this condition the particles ofi-l2() and fuel vapor attain enormous velocities in different directions. rlChese particles come into collision With one another With great violence and these collisions aid incracking or breaking up the fuel and also cause the vaporized Water and steam to diffuse one with the other. The Water or steam in the diffusion tube tends to slightly retard combustion so that when the fuel is ignited the force of the explosion is distributed over a longer periodof time Without appreciably diminishing the pressure Which the combustion of the fuel provides for power purposesl It will be readily understood by looking at Figure 2 that the average rate of flow of the fuel and Water in the diffusion part is much less than it is While the steam .and fuel are passing through parts 28, rEhe fuel and Water have therefore a relatively longer time to remain in the diffusion tube and mii; thoroughly therefore making a more efficient fuel mixture.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. With this type of combustion generator, various grades of fuel Vmay be used. With the inferior grades of fuel, a mixture of Water is necessary. However, with the superior grades of fuel, the mixture of Water is not needed. XWith the introduction of volatile fuel through the fuel tube 29 and out into the fuel diffusion tube 6 through the coil 28, there is obtained a combustible mixture by the time it reaches the innermost end of the diffusion tube. kAs the combustible mixture passes around the annular guide portion 17 and through the opening 18, `it mines with the .air and is ignited by the spark plug 20.

YWith the increase of temperature in the casing, heavy fuels and iva-ter are continuously introduced to the fuel tube 29 and combustion is maintained spontaneously between the head portion 8 and the combustion block 10, Where the fuel continues to come in contact With the air forced in through the air tube 14. 'lhe gaseous by-products, Which are exhausted through the irregular passageway 12, heat the coils 21 and 28. rllherefore, by introducing Water through the Water tube 22 and into the coil 21, steam is produced, due to the heat in the casing. The steam is allowed to pass through the coil 21 and into the casing, Where it acts as an auxiliary means for maintaining the heat Within the casing for heating the Water entering the coil 2l. Furthermore, by this same means the mixture of fuel is preheated Within the coil 28 beforeit is allowedwto pass into the fuel di usion tube (i. The steam and the by-products pass through the outlet 2.7 at a rate of speed determined by the pressure maintained in pipes 15, 2a', 31, and 33, and the relatively open or closed positions of

valves

16, 25, 32, and 34. The valvev 25 varies the speed at which the Water is allowed to pass through the Water tube 22 and into the coil 21.

The gases of combustion mingle with the `sain in the casing and. aid in heating the diffusion tube G, the coils 28 and their contents, and also the coils 21 and their contents. The steam', together with the combustion gases, passes fr in the casing through the out-let 2'?.
