Description

1C. T. BRIAR STEAM GrsrmRM'oR Filed Oct. 25, 1924 Aug. 17 1926.
2 Sheets-sheet, 2
` ATTORNEYS fuel is supplied through a passage 23 controlled by an automa-tic float or other form of valve 24 so as to maintain the proper liquid fuel level around the outside of the sleeve 21. Inside of the burner casing 3 la vertically disposed tube 25 is provided and is spaced from the walls of the casing section 3 by lugs or arms 26.
A suitable defiector 27 is provided in thc sleeve 21, and centrally located and supported in any approved manner for a purpose which will hereinafter appear.
28 represents an air inlet which is formed in theA top and centrally of the casing section 3, and it is to be understood that a forced draft of air will enter at this opening 28 and may be controlled in any desired manner and connected `with any suitable source of supply.
An gniting means, as, for example, a spark plug 29, is secured in the casing sect1on`3 and communicates with the liquid fucl level compartment so that when a spark is formed it will ignite the fuel.
It will be noted 'that the fuelv space in the burner chamber is annular and is in line with the space between the tube 25 and the inner wall of the burner casing so that when the fuel is ignited the flame will be directed upwardly outside of the tube 25 andas it comes in contact with the downward draft of air it will be commingled with the air forced downwardly through the tube` 8, through the sleeve 21 and be deflected by the deflector 27 so so as to direct the heat against the walls of flue 5 and be discharged downward against the generator coils 13 and the superheating coil 16. The flow of heat and gases will then be directed upwardly throufrh the fire tubes 6 into the chamber 9 and thence to the outlet flue 10.
`to the temperature It will thus be noted that the highest temperature is in the combustion chamber 7 v`so that the coils will be rapidly heated and, due tothe circulation above described, steam will be rapidly generated, and as it is generated it will pass through the bend 18, tube 17 and superheating coil 16 to be superheated necessary, when it will then pass off through the pipe 19 and outlet 20 foruse.
Various slight changes and alterations might be made in the general form of the part-s describedl without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.
I claim: f
1. A steam generator, comprising a casing, an annular mud drum in the bottom of the casing, legs'projecting upwardly from the drum, a boiler communicating with the Supper ends of the legs, ai large centralflue in the boiler, small fire tubes outside of the flue, said casing having a combustion chamber in its lower portion and an outlet chamber above the boiler with which the smaller fire tubes of the boiler communicate, a sleeve fixed in the flue and projecting up into the upper portion of the casing which const' tutes a burner, means for directing fuel around the outside of the upper end of the sleeve, a burner tube fixed in the upper portion of the casing and spaced therefrom and around the outside of which flame from the fuel is directed, and coils in-the combustion A chamber communicating with the boiler, and! said casing having an air inlet opening at its top down' which air is directed through the last-mentloned tube, sleeve, and first-ment-ioned fiue into the combustion chamber.
*s so,
k2. A steam generator, comprising a casing, an annular mud drum in the bottom of the casing, legs projecting upwardly from the drum, a boiler communicating with the upper ends' of the legs, a large central flue in the boiler, fiue, said casing having a combustion chamber in its lower portion and an outlet chamber above the boiler with which the smaller fire tubes of the boiler communicate, a sleeve small fire tubes outside of the fixed 4in the flue and projecting up into the upper portion of the casing which constitutes a burner, means for directing fuel around the butside of the upper end of the sleeve, a burner tube fixed in the upper por-l tion of the casing and spaced therefrom and around the outside of which flame from' the fuel is directed, coils in the combustion'.
.chamber communicating with the boiler and said casing having an air inlet opening at its top down whichthe air is directed through the last-ment1oned tube, sleeve, and tirstrnentioned flue into the combustion chamber, and a superheating coil in the combustion chamber, one end of said coil communicating with the steam space of the boiler andthe other constituting an outlet.l 3. A steam 'generator,4 comprising a boiler, having a. combustion chamber below the same, and an outlet chamber above the same, fire tubes communicating with the combustion chamber and the outlet chamber,
a relatively large flue in the boiler,'means for directing heat through the flue into the combustion chamber and from the latterV through the first-mentioned fire tubes, amud drum around the combustion chamber, legs connecting the drum with the lower` portion of the boiler, a vertical series of horizontally positioned chamber,
nected to a leg and the other to the bottom of the boiler, a superheatingcoil in the bottom of the combustion chamber connected spiral coils in the combustion one end of each'eoil being conto the steam space of the boiler,`lan d burner at the top of the casing.
