HYDROGARB ON-B URNEB.
Specification of Letters Patent.
Patented Tan. 12, 1909.
Application filed May 1, 1908. Serial No. 430,305.
To all whom it may concern:
Be it known that 1, PETER M. KELLER, a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.
The prime object of this invention is to provide a hydro-carbon burner which is simple in construction and which will efliciently burn the hydro-carbons in combination with steam or air supplied thereto.
T 1e burner consists essentially of a means to raise the hydro-carbons to high temperature approximately around their vaporizing point, before they are atomized by the stream of steam or air. This initial heating of the hydro-carbons provides for quick combustion when they are thrown into the flame.
I accomplish the above by means of the device described herein and illustrated in the accompanying drawings, in which figure 1,is a longitudinal section of my improved burner. liig. 2,is a perspective view of the same. Fig. 3,is a horizontal section taken on line 3 of Fig. 1. l ig. 1,- is ahorizontal section taken on line i of 1.
In its approved form this burner consists essentially of a member 5 preferably formed of a solid piece or block of metal of rectangular cross-section with a sloping front face 6. Longitudinally bored thr ugh member 5 are two preferably circular passage ways 7 and 8, one vertically above the other. Upper passage way or bore 7 is connected to any convenient source of oil supply by a pipe 9 controlled by a valve 10 and lower bore 8 is similarly connected. to a source of steam or compressed air supply by a pipe 11 controlled by a valve 12. Leading between the two bores at a point close to their inlet ends is a passage way 13 controlled by a conical valve stopper 14 formed on the end of a set screw 15. By opening this passage way the steam from supply pipe 11 may be allowed to pass through the oil passage 7 and thus clean out any deposit which accumulates therein.
On front sloping surface 6 a centrally enlarged groove 16 leads from the discharge of oil passage 7 to the discharge of steam passage 8. Around the discharge of steam passage 8 a small chamber 17 is formed which catches the oil passing down groove 16 and prevents it from dripping off the burner before it is caught and atomized. by the steam emerging from passage 8.
in passing down groove 16 the oil is subjected to the heat of the flame and its temperature is raised so that its atomization is easily accomplished and its combustion talres place quickly after being thrown into the flame. The oii and steam are thrown out from chamber 17 in the form of a fine spray in a fan shape, the particular configuration of the fan being determined by the configuration of the chamber 17. The siope of face 6 and the length of the face of groove 16 will depend upon the length of time it is desired to heat the oiis before coming in contact with the steam issuing from passage he length of member 5 may also be determined in accordance with. the distance to which the burner is desired to project into the firebox, the oil being also heated during its passage through bore 7 as member is kept at a high temperature by exposure to the heat of the flame.
In using heavy oils the liquid is apt to come into the groove intermittently and the enlargement provides for its accommodation without allowing it to spread over face 6 and thus escape the steam jet.
Having descrilied my invention, what 1 claim as new and. desire to secure by Letters Patent is z 1. A hydro-carbon burner, comprising a member having an inclined face, a hydrocarbon passage discharging on the face, a steam passage discharging on the face directly beneath the hydro-carhon passage, and a groove in the face leading from one passage to the other, said groove being enlarged in its central portion.
2. A hydro carbon burner. comprising a member having an inclined. race, hydrocarbon passage discharging near the top of said face, a steam passage (.iischarging near the bottom of said face and directly beneath the hydro-carbon passage, a centrally enlarged groove in said face connecting the two passages, and a chamber in the face around. the discharge of the steam passage.
in witness that )1 claim the foregoing I have hereunto subscribed. my name this 22nd day of April, 1908.
PETER M. KELLER.
