PATENT OFFIC FRANCIS RANDOLPH MACDONALD,
OF LONDON, ENG-LAND.
OIL BURNER.
Application filed September 8, 1921.
To all whom itmay concern:
Be it known that I, F RANOIS RANDOLPH MACDONALD, residing at London, England, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in or Relating to Oil Burners, of which the following is a specification.
This invention relates to liquid fuel burners of the type using fuel atomized by a jet of steam or air, and particularly to self starting liquid fuel burners of the type comprising a coil or the like adapted to be heated by the flame of the burner, a pump adapted to compress air above the water of a reservoir and means whereby the said compressed air can be used as an atomizing fluid to start the burner, said air passing through the coil and being heated by the flame after starting, the air remaining in the receiver subsequently used for forcing the water t rough the coil when said coil is sufficiently hot, thereby generating steam for the further continuous operation of the burner.
According, to this invention, the pipe, coil or the like, through which air or water is forced under pressurefor the atomization of the. fuel, is provided with means for adjusting its position and with means for removing it entirely if required after the and another supply of atomizing fluid is available.
The said pipe, coil or the like, is rapidly brought, by the heat of the burner when operated initially by air from a hand pump, to a temperature sufficiently high to immediately vapourize any small quantity of water injected in said pipe, coil or the like and to act like a flash boiler. The air supplied to the reservoir is made to pass through the said pipe or coil or the like so as to be heated on its way to the burner after the latter has been started.
A separator of suitable shape is or may be connected to each end of the pipe or coil which is exposed to the burner flame. The separator at the end through which the water enters is for the purpose of pre-heating the water to such a temperature that the bulk of any lime-salts in solutlon are deposited. The separator at the steam issuing end is for the purpose of separating from the steam any lime remaining-in it which is carried through by the steam and appears m the form of powder. The casting consti- Serial No. 499,199.
tuting these separators and the casting forming the frame or body of the burner may be combined so as to form one single casting, whlch will be bolted to the front of the furnace.
Referring to the drawings filed herewith Fig. l is a section through one of the lime separators at one end of the pipe or coil, showing diagrammatically an arrangement of burner with a coil adapted to be adjusted in position, but not removable, located above the burner, and so connected that the air passes through the coil on its way to the burner and is heated thereby, there being a lime separator at each end of the coil;
Fig. 2 is a section through the lime separators at the places where the coil passes through them, of the same arrangement as shown in Fig. 1.
Fig. 3 is a section through one of the lime separators, similar to that shown in Fig. 1, showing diagrammatically an arrangement of burner with a pipe adapted to be adjustable in position and removable when desired.
In the particular arrangement of burners illustrated by these figures, a is a hand pump, adapted to force air above water contained in a reservoir 6, c, and (Z are two branch pipes communicating with the top and bottom of the said reservoir, respectively and with a pipe 9 and provided with cocks e and f, the manipulation of which allows either compressed air or water forced up by said compressed air to be admitted into the pipe 9. it is the coil through which first air, then water, is admitted on its way to the burner z, supplied with liquid fuel from a reservoir not shown, and provided with regulating adjustable needle valves j and I: for the fuel and the atomizing fluid. The casing supporting the burner is divided into two chambers or separators Z and m, in the first of which the water is preheated so that the bulk of the lime salts in solution is deposited, while the second collects any lime salt carried by the steam.
The air or water enters the separator Z by the neck a and issuing by the pipe 0, is led to the coil h by the flexible pipe S,; the hot air or steam leaves the coil 6 by the flexible pipe S and enters the separator m by the neck ,1; and is led to the burner 2' by the bent pipe 1'. The coil it has in this case the form of an elongated hoop, the position of which is adjustable from the front of the furnace of the burner by means liquid fuel.
owing to the flexible connections S S and to passages 25,, 6 through the separators, which allow the ends of the coil h to pass to the front of the furnace. This coil is not adapted to be removed in the particular method of 1, but by using one wide opening in the lime separator casing, the whole coil may be made removable. The pipe shown in Fig. 3 18 adapted to be removed when desired as well as to be adjusted in position by any known means such as littingwitli friction in a collar (not'shown) arranged on trunnions in the opening 6, or in any other suitable manner. I
It only requires a few minutes operation of the hand pump to bring the pipe or coil h to a dull red heat. I V
When this heat has been reached, the valve 7 is slightly opened and asmall quantity of water under the pressure of the air from the hand pump applied to the surface of the water in the reservoir 5, is carried by the air and is caused to enter into the flashv pipe or coil, a drain cock (not shown) being slightly open to allow the steam condensed in'the colder portions of the piping to cape, until the wholepiping is heated by the steam. The valve has a fine adjustment so that only'minute quantities of water enter the coil.
As soon as steam is observed to issue from the drain cock, this cock is shut and the cock 6 is turned off so that the hot air supplyis cut off, and the burner is then operated continuously by the steam generated in the flash pipe or coil, the supply of water to the coil being regulated by the valve f.
The water entering the end of the coil is at once converted or flashed into steam and superheated and passes out form the other end of the coil to give the necessary pressure of steam-gas to operate the burner in placeof the air.
A pressure gauge (not shown) is provided to indicate the pressure of the steam enterin the burner and a relief valve (not shown) is fitted for safety purposes.
Suitable regulating valves, which may be automatic, relief valves, pressure gauges, water gauges, drain taps. and other necessary accessories are provided where required.
The arrangements above described can be used in connection w th any burner of the type descr1bed adapted to burn any atomizeo It is understood that the arrangement described above, as well as the shape and position of the flash pipe .or coil, are cording to tlie ;burnerusecl and the kind of fu-rnace'towhich it is fitted.
construction as shown in F1g. so constructed as to a pump adapted I may beobtained from-the said boiler after the steam supply is available, the coil being be removable, to avoid needless wear when not in use. This is shown in Fig. 1 where b is the small boiler connected to the burner by the steam pipe 9 provided with the valve or cock to. This small boiler, towhich the heat of the burner is applied for the purpose of raising steam for starting and operating larger burners not fitted with the arrangement which is the object of the present invention, may be usedinsteadof aseparate water and air reservoir to start the burner by means of a hand pump, and subsequently may be made to supply its own burner with steam when available, the coil or tube being removed.
What I claim and desire tosecure by Letters Patent'is 1. A burner for liquid by the flame of the burner, lime separating means connected at the outlet of the pipe for separating'the line carried by the water, the waterof the reservoir and means whereby the said compressed air is caused to pass through the pipe and used first as an atomizing fluid to start the burner, and subsequently to force water from the reservoir into the pipe, thereby generating steam for the further continuous operation or" the burner.
2. A burner for liquid fuel as claimed in fuel comprising a water reservoir, a pipe adapted to be heated to compress the air above claim 1 provided with means for, altering the position of the coil. 7
