HAROLD E. YARROW, OF GLASGOW, SCOTLAND.
OIL-FIRED BOILER.
Specification of Letters Patent.
Patented Dec. 2'7, 1921.
Application filed July 8, 1919. Serial No. 309,507.
T 0 all whom it may concern Be it known that I, HAROLD EDGAR YAR- ROW, a subject of the King of Great Britain, residing in Glasgow, Scotland, have invented certain new and useful Improvements Relating to Oil-Fired Boilers, of which the following is a specification.
The invention consists in improved disposition of the oil spraying devices of the Yarrow type of boilers using oil fuel, in which there are two sets of operating tubes the lower ends of which are connected respec tively with two water drums placed on either side of-the furnace and the upper ends of which are connected with a common steam drum.
In boilers of this type, in which the burn ers are arranged approximately in the same vertical plane at thefront end of the boiler, it is found that the length of the boiler is limited in practice bythe fact that the tubes at the back of the boiler and consequently farthest from the burners, are not heated to the same extent as those nearer to the oil sprayers and act less efliciently as steam generators.
According to the invention this drawback is obviated by a disposition in which the burners are not all arranged in the same vertical plane, but in echelon, or other order,
in which some burners, or sets of burners, are nearer to the back end of the boiler.
In the accompanying drawing, which represents an example of a boiler according to the invention, Figure 1 represents diagrammatically a front end elevation of the boiler and Fig. 2 a plan with the upper part of the boiler removed.
.A is the furnace, B and B, the water drums, C the steam drum, and B the tubes connecting the water drums and steam drum. In the example shown there are 10 burners,
6 in the lower set and lin the upper. Burners F F are placed in the usual position at the front of the boiler, burners E E E,, E, are arranged in a vertical plane nearer to the back of the boiler and burners D D D D 4 in a plane still nearer to the back of the boiler. The burners are symmetrically disposed with relation to the central line of the boiler, those nearest to the back of the boiler being placed closest to the central line.
It is obvious that many different arrangements of the burners may be made in order to carry out the object of the invention,
which is to obtain a more equal distribution of the temperature throughout the furnace, and that the principle is applicable to any plurality of oil burners located at one end of said fire box, said burners being arranged symmetrically on each side of the central longitudinal plane of the boiler in sets at different distances from the said end with the sets most remote from said end placed closest to the central longitudinal plane of the boiler, substantially as described.
In testimony whereof I have signed my name to this specification.
HAROLD E. YARROW.
