UNITED %ATE% PATENT UFFTQEQ JAMES HOWDEN HUME, OF GLASGOW, SCOTLAND, ASSIG-NOR TO JAMES HOWDEN & COMPANY, LIMITED, OF GLASGOW, SCOTLAND.
Application filed October 30, 1916.
To all whom it may concern.
Be it known that I, JAMES HOWDEN HUME, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Glasgow, Scotland, have invented a certain new and useful Improvement in Furnace-Fronts, of which the following is a specification.
This invention relates to fronts for forced draftfurnaces and suitable for use with oil burners of that type to which air is not required to be supplied from a point or points directly below the same. Fronts for furnaces operating on the well known Howden forced draft system are formed at the top and each of the sides of the firing entrance with valve-controlled air ports opening indirectly into the firing entrance.
In accordance with the invention the improved furnace front, which comprises an integral casting, is provided with such an arrangement of the valves and ports that the valves control the flow of air directly into the preliminary mixing chamber, there being no air passages or spaces between the valves and the mixing chamber.
In the accompanying drawings Figures 1 and 2 are vertical sections at right angles to one another; Fig. 3 a sectional plan; Fig. 4: an end elevation of a furnace front in accordance with the invention.
The furnace front shown constitutes a casting 1 formed at the top and each of the sides of the firing entrance with air ports 2 and 3 opening directly into the firing entrance of the furnacethe bottom of the Specification of Letters Patent.
Patented Apr. 14), 1917.
Serial No. 128,450.
firing entrance being unprovided with any air opening.
The air supply through said ports is controlled by valves; for example, each of the side ports 3 may be controlled by a simple butterfly valve 4, and the upper port controlled by a slide valve or damper 5.
6 denotes the preliminary mixing chamber where the air meets the oil fuel.
As shown, the furnace front is unprovided with partitions or the like affording walls of air passages between the valves and the mixing chamber 6.
7 denotes a support for the brickwork protecting the furnace front; 8 a door-giving access to the valve 5; 9 the door carrying the burners; and 10 a door giving access to the lower part of the furnace.
Nhat I claim is A front for a forced draft furnace consisting of a single integral casting providing the entire front and affording a single preliminary mixing chamber having a firing entrance at its front end, the top and side walls of said chamber being provided with air ports opening directly into said chamber, and adjustable valves, one at the top and one at each side of said chamber, for controlling the admission of air thereto.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JAMES HOWDEN HUME. Witnesses:
