HOT-BLAST STOVE FOR BLAST-FURNACES.
SPECIFICATION formingpart of Letters Patent No. 276,790, dated May 1, 1883. i Application filed September a. 1882. (No model.)
To all whom it may concern:
. Be it known that I, H. WILLIAM ELLIoo'r'r, of the city of Baltimore, and State of Maryland, have invented certain Improvements in Hot-Blast Stoves for Blast-Furnaces, of which the following is a specification.
This invention consists in the combination, with the ordinary hot-blast pipes in a hotblast stove or oven, of a gang of pipe situ-' ated below the said blast-pipes and in communication therewith, in which the air-blast is primarily heated,- combustion-chambers lo cated between the lower sections of the said gang-pipe, into which the hot gases from the furnace are introduced, having slots to allow of the escape of the gases to the upper part of the stove and thence tothe stack, and hollow heat-retainin g blocks placed over the said combustion-chambers and between the upper portions of the gang, which,in connection with the walls of the stove, prevent rapid fluctua tions in-temperature of the said air-pipe and distortion of the same,as will hereinafter fully appear.
1n the drawings forming a part hereof, Figures'I and II are vertical sections of a hotblast stove embodying my improvements, as seen from different points. Fig. III is a sectional plan taken on the dotted line 00a, Fig. I. Fig. 1V is also a sectional plan taken on the dotted line 3 y, Fig. Vl. Figs. V and VI are vertical sections of the lower part of the stove without the pipes.
Similar letters'ot' reference indicate similar parts in all the views.
A is the hot-blast stove or oven, having at its upper end the ordinary hot-blast pipes, B. G is a pipe in the form of a gang, connected at its upper end to the pipes B at a, and extending downwardly to a at the base of the oven, where it receives the cold blast. The
hot blast is delivered at b, which is the termination of the ordinary hot-blast pipes.
D D are the combustion-chambers, formed of fire-brick, into which the hot gases from the furnace areintroduced through the medium of the pipes E, and air to combine with the gases and complete combustion is admitted through the openings 0.
F F are slots through which the hot gases escape from the combustion-chambers to the interior of the oven and around the gang of pipe 0 before reaching the stacks D.
G G are hollow heat-retainin g blocks placed between the upper sections of the gang-pipe 0, against the outer surfaces of which thehot gases impinge in their passage to the oven. As before stated, the air enters cold at a and is delivered hot at b, it havingtraversed the whole length of the gang-pipe and through the different sections of the pipe B. It will be seen that both sides of the gang of pipe 0 are influenced by the action of heat from radiating surfaces, the wall of the oven furnishing one radiating-surface ,and the combustion-chambers and heat-retaining blocks the other. The
pipe Cis therefore uniformly heated and cooled,
hot-blast pipes thereof, continued to the base of the said oven by means of a gang of pipe, and the sections of the said gang separated by heat-retaining blocks,.and combustion-chambers having means for the entrance of hot gases from the furnace, and apertures for the exit of the said gases to the interior of the said oven, all combined substantiallly as and for the purpose specified.
