HOT-BLAST STOVE.
SPECIFICATION forming part of Letters Patent No. 415,226, dated November 19, 1889.
Application filed July l5 l 8 89.
To all whom it may concern:
Be it known that I, VICTOR O. STROBEL, of Philadelphia, Philadelphia county, Pennsylvania, have invented certain new and useful Improvements in Ilot-Blast Stoves, of which the following is a specification.
This invention relates to improvements in the construct-ion of regenerative hot blast stoves designed for heating of air; &c.
)Iy improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure l is a vertical section of a stove exemplifying my improvements, the plane of this section being indicated by line a of Fig. 4, and the direction of view being indicated by the arrow e of Fig. l; Fig. 2, a vertical section of the same, taken in the plane indicated by line o of Fig. a, a portion of the base of the wall L being broken away to exhibit the work beyond, the direction of view in this section being indicated by arrow fof Fig. 4; Fig. 3, a plan of the stove; Fig. at, a horizontal section of the stove in the plane of line c of Fig. l, and Fig. a horizontal section of the stove in the plane of line d.
In the drawings, A indicates the usual eylindrical air-tight metallic shell of the stove; B, the lining-wall thereof; C, the brick roof of the stove within the roof of the metallic shell; I), the general interior of the stove within the wall B and extending from the floor of the stove to the ceiling thereof; E, a vert-ical wall diametrically disposed in the chamber D and extending' from the floor of the stove to near the top of the chamber and extending from side to side of the chamber; F, an annular series of regenerative fines in the wall B, these lues extending from near .the base to near the top; G, annular chamber in the base of the wall B at the foot of regenerative fines F; H, openings at the base of the stove placing the main chambei1 I) in free communication with the circumferential chamber G; J, the chimney-connection of the stove centrally mounted on the roof thereof; K, radial Vlines in the roof of the stove leading from the base of the chimneyeonnection to the top of the annular series of regenerative flues F; Il, a pair of vertical walls extending from the base of the stove to near the Serial No. 317,579- (No model.)
top thereof and from side to side of the main chamber I), these walls being arranged in the plane substantially at right angles to the plane of the wall E, these walls being preferably curved in horizontal cross-sections, so that each wall will present two convexities outward; M, a combustion-cham ber formed between the Walls L and extending from the base of the stove to near the top thereof and divided practically into two chambers by the cross-wall E; N, vertical walls in the main interior chamber outside the walls L, these walls extending from near the base of the stove to near the top thereof and being arranged across their chambers in both directions, so as to form regenerative flues extending from near the base to near the top of the stove; O, a connection or passage from the exterior of the stove into the com bustion-chamber M and serving as a means for admitting air of combustion to the combustion-ehamber from the stove while under gas; P, a similar connection similarly arranged and adapted to convey the gas to the combustion-chamber; Q, a connection at the top of the stove to serve in admitting' the cold blast to the stove, this connection communicating with the base of the chimneylconnection; R, a series of cleaningdoors arranged circumferentially around the base of the stove and serving to give access to the annnlar-chamber G; S, a connection leading from the exterior of the stove to the base of the combustion-chamber and serving asa hot-blast outlet.
The wall E may extend downwardly to near the door of the stove, or it may extend to the floor of the stove and have openings through its base in the combustionchamber and in the .regenerativechambers to each side thereof, as shown inthe drawings. This Wall is a stay-wall, and its presence at the base of the stove is not needed except as a vertical support for its upper portions.
It is to be understood, of course, that the connections J, O, P, Q, and S will be provided With the usual necessary Valves to permit the opening or cldsing of these connections.
Then the stove is to be put under gas for the purpose of heating the stove, the chimney-connection is to be opened, the cold-blast IOO inlet Q and the hot-blast outlet S closed, and the gas-inlet P and the inlet 0 for the air of combustion opened. The gas and air of combustion enter the combustion-chamber, commingle, vand go into combustion and ascend the combustion-chamber. Reaching the top of the combustion-chamber the cu rrent divides and passes down the two sets of regenerative iues N. Vhen the currents reach the base of the stove, theypass outwardly through the openings I-I to the annular-chamber G, and then rise-through the annular series of regenerative fines F. Upon reaching the top of these' flues the gas passes inwardly th rough the roof-fines K to the chimney-connection, by which they leave the stove. Then the stove is sufficiently heated, then the gas and air of` combustion are to be shut off and the chimneyvalve closed. The coldblast inlet Q and the hot-blast outlet S are now to be opened. The cold blast enters the stove through the base of the chimney-connection and passes through the stove in a direction the reverse of that indicated for the burning gases. The heated air leaves the stove at the connection S, the air in its passage through the stove absorbing the heat from the regenerative Wall- Work of the stove. When the stove requires to be reheated, then the inlet and outlet for blast are to be vClosed and the stove is again to be put under gas. The stoves are to be employed in multiple in the usual manner, so that one or more can be utilized in heating the blast while one or more are being heated.
I have illustrated separate connections for the inlet of gas and air of combustion and for the outlet of the heated blast. The communication of these connectionsv with the stove may, if desired, be through a single aperture into the combustion-chamber, asis cornmon in the construction of hot-blast stoves.
I claim as my invention- 1. In a regenerative hot-blaststove, the combination, substantially as set forth, of. a cylindrical metallic shell, a lining-Wall Within the shell, forming a circular interior chamber within the stove and containing an annular series of vertical regenerator-flues extending from an annular chamber at the base of said Wall to near the topv of the stove, a chimney-connection and cold-blast inlet at the top of the stove, roof-fines leading from the top of said regenerator-iiues to said chimney-connections and cold-blast inlet, a pair of vertical Walls extending across the main interior of the stove and from the base of the stove to near the top thereof, and serving to divide said main interior of the stove into a diametrically-disposed combustion-chamber and tWo segmental regencrater-chambers, all in communication With each other near the top of the stove, gas and air connections at the base of said combustion-chamber, and vertical regenerative iiues in said regenerator-chambers at each side of the combustionchamber, extending from near the top of the stove to near the bottom of the stove, and communicating With the base of the annular series of regenerator-i'lues in the lining-Wall of the stove.
2. In a regenerative hot-blast stove, the combination, substantially as set forth, of a cylindrical shell, a lining-Wall therefor inclosing the main interior of the stove and containing an annular series of vertical regenerative iiues F, communicating with the main interior of the stove at .their bases, a chimney-connection and cold-blast inlet at the top of the stove and communicating with the top of said regenerative iiues, a combustion-chamber extending dialnetrically across the main interior of the stove and reaching from the base of the stove to near the top thereof, regenerative Walls in the main interior ot the stove to each side of said combustion-chamber, and forming vertical iiues coinmunicating With said combustion-chamber at their tops and with the base of the first-inenktioned regenerative Iiues at their bases, and
air and gas connections at the base Vof said combustion-chamber.
