2 Claims. (Cl. 263-15) This invention relates to improvementsin regenerators for open hearth furnaces and the like, and more particularly to improvements in the distribution of air to be heated therethrough.
t is among the objects of the present invention to provide a system for injecting air evenly into regenerators. It is another object to prolong the life of regenerators. It is a further object to provide better combustion in open hearth furnaces and the like.
The foregoing and further objects will be apparent from the specification and drawings, wherein:
Figure 1 is a horizontal view partly in section of a regenerator embodying our invention:
Figure 2 is a vertical section on line II--II of Figure 1;
, ward side of the chambers, beingv smallest at the 2li is opened so'that compressed air from the Figure 3 is an end view, partly in section, along the lines III-.III of Figure 2; and
Figure 4 is a side view, partly in section, of a ue showing the ports therein.
Referring more particularly to the drawings, the letter A designates a regenerator for an open hearth furnace or the like composed of two chambers 2 and 4 having checkerbrick B therein supported by arches 8 on rider walls III.
Hot gases from the combustion chamber of a furnace, such as an open hearth (not shown), are admitted to the chambers 2 and 4 through ports B and B' and are withdrawn therefrom through openings C and C', into flue D and stack E. Ports B and B', also function to withdraw heated air from the chambers 2 and 4 to support combustion in the furnace chamber (not shown).
In accordance with the teachings of the present invention, air to be heated in the checker chambers 2 and 4, instead of being admitted thereto through openings C and C', is evenly distributed therethrough in the following manner. Flues I2 are provided in the rider walls IIJ from which ports I4 open into the respective chambers 2 and II at spaced points throughout the width thereof. The ues I2 are connected to a manifold I 6 by risers I5 and in turn the manifold I6 is connected to a compressor and pumping station I8.
In order to provide an even distribution of the air throughout the chambers 2 and 4, the ports I4 are progressively enlarged toward the rearthe station I8 will be passed through the manifold I6, risers I5, ues I2 and ports I4, and thereby be evenly distributed throughout the chambers. The heated air iiows therefrom to the combustion chamber (not shown) through ports B and B'. It is understood that while air is being heated by being passedrthrough chambers 2 and 4, similar chambers (not shown) are being heated by passing exhaust gases therethrough. During this time, the damper 22 is closed to shut off the pumping station from the exhaust gases.
While we have shown and described one speciiic embodiment of our invention, it will be understood that this embodiment is merely for the purpose of illustration and description and that various other forms may be devised within the scope of our invention, as defined in the appended claims.
We claim: 1. A regenerator comprising a, chamber, checkerwork contained in said chamber and rider walls extending across said chamber for supporting said checkerwork, means for evenlydistrbuting air to be heated through said checkerwork, said means comprising ues in said rider walls and ports opening therefrom at spaced points across the width of said chamber, and means for supplying air under pressure to said fiues, said means comprising a manifold connected to a source of air under pressure and a plurality of risers having asma-ller diameter than said manifold connecting said iiues to said manifold.
2. A regenerator comprising a chamber, checkerwork contained in said chamber and rider walls extending across said chamber for supporting said checkerwork, means for evenly REFERENCES CITED The following references are of record in the, ille of this patent:
