Description
April 2, 1929. T 4 1,707,537
REGENERATIVE coma ovsn Filed April 25,1925 2 Sheets-Sheet 2 All? V INVENTOR ATTOBN Y heat unit and in the best embodiment of the invention the direction of flow is so arranged that the flow takes place in opposite directions in the upper cross-over conduits of two neighboring heating units. By this means one obtains the great advantage that the direction of flow is the same in six adjacent regenerators. In other words, an opposite direction of flow between adjacent air and waste-heat regenerators occurs only at each fifth heating wall. I
In Figure 1, the oven is shown as heated with weak gas and strong gas. If it is desired to heat with strong gas alone. either all of the regenerators may be used for preheating air or some of the regenerators may be omitted, each of the remaining regenerators supplying preheated air to the fines of two adjacent heating walls.
Turning now to Figure 2, the direction of flow of air, burning gases and waste heat, is indicated by arrows. Oven chambers 15, are provided with heating walls 16. In each heating wall one or more systems of heating fines are provided, the burning gases flowing in' the same direction in the fines of any one heating'system. The fine systems ot the heating walls are numbered respectively, 17, '18, 19. 20, 21, 22, 23. 24. Each tine system comprises a plurality of fines extending side by side along the heating wall and the fines of the respective systems communicate at the tops or ends by means of horizontal channels 25, 2G, 27, 28, 29, 30, 31, 32. Separate cross-over conduits 33, 34, 35, 36, communicate with alternate channels and thus separately connect alternate systems of tines, thatis to say, the like fine systems of alternate heating walls are so connected. Conduit 33, connects tlue system 17, with fine system 19. conduit 34, connects flue system 18, with fiue'system 20, conduit 35, connects flue system 21, with line system 23, and conduit 36 connects flue system 22, with fine system 24.
In Figure 2, strong gas is supplied to each flue of a fine system by means of pipes 37, 38, 39, 40, 41, 42, 13, 44, there being a series of pipes for a flue system, a separate pipe for each fine-of the system. These pipes run from the underburner passageways 4:5, undcrneath the oven, the oven being supported above the ground upon posts 46. Preheated air is supplied to the flue systems by regenerators 47,;which extend below the oven chamber soles in the direction of. the oven chambers, and communicate with the flue systems by' passageways 48, there being one air passageway for each flue of a system.
It will be observed that in the form of the invention illustrated in Figure 2, in each four regenerators arranged side by side in a group, the direction of flow of waste heat or of preheated air is in the same direction, by means of which the considerable advantage is realized of reduction of leakage between regenerators, such as would occur if the direction of flow in adjacent regenerators were in opposite directions.
In the form of the invention illustrated in Figure 3, the coking chambers 49, the heating flue systems 50, 51, 52, 53, 54, 55, 56, 57, ot the heating walls 58. and the crossover conduits 59, 60, 61., 62, are constructed and arranged as in Figure '1, but the oven may also be heated by weak gas. This preheated weak gas is supplied by rcgenerators 63, weak gas being supplied to the regenerators by pipes 64. Prchcatcd air is then supplied by regenerators 65. Strong gas may also be used instead of weak gas by means of pipes 100, there being one strong gas pipe for each heating flue of a flue system. When strong gas is used preheated air may be supplied by regenerators (i3 and regenerattn's 65. Air is supplied to regenerators (i5, and 63, thru conduits 66. running underneath the regenerators to the fronts of the oven. The respective regenerators are connected to each of the heating flucs by mssagtwvays G7, (38. In the form of the invention illustrated in Figure 3, the flow of waste heat is in the same direction in eight of the neighboring regenerators and the flow of weak gas and air is likt-Wlhfl in a. common direction in another eight neighboring regenerators. Iicakage between regenerators of a group in which the direction of flow is the same, is accordingly avoided.
It will be understood that the drawings show a one period operation of the oven and that upon reversal of the oven, the flow of weak gas, and air and-the waste heat in Figure 3, is reversed. The flow will then take place indirections indicated by reversing the arrows in-this figure. The ovens of" Figures 1- and 2 may, likewise, be reversed.
Having thus described the. invention and its operation, it will be understood "that changes may be made in construction and arrangement ot' the tines without departing from the principle of the invention.
