DUST- CHAMBER FOR METALLURGICAL FURNACES.
SPECIFICATION forming part of Letters PatentNo. 515,071, dated February 20, 1894.
Application filed February 28, 1893- Serial No. 464,060. (No model.)
To all whom it may concern.-
Be it known that we, ARTHUR GHANUTE and MALVERN W. ILES, citizens of the United States, both residing at Denver, in the county of Arapahoe, in the State of Colorado, have invented a certainnew and useful Improvement in Dust Chambers for Metallurgical Furnaces, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.
Our invention relates to what is known as the dust chamber of a furnace; that is to say, the chamber into which the smoke of metallurgical furnaces passes from the furnace on the Way to they stack or to a screen system where the metallic fume is to be screened from the gases.
The object of our invention is to cool the gases, &c., somewhat in the dust chamber, thus carrying so tospeak the cooling flue system which usually connects the said cylinder with the screens into the dust chamber, and also to utilize the heat of said chamber for heating the blast forced into the furnaces.
Our invention will be best understood as described in connection with the drawings in which it is illustrated and in which Figure 1 is an elevation of a system embodying our invention; Fig. 2, a cross section through the dust chamber on line 0c0c of Fig. 1, and Fig. 8 a View similar to that shown in Fig. 2 illustrating a modification.
A indicates a blast furnace having a blast pipe B connecting with tuyeres C, O, and receiving air from a blower G through pipe I.
E, is the dust chamber connecting with the furnace by a passage D and which according to our invention we divide into two parallel chambers E and E by a partition F preferably of sheet iron, using one passage, E for instance, as the dust chamber and the other E as an air flue. Preferably we arrange the partition F on an incline as shown, both because we thereby increase its surface and also because it forms a hopper bottom to the dust chamber directing the deposited dust to doors 6 through which it can be removed from time to time. It will be understood however that while we prefer to use the chamber E for dust, either chamber can be so used.
Preferably we maintain a forced draft through the air chamber by connecting it, as
by a conduit H with a blower G which is advantageously the blower forcing air into the furnace as shown, and by this connection we heat the blast going to the furnace.
Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. In combination with a furnace a cham- ARTHUR OI-IANUTE. MALVERN W. ILES.
