CHARLES E. DUNCAN, OF JOHNSTOWN, PENNSYLVANIA.
REG-ENERATING-FURNACE.
Application filed February 10, 1917.
To all whom it may concern:
Be it known that I, CHARLES E. DUNCAN,
residing at Johnstown, in the county of 'Cambria and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Regenerating-Furnaces, of which improvement the following is a specification.
The invention described herein relates to certain improvements in regenerating chambers for furnaces. It has heretofore been customary to fill the gas and air chambers with anuninterrupted mass or body of checker work which is supported by tiles forming alternately the entrance and exit fines of the chambers. The products of combustion carry with them a more or less soot, dust, etc., which are deposited in the checker work, as the products of combustion flow outwardly from the heating chamber through the checker work, thereby reducing the areas of the openings in the checker work, with a consequent loss of efiiciency. It has been the practice to remove the clogging deposits by directing air under pressure through the chambers, but these blasts of air simply shifted the clogging material from one portion of the checker work to another.
The object of the invention described herein is to provide pockets or unobstructed passages into which the dust, soot, etc. can be forced by the air blasts, and from which they can be withdrawn. The invention is hereinafter more fully described and claimed.
In the accompanying drawing forming a part of this specification, Figure 1 is a section plan view of the regenerating chambers of a furnace, having checker work embodying the improvement claimed herein and Fig. 2 is a sectional elevation of the same, the plane of section being indicated by the line 11-11, Fig. 1.
In the-practice of the invention, bricks forming the checker work are arranged in Specification of Letters Patent.
Patented Oct. 29, 1918.
Serial No. 147,949.
the usual or any suitable manner, the mass of brick work being supported as usual by the tiles 2 which are spaced apart so as to form fines for the infiowing gas and air, and the outlet lines for the products of combustion. In arrangin the bricks forming the checker work, podkets or vertical passages 3 are formed, said pockets extending vertically and horizontally through the entire mass of brick and arranged in line with the openings 4 formed in the outer walls of the chambers for the removal of dust, carbon, etc, and for replacing the checker work or portions thereof. When forcing air under pressure through the checker work, the air will take the path of least resistance, which will be toward these pockets, so that the dust and soot will be carried thereinto in lieu of being shifted merely from one portion of the checker work'to another. In case it should become necessary, the bulk heads formed in the openings 4 can be broken out and the soot and dust removed from the pockets or passages 3.
I claim herein as my invention:
1. A regenerating chamber for furnaces having the checker work built up in a plurality of sections such sections being spaced distances apart to form between adjacent sections vertical unobstructed passages extending through the checker work down to the fines underlying the checker work.
2. A regenerating chamber for furnaces having the checker work built'up in a plurality of sections such sections being spaced distances apart to form between adjacent sections vertical unobstructed passages extending through the checker work down to the fines underlying the checker work, and openmgs in the walls of the chamber in line with the passages formed between sections.
In testimony whereof, I have hereunto set my hand.
CHARLES E. DUN CAN. Witness:
KATHERINE O. STATLER.
