HOT BLAST STOVE BURNER CONNECTION ARRANGEMENT Filled Nov. 2o, 1954 Fen/VK E. MS'EE, 3: M/
Patented Aug. 4, 1936 UNITED STAES PATENT OFFICE HOT-BLAST STOVE BURNER CONNECTION ARRANGEMENT 2 Claims.
This invention relates to hot-blast stoves, one of the objects being to improve on the burner connection arrangements of such stoves. Other objects may be inferred.
An example of a hot-blast stove embodying the present invention is illustrated by the accompanying drawing, Figure 1 being a cross-section and Figure 2 a longitudinal section of the same.
This stove is of the side-combustion two-pass type. It includes a vertical regenerator I, a bottom 2 supporting this regenerator, a vertical combustion chamber 3 associated with this regenerator, an inclined burner connection 4 opening into this chamber above the bottom 2 and a horizontal wall 5 arranged in the chamber 3 at the level of the bottom 2, this wall 5 having sufficient strength to provide lateral structural support for this bottom.
The combustion chamber 3 is associated with the regenerator l through the medium of a dome 6 which carries the products of combustion from the former to the latter and the blast from the latter to the former. A hot-blast connection 1 opens from this combustion chamber 3 so as to receive the hot blast which results when a cold blast is blown through a connectionV 8 beneath the regenerator I.
Since the burner connection 4 opens into the combustion chamber 3 well above the wall 5, there is a, section between the two which can function as a dust collecting pocket, and a manhole 9 is therefore provided for this section.
In the case of the conventional type of hotblast stove, the burner connection opens into the bottom of the combustion chamber at a right angle. Therefore, the flame impinges squarely against the wall of the combustion chamber and directly opposite the bottom supporting the regenerator. This causes the rapid destruction of the bricks adjacent the flame, and also results in the bottom receiving an excessive amount of heat which materially shortens its service life. In addition, this right angular entry of the fuel and air into the combustion Y chamber produces a baiiiing action which tends to retard the flow of the products of combustion up through the chamber.
These troubles are avoided by the stove which has just been disclosed. The inclination of the 5 connection 4 causes the flame to glance along the wall of the combustion chamber 3 at a point well above the bottom 2. It follows that the Vdestructive action of the name is greatly lessened and that the bottom receives relatively little iu heat from this source. Furthermore, the directive effect of the flame is such as to actually tend to force the products of combustion up through the chamber 3. The wall 5 functions to laterally brace the furnace bottom and to l5 prevent it from crushing what would be the combustion chamber if the stove were conventional.
It is to be understood that any type of suitable burner may be applied to the connection 4. 20 Also, that the position and inclination of this connection may be varied considerably, as well as the general construction of the stove, all with- Vout departing from the scope of the invention,
as defined by the following claims.
I claim:
1. A hot-blast stoce including the combination of a vertical regenerator, a bottom supporting said regenerator, a vertical combustion chamber associated with said regenerator, an 30 inclined burner connection opening into said chamber above said bottom, and a horizontal Wall arranged in said chamber at the level of said bottom.
2. A hot-blast stove including the combina- 35 tion of a vertical regenerator, a bottom supporting said regenerator, a vertical combustion chamber associated with said regenerator, an inclined burner connection opening into said chamber above said bottom, and a horizontal 40 wall arranged in said chamber at the level of said bottom, said wall having suicient strength to provide lateral structural support for said bottom.
