FURNACE. Y 1V Application filed February 5, 1923.- Serial No. 617,068.

To all whom t may concern.' f

Be it known that I, VICTOR TAN1ER,.engi neer, a subject of the King of Belgium, residing at Sclaigneaux, in the Kingdomof Belgium, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.

This invention has for its Vobject to ,pro-

vide an improved furnace wherein the heating chamber 1s composed of two halves separated by a longitudinal partition, and itrelates more especially to regenerator furnaces designed for heating crucibles for effecting the reduction of ores.

Furnaces of this type are known, particularly those wherein the crucibles are ar` ranged in a certain number o-f horizontal rows situated above one another, having a combustion chamber beneath the bottom row. In that known construction, the products ofcombustion ascend from one row to another up to the highest row through half of the heating chamber on one side of the furnace, and then descend through the other half of the heating chamber.

In other known types ofl furnaces, the path of the products of combustion is the reverse, namely down on one sideof the furnace and then up on the other side of the furnace.

In a third known type of furnace, the combustion chamber is arranged between the two halves of the heating chamber. The burnt gases fill the heating chamber, descend to some extent, and pass off tothe regenerate-rs.

' That type of furnace has the great drawback that there is not a regular and uniform heating throughout the heating chamber which is an essential quality of a furnace giving a really economical output.

The reduction is not effected simultaneously. The crucibles in the bottom row (or top row) are subjected to a more intense heat than the other rows, thus entailing a rapid deterioration. v

With the ob'eot of obviating all those drawbacks and obtaining a temperature as constant as possible throughout the entire length of the heating chamber, the present invention comprises the following features f 1. Complete separation between the two halves of the heating-chamber by means of a longitudinal partition which extends up to the roof of the furnace and renders the twor halves of the heating chamber quite independent of each other, thus allowing of heating each half independently. Theduots for supplying and discharging the gases are formed in the aforesaid longitudinal parti-k tion. The flow of Jche gases in the furnace takes place in a longitudinal direction. By blocking the orices of the gas ducts sup-- plying one of the halves of the heating chamber, the said half is placed completely out of action, so that it can be repaired or altered while the other -half of the chamber is kept working; f f

2. Regulation of the supply of air and gas by subdividing the regenerators into inde-v pendent sectio-ns. By this means it ispossible to regulate the supply of air and gas in every part of the `heating chamber. Y

By increasing the supply to the parts that are insufliciently heated, 4and reducing the supply to the parts that are overheated, the heating can be so regulated as to vrobtain an vheating almost uniform temperature throughout thel f length of the heating chamber.

In the case of a certain number of rows the 'airl and gas supplyk apertures may be so arranged as to allow gas only, or air only, orn both gas and air,V together to enter the heating chamber at the level of each row of crucibles.`

In that instance, the present invention provides also another` means for enabling the temperature to: be regulated under each row, for which purpose a cross partition is ar-r ranged in the middle of the heatingy chamber. YThis cross partition is provided with apertures situated at different levels. By blocking these apertures more or less, the

gases are compelled tofollow any desired 9 path. By this means therefore the flow of the gases can be increased underneath some of the rows, and diminished underneath other rows.

The accompanyingdrawings illustrate by way of example a constructional form of the improved regenerator furnace designed for heating crucibles ina plurality of horii furnace taken along the lines c-cZ of Figure 1 and e-f of Figure 3.

Figure 3 is a vertical section of the other half of the furnace taken along the lines L-JL" of Figure 2 and of Figure 5.

Figure 4 is a horizontal' section of the furnace taken along the line -ZZ-mm-e of Figure 5.

Figure 5 is a transverse section of the furnace taken along the line -0-;o-p of Figures 2 and Il;

As shown, the improved furnace comprises aheating chamber divided by a longitudinal partition i into two entirely independenthalves 2 and 3 (Figure 5).

The ducts' d and 5 for supplying the air and gas are formed vertically in the longitudinal: partit-ion 1 throughout the length of the heatingchamber in such a manner that-an airdu'ct is situated by the side of ga'sduct.k These ducts communicate through i'lu'es 6 andi' 6 with the four regenerators 7, 8andr '77, 8 situated at the two longitudinal sides ofthe furnace. Also, two or more air ducts may be provided for one gas duct.

rllhe air and gas, coming from the gas main 13- or air main 14', passl into the regenerators,4 for instance .7 and 8, that are then working, wherein they become heated andp'a'ss along the flues and 6 into the vertical ducts' 4! and 5 formed in the wall 1.

Inthe construction illustrated in Figure 5, where the crucibles are arranged in four horizontal rows one above another, the ducts /land are providedwith apertures 15 and 16 on aV level with each row of crucibles. li-"ior-izontal ducts 17 and 18 supply air and gasi'n the proximity of each row where combustion takes place: rlhe products of combustion pass along the heating'chamber until they meet a cross partition 21 in the middle of the heating chamber. The burnt gases then pass through the apertures 22 formed in the cross partition 21 at the levels of the various rows,l and they arrive at the other end'of the heating chamber at the horizontal ducts 17 and 18 at the aperturc'sl and 1G and at the vertical ducts Il and 5 on their way to the regenerators 7 and 8 which are thereby 'heated up.

After the reversal the gases travel in the reverse direction.

Forl the purpose of enabling the heating to be regulated as desired, the air and gas regenerators are subdivided according to this inventionA into independent compart- `ments 11 for the air and 12 for'the gas.: Theair and gas enter by way of the air mains 13 and gas mains 1.a into the said compartments through apertures 19 provided ineach compartment. Each of these aperturesV 19 is adapted to be closed by a damper for the purpose of regulating the quantity of air or gas passing through. ln the illustrated example the several apertures 19 may be closed to a greater or less extent by means of a brick 19. Apertures 20 closed by plugs (capable of being withdrawn for obtaining access to the bricks 19') are provided opposite the apertures 19 in the air and gas mains.
