b (5Z5 151 50277, '12 may sci-we" lie it. known that I, CARL FABIAN RICH- von lZOCH, a subject of ihe King of on, residing at Stockholm, in the Kingdom of Sweden, have ini'enied a new and i hod of and Means for Healing IlilSfiS high Tcniperaiures, of which the following is a specification, referencebeing l to lh drawing accompanying and forming a part hereof.
well lznown in the art that in furfor heating gases to high tempera;
' for instance for producing reactions in gases, a higher tlierinic eficct and thus an increased. output may be obtained. by preparaiorily heating the gas or gases to he iireaied in the furnace.
The object of the invention is to make it possible to combine the aforesaid advantages .cf pr paratorily heating the gas or gases to as high temperature with that of an eii'ecsire insulation of the walls or other parts of the furnace in respect of h at and electriciiy.
The invention consists, chiefly, in supplyring heated gas or gases to the Zone or Zones of the furnace in which further heating is to be en ured and at the same time supplyaratively cool gas or gases around he said zone or zones.
arr inn; the invention into efi'ec any.
-. uitable for heating gases, or
a d to work with heated gases, may be employed. Freierahly, the furnace is prol lQ i i'a'i with one or more central openings for supplying heat-ed gas or gases and one or more openings surrounding the former for n "reducing comparatively cool gas or gases. u the drawing, l have shown by way of inple, two fiuri'iaces embodying the inowe: a:
o the zone of ihe eleo thusprotect the electrodes, the walls of the furnace and adjacent paris, reduce the losses of heae from the furnace and prevent discharge of the electric current to the Wall of the furnace or parts of the furnace situated outside the hot zone.
An increased action may he obtained by imparting a ro'rary movement to the gases supplied'fo the furnace. In Figs. 3 and Q I have shown an example of such an arrangement employed in a furnace 6 whose source of energy 7, consisting of an electric arc, a gas flame or other hot body, extends in the direci' on of the current. The cool gas or gases are supplied'through openings 8 one or more of which extend tangentially or obliquely so as to impart a rotary movement io the said or gases. The heated which n" is sup} l through the opening 9. On ac count of the rotation, the cool gas or sweep along the walls of the furnace while the gas supplied the cenl'er, due to its higher iei'nperature or its lower specific weight, remains at and about the axis of rolation.
The preparatory heating of the gas may be effected in several ways for instance by causing it to pass along a heated part of the furnace, by separate sources of heat or, pref erably, by utilizing the heat of the exhaust uses. The parts of the furnace, electrodes, 0., situated Within the Zone in which the eated is introduced may, obviously, he roiected by separate insulaiion or cooling rom being too sirongly heated. The supily openings for the gases may be placed in the bottom of the furnace or in the Walls thereof or in both, as shown in the drawing, and they may be made as separate openings or sliis arranged in. groups, or in- Hie shape of arcs, or otherwise, or as continuous sliis, preferably annular in shape.
I claim:
1. The process of heating 9, emperature, which consists in r D l inclosing said preheated gas in an i I or" comparatively cool gas, and advancing said preheated gas and its inclcsing envelop in the same direction past a further source or heat, meanwhile subjecting the said prehcaied lo said "further source of heat.
2. The process of heating gas to a high emperziiure, which CODSlS JS in preheating the gas, inalosing said preheaied gas in .a
1" or may not have a rotary motion Gopies of this patent may be obtained for -ture of the hot gas supplied through the first-mentioned opening.
5. The process of heating gas to a high temperature, which consists in preheating the gas, inclosing said preheated gas in an envelop of comparatively cool gas, and then subjecting .the inclosed preheated gas to a further source of heat.
