t" 1 claim. (ci. 15s-4) This invention relates to an apparatus for bustion promoting air, as shown, this construcburning corrosive liquids and fluids of the type tion having the advantage of supplying only Dreof acid sludge in a manner which will avoid con'- heated air for facilitating the combustion of the tact of the unconsumed sludge with any parts of iluids introduced.

One of the main objects of the invention is to The burner includes a nozzle I0 connected with provide a burner for supplying acurtain of steam a steam supply pipe I2 leading to a suitable onto which the corrosive fluids are discharged, source of supply controlled by the valve I5. The

Since the sludge nozzle I6 is entirely distinct from and separated from the steam nozzle l0, there is no contact of the sludge with the steam nozzle and no contact with any metal parts after the steam and sludge are brought into contact. 'Ihe burner has been found eclent in operation and substantially free from deterioration produced by'the corrosive character of the sludge.

While reference is made herein to a particular material to be consumed, it will be understood that the invention is not'so limited and that the apparatus is useful for disposing of any other similarly corrosive fluids.

Obviously many modifications and variations of the invention, as hereinbefore set forth, may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated in the appended claim. A

I claim:

In a furnace formed with a fire box for burning corrosive liquids, a steam nozzle constructed to provide a. fan-shaped jet of steam in said fire box, a liquid discharge nozzle positioned adjacent but out of contact with said rst-named nozzle for discharging corrosive liquids in a fanshaped stream upon said `iet of steam and a burner for fluid fuel positioned beneath said nozzles and adjacent the same for facilitating the combustion of said corrosive liquids.
