System for injecting slurry to be incinerated into an incineration furnace, corresponding operating procedure, use and furnace
First Claim
1. A system for injecting slurry or other pasty wastes to be incinerated into an incineration furnace, the furnace having an incineration hearth on which household waste is deposited in order to be incinerated, the system comprising:
- an injection device for injecting the slurry to be incinerated into the furnace, the injection device being essentially situated above the incineration hearth to feed the slurry to the hearth at least in part by gravity, the injection device including,a slurry spray device for spraying the slurry as the slurry is injected into the furnace,an injection casing forming a spray chamber having a slurry feed intake and a discharge nozzle provided to inject the slurry into the furnace,a pressurized gas injection tube provided within the spray chamber and having a first end, which is fitted with a diffuser, provided in an area of the discharge nozzle of the spray chamber, anda displacement device coupled to the pressurized gas injection tube to displace the diffuser in relation to the discharge nozzle to provide adjustment of the slurry spray.

Abstract
System for injecting slurry to be incinerated into an incineration furnace, the furnace having an incineration hearth onto which the household waste is tipped in order to be incinerated, and including a device for injecting the slurry to be incinerated into the furnace, essentially fitted above the incineration hearth in such a way as to allow the slurry to be fed to the hearth at least in part by gravity, the injection device being fitted with a spray device to spray the slurry when it is injected into the furnace, wherein the said injection device has an injection casing forming a spray chamber with a slurry feed intake, and a discharge nozzle, for injecting the slurry into the furnace, the said chamber being crossed by a pressurized air injection tube, the end of which is fitted with a diffuser in the area of the nozzle of the said chamber, the said injection casing being mounted onto a pivot and working together with a telescopic rod for adjusting the angle of the injection casing by rotation around the said pivot.

14. A process of incinerating slurry type wastes in an incineration furnace having an incineration hearth on which household waste is deposited and having an injection device situated so as to feed slurry to the incineration hearth, the process comprising the steps of:
-
feeding slurry to a spray chamber of the injection device; feeding the slurry through the spray chamber past a gas injection tube having a diffuser formed on an end thereof; feeding the slurry to a discharge nozzle of the injection device to discharge a slurry spray; and adjusting the slurry spray exiting the discharge tube by moving the diffuser of the gas injection tube relative to the discharge nozzle. - View Dependent Claims (15, 16, 17)
