Estimating the term…
A method of inhibiting formation of unburned substances in incinerating refuse is practiced with use of an incinerator wherein a peripheral wall defining a combustion chamber is provided with a nozzle for injecting at least one mixing fluid selected from the group consisting of air, water, water vapor, inert gas and combustion exhaust gas into the combustion chamber and producing a swirling stream of the fluid within the chamber. When the refuse is incinerated, the mixing fluid is injected into the combustion chamber from the nozzle, whereby the flame and unburned substances produced within the chamber are efficiently mixed with an excessive portion of air supplied to the chamber and remaining therein to ensure promoted complete combustion.
In a method for incinerating refuse in a refuse incinerator comprising:
A refuse incinerator comprising a primary combustion chamber and a secondary combustion chamber positioned above said primary combustion chamber and in communication therewith, said refuse incinerator having a constricted portion in said secondary combustion chamber provided near to said primary combustion chamber and having a peripheral wall of said primary combustion chamber which is provided with at least three nozzles for injecting at least one mixing fluid selected from the group consisting of air, water, water vapor, an inert gas and a combustion exhaust gas into said primary combustion chamber, said nozzle outlets being disposed tangentially to a phantom circle, thereby producing a swirling stream of said fluid within said primary combustion chamber.
