Abstract
Abstract A method of incinerating pretreated industrial waste, according to which the wastes conveyed to the incinerator in containers is pretreated either by deep-freezing the wastes or by volatilizing the wastes under exclusion of air, or by mixing the wastes with substances of addition or with leaning substances, e.g., mud, ash, sand, wood shavings, whereupon the thus obtained wastes, either reduced in size or in volatilized condition are fed into the fire chamber of the incinerator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A method of incinerating industrial wastes fed to the incinerator in containers of different contents and of unknown composition, which includes the steps of: pretreating the wastes to be incinerated by volatilizing under exclusion of air the wastes to be incinerated while supplying volatilizing heat thereto, feeding the thus obtained vapors and volatilized residues into the combustion chamber of the incinerator, and determining the combustion air for the combustion chamber on the basis of the quantity of wastes fed peR hour into the combustion chamber and on the heating power of said wastes and on the air excess-coefficient and feeding the thus determined quantity of air into the combustion chamber of the incinerator, the quantity of combustion air being so selected that the wastes being fed into the combustion chamber of the incinerator per time unit, especially those reacting at the fastest rate, will be burned completely.
Claim 2
Independent Claim
147 words
A method of incinerating industrial wastes fed to the incinerator in containers of different contents and of unknown composition, which includes the steps of: pretreating the wastes to be incinerated by volatilizing under exclusion of air the wastes to be incinerated while supplying volatilizing heat thereto, feeding the thus obtained vapors and volatilized residues into the combustion chamber of the incinerator, and determining the combustion air for the combustion chamber on the basis of the quantity of wastes fed peR hour into the combustion chamber and on the heating power of said wastes and on the air excess-coefficient and feeding the thus determined quantity of air into the combustion chamber of the incinerator, the quantity of combustion air being so selected that the wastes being fed into the combustion chamber of the incinerator per time unit, especially those reacting at the fastest rate, will be burned completely.
Claim 3
Independent Claim
139 words
A method of incinerating industrial wastes fed to the incinerator in containers of different contents and of unknown composition, which includes the steps of: pretreating the wastes to be incinerated by mixing the wastes to be incinerated with filling substances and feeding the thus obtained mixture into the combustion chamber of the incinerator, and determining the combustion air for the combustion chamber on the basis of the quantity of wastes fed per hour into the combustion chamber and on the heating power of said wastes and on the air excess-coefficient and feeding the thus determined quantity of air into the combustion chamber of the incinerator, the quantity of combustion air being so selected that the wastes being fed into the combustion chamber of the incinerator per time unit, especially those reacting at the fastest rate, will be burned completely.
Claim 4
Independent Claim
139 words
A method of incinerating industrial wastes fed to the incinerator in containers of different contents and of unknown composition, which includes the steps of: pretreating the wastes to be incinerated by mixing the wastes to be incinerated with filling substances and feeding the thus obtained mixture into the combustion chamber of the incinerator, and determining the combustion air for the combustion chamber on the basis of the quantity of wastes fed per hour into the combustion chamber and on the heating power of said wastes and on the air excess-coefficient and feeding the thus determined quantity of air into the combustion chamber of the incinerator, the quantity of combustion air being so selected that the wastes being fed into the combustion chamber of the incinerator per time unit, especially those reacting at the fastest rate, will be burned completely.
Claim 5
Dependent Claim
24 words
A method according to claim 2, in which said filling substances are selected from the group consisting of mud, ash, sand and wood shavings.
Claim 6
Dependent Claim
71 words
A method according to claim 1, which includes the steps of providing the wastes containing containers with discharge openings, compressing said containers to a pressure to press at least a major portion of the wastes in said container out of the latter for feeding to the combustion chamber of the incinerator, and crushing the solid residues and feeding the same intermixed with said wastes into the combustion chamber of the incinerator.
Claim 7
Dependent Claim
71 words
A method according to claim 2, which includes the steps of providing the wastes containing containers with discharge openings, compressing said containers to a pressure to press at least a major portion of the wastes in said container out of the latter for feeding to the combustion chamber of the incinerator, and crushing the solid residues and feeding the same intermixed with said wastes into the combustion chamber of the incinerator.
Claim 8
Dependent Claim
30 words
A method according to claim 4, in which the discharge of the wastes from the respective container therefor and the crushing of said container is effected in an inert atmosphere.
Claim 9
Dependent Claim
30 words
A method according to claim 5, in which the discharge of the wastes from the respective container therefor and the crushing of said container is effected in an inert atmosphere.
Claim 10
Dependent Claim
22 words
A method according to claim 1, which includes the step of mixing filling substances to the wastes prior to volatilizing said wastes.
