Abstract
Abstract An incinerator plant for burning pre-treated industrial wastes which in barrels or the like with different contents and of unknown composition are fed into the incinerator plant, the pretreatment of the pre-treated industrial wastes being effected by deep freezing the barrels with contents or the barrel contents or by evaporating the barrel contents under exclusion of air while supplying evaporating heat directly or indirectly or by mixing the barrel contents with substances of addition or leaning substances. The incinerator plant includes means for sorting the barrels, emptying same, comminuting the barrel contents and the barrels, dosing means for dosing the waste material to be incinerated to a combustion chamber which latter is followed by a post combustion chamber and by a flue gas cooling device as well as by a flue gas washing device and a flue gas heating device with flue means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
An incinerator plant for burning industrial wastes delivered in containers, which includes a pre-treating section comprising: discharging means for discharging waste containing containers and their contents, comminuting means for comminuting the waste contents of said containers, deep-freezing means adapted to receive and deep freeze wastes from said discharging and comminuting means; and a burning section which includes: a combustion device for receiving and burning the comminuted wastes, a post-burning device communicating with said combustion device for receiving therefrom wastes and further burning incompletely burned wastes, a flue gas cooling device following said post-burning device for receiving and cooling flue gas received from said post-burning device, a flue gas washing device following said flue gas cooling device for receiving flue gas from said flue gas cooling device and washing the thus obtained flue gas, and heating means with flue means for heating up the flue gas received from said flue gas washing device and releasing the washed flue gas through said flue means into the atmosphere.
Claim 2
Dependent Claim
165 words
An incinerator plant for burning industrial wastes delivered in containers, which includes a pre-treating section comprising: discharging means for discharging waste containing containers and their contents, comminuting means for comminuting the waste contents of said containers, deep-freezing means adapted to receive and deep freeze wastes from said discharging and comminuting means; and a burning section which includes: a combustion device for receiving and burning the comminuted wastes, a post-burning device communicating with said combustion device for receiving therefrom wastes and further burning incompletely burned wastes, a flue gas cooling device following said post-burning device for receiving and cooling flue gas received from said post-burning device, a flue gas washing device following said flue gas cooling device for receiving flue gas from said flue gas cooling device and washing the thus obtained flue gas, and heating means with flue means for heating up the flue gas received from said flue gas washing device and releasing the washed flue gas through said flue means into the atmosphere.
Claim 3
Dependent Claim
54 words
An incinerator according to claim 1, which includes: crushing means interposed between said deep-freezing means and said combustion device for crushing said containers, and mixing means interposed between said crushing means and said combustion device for intermixing the wastes deep frozen in said deep-freezing means and the container material crushed in said crushing means.
Claim 4
Dependent Claim
39 words
An incinerator according to claim 1, which includes dust separating means interposed between said flue gas cooling device and said flue gas washing device for withdrawing dust from the flue gas prior to entering said flue gas washing device.
Claim 5
Dependent Claim
17 words
An incinerator according to claim 3, in which said dust separating means includes at least one electro-filter.
