Abstract
Abstract The incineration plant is provided with at least one static mixer which is disposed in the combustion gas duct leading from the furnace to a gas purifier. The static mixer is constructed in various forms, each of which includes a plurality of guide elements for dividing the gas flow into a plurality of sub-flows and for passing the sub-flows through the mixer in a criss-crossing relation. The static mixer effects a homogeneous temperature distribution in the gas as well as a homogeneous concentration distribution of any dust in the gas prior to passage of the gas to the gas purifier.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
An incineration plant comprising a furnace for burning a fuel while generating a flow of dust-containing combustion gases; a combustion gas duct communicating with said furnace to exhaust the dust-containing combustion gases from said furnace; at least one static mixer disposed in said duct to mix a flow of combustion gas passing therethrough to effect a homogeneous temperature distribution in the gas and a homogeneous concentration distribution of the dust in the gas, said static mixer including a plurality of guide means for dividing the gas flow into a plurality of sub-flows and for passing the sub-flows through said mixer in criss-crossing relation to each other; and a gas purifier communicating with said duct down-stream of said static mixer for removing the dust from the flow of combustion gas.
Claim 2
Dependent Claim
129 words
An incineration plant comprising a furnace for burning a fuel while generating a flow of dust-containing combustion gases; a combustion gas duct communicating with said furnace to exhaust the dust-containing combustion gases from said furnace; at least one static mixer disposed in said duct to mix a flow of combustion gas passing therethrough to effect a homogeneous temperature distribution in the gas and a homogeneous concentration distribution of the dust in the gas, said static mixer including a plurality of guide means for dividing the gas flow into a plurality of sub-flows and for passing the sub-flows through said mixer in criss-crossing relation to each other; and a gas purifier communicating with said duct down-stream of said static mixer for removing the dust from the flow of combustion gas.
Claim 3
Dependent Claim
34 words
An incineration plant as set forth in claim 1 which further comprises an air supply inlet in said duct upstream of said static mixer for introducing cold air into the flow of combustion gas.
Claim 4
Dependent Claim
47 words
An incineration plant as set forth in claim 1 wherein said guide elements include a plurality of corrugated lamellae disposed in parallel contacting relation with each lamellae having corrugations disposed in angular relation to said duct and in criss-crossing relation to the corrugations on an adjacent lamellae.
Claim 5
Dependent Claim
68 words
An incineration plant as set forth in claim 1 wherein said guide elements include a plurality of flat surface plates disposed in parallel spaced apart relation coaxial of said duct and a plurality of parallel spaced apart flat elements on opposite sides of each plate, said flat elements being disposed in angular relation to said duct and in criss-crossing contacting relation to flat elements on an adjacent plate.
Claim 6
Dependent Claim
67 words
An incineration plant as set forth in claim 1 wherein said guide elements include a plurality of parallel contiguous layers of tubes, each layer having said tubes thereof disposed in angular relation to said duct in criss-crossing contacting relation to said tubes of an adjacent layer, each said tube having at least one aperture in a side wall to permit communication between the interiors of adjacent tubes.
Claim 7
Dependent Claim
39 words
An incineration plant as set forth in claim 1 wherein said guide elements include a plurality of layers of strip elements with strip elements of alternating layers disposed in edgewise relation to each other and in contacting criss-crossing relation.
Claim 8
Dependent Claim
41 words
An incineration plant as set forth in claim 6 wherein said duct has a circular cross-section and each layer has elliptical configuration to fit within said duct and wherein each layer is inclined relative to each other and to said duct.
Claim 9
Dependent Claim
115 words
In combination with an incineration plant having a combustion gas duct for exhausting a flow of hot dust-containing combustion gas and a gas purifier in communication with said duct for removing dust from the flow of combustion gas; at least one static mixer disposed in said duct to mix the flow of gas passing therethrough to effect a homogeneous temperature distribution in the gas and a homogeneous concentration distribution of the dust in the gas prior to passage into said gas purifier, said static mixer including a plurality of guide means for dividing the gas flow into a plurality of sub-flows and for passing the sub-flows through said mixer in criss-crossing relation to each other.
Claim 10
