Abstract

Abstract A horizontal trough accommodates a body of water and has two transversely spaced lateral sides one of which is provided with an edge. A substantially vertical discharge chute has an upper endportion into which slag and other combustion residue from a furnace is permitted to enter and a lower endportion with an outlet through which the residue enters into the trough. The lower endportion is bounded by two transversely spaced walls one of which is closer to the first edge and the other of which is closer to the second edge of the trough, with the other wall being vertically movable with reference to the stationary upper portion of the chute. A pusher pushes residue out of the trough, beneath the vertically movable wall and over the free edge of the trough.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 162 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and a second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge; and mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement in response to a force exerted on said second wall portion by combustion residue being pushed towards said second side by said pusher means.
Claim 2
Dependent Claim 162 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and a second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge; and mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement in response to a force exerted on said second wall portion by combustion residue being pushed towards said second side by said pusher means.
Claim 3
Dependent Claim 162 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and a second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement; a cover wall extending along and covering said tray; pivoting means pivotally mounting said cover wall on said second wall portion for movement therewith; and pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge.
Claim 4
Dependent Claim 162 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and a second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement; a cover wall extending along and covering said tray; pivoting means pivotally mounting said cover wall on said second wall portion for movement therewith; and pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge.
Claim 5
Dependent Claim 29 words
A combination as defined in claim 2, said pivoting means comprising pivotable arms supporting said cover wall and connected with said second wall portion for movement with the latter.
Claim 6
Dependent Claim 26 words
A combination as defined in claim 1, said second wall portion having a lower edge region provided with a guide surface facing downwardly into said trays.
Claim 7
Dependent Claim 36 words
A combination as defined in claim 1, said second wall portion being movable to and from a normal lower end position; and further comprising biasing means biasing said second wall portion to said lower end position.
Claim 8
Dependent Claim 13 words
A combination as defined in claim 5, said biasing means comprising spring means.
Claim 9
Dependent Claim 13 words
A combination as defined in claim 5, said biasing means comprising hydraulic means.
Claim 10
Dependent Claim 38 words
A combination as defined in claim 5, said mounting means including a pivot arm connecting said second wall portion with said upper end portion; and wherein said biasing means is connected with and acts upon said pivot arm.
Claim 11
Dependent Claim 190 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement; dispenser means carried by by said second wall portion and having outlet nozzles directed into said tray, said dispenser means being connected with a source of water and having its receipt of water from such source controlled in dependence upon the position of said second wall portion relative to said upper end portion; and pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge.
Claim 12
Dependent Claim 190 words
In a furnace, a combination comprising a substantially horizontal tray adapted to accommodate a body of water and having a first and second lateral side with the latter having an edge; a substantially vertical chute having an upper end portion adapted to receive combustion residue from a furnace, and a lower end portion provided with an outlet bounded in part at opposite sides by a first wall portion closer to said first side and a second wall portion closer to said second side; mounting means mounting said second wall portion on said upper end portion for substantially vertical displacement; dispenser means carried by by said second wall portion and having outlet nozzles directed into said tray, said dispenser means being connected with a source of water and having its receipt of water from such source controlled in dependence upon the position of said second wall portion relative to said upper end portion; and pusher means in said tray in the region of said first side and first wall portion and being operative for pushing combustion residue entering said tray from said outlet to said second side and over said edge.
Claim 13
Dependent Claim 35 words
A combination as defined in claim 2, wherein said second wall portion and said cover wall are composed of a plurality of wall sections respectively arranged adjacent one another in longitudinal direction of said trays.
