Seal For Coke Oven Doors

View page
US Patent:
41152034, Sep 19, 1978
Filed:
Jan 6, 1977
Appl. No.:
5/757378
Inventors:
Roy Naevestad - Fanwood NJ
Assignee:
Wilputte Corporation - New Providence NJ
International Classification:
C10B 2506
C10B 2518
US Classification:
202248
Abstract:
A knife edge type of sealing means for coke oven doors having edgewise flexibility permitting the knife edge strip to adjust inwardly and outwardly with respect to the plane of the seating surface of the door jamb as the door jamb warps under service conditions due to exposure to oven heat. A number of different forms are disclosed, in several of which the knife edge strip is made up of end-butting or overlapping sections jointed for relative expansive and contractive movement, the strip being tightly held in a transversely slotted retainer support of U-shape in cross-section, which is in turn sealingly secured to a flexible diaphragm member, of either of two forms, attached to the coke oven door. Another form of knife edge sealing strip is partially slotted from the inner edge outwardly while the U-shaped retainer member is expansively jointed. Another form of knife edge has a T-shaped cross-section with the web of the T partially slotted toward the base and joined across the slots by splicing plates expansively attached to the web.

Chuck Door For Coke Oven Pusher Side Door And Heat Radiation Shield

View page
US Patent:
43728200, Feb 8, 1983
Filed:
Feb 17, 1981
Appl. No.:
6/234965
Inventors:
Roy Naevestad - Fanwood NJ
Assignee:
Wilputte Corporation - Murray Hill NJ
International Classification:
C10B 2506
US Classification:
202248
Abstract:
The invention is a new design of chuck door which has a knife-edge sealing strip that fits tightly in a slot of the door and is adjustable longitudinally by jacking screws. The strip is locked in position also by screws. The inside of the chuck door is provided with a cavity within which heat insulation refractory material is retained. A pivoted heat shield hangs from extended side heat shields in the coke oven and pivots up to allow entry of the leveler bar through the opening closed by the chuck door. The design is readily adaptable to new and to existing oven doors.

Traveling Hood For Coke Oven Emission Control

View page
US Patent:
41337212, Jan 9, 1979
Filed:
Jul 25, 1977
Appl. No.:
5/818935
Inventors:
Roy Naevestad - Fanwood NJ
Assignee:
Wilputte Corporation - New Providence NJ
International Classification:
C10B 2700
C10B 2706
C10B 4500
US Classification:
202263
Abstract:
Coke oven emission control system comprising a traveling hood for collecting the emissions arising from the quench car into which hot coke is pushed from the coke ovens. The hood has a U-shaped snorkel at the top of the hood extending longitudinally of the hood, which connects to an exhaust duct via a water trough. Within the hood are a number of nozzles which are adjusted to provide a fogging mist of atomized water particles at the time a coke oven is "pushed" which cools the emissions which rise from the quench car and thereby reduces their volume as they flow into the exhaust duct. In a modification, a venturi type scrubber in the snorkel tube serves to separate the particulates, and cool the gases as they flow to the exhaust duct. In a further modification, high pressure jets are mounted on the snorkel tube within the water trough to agitate the particulates and solids on the bottom of the water trough to assist in their removal by draining from the trough.

Traveling Hood For Coke Oven Emission Control

View page
US Patent:
40873331, May 2, 1978
Filed:
May 27, 1976
Appl. No.:
5/690415
Inventors:
Roy Naevestad - Fanwood NJ
Assignee:
Wilputte Corporation - New Providence NJ
International Classification:
C10B 2700
C10B 3900
US Classification:
202227
Abstract:
A coke oven emission control system comprising a traveling hood for the quench car into which hot coke is pushed from the coke oven. The hood is independently supported by wheels traveling on rails and is of a length to cover the entire length of the quench car. The hood is moved by the movement of the quench car to and from a quench station, through beams at opposite ends of the quench car that are selectively raised and lowered into and out of a position for engagement with the hood. The top of the hood is provided with a central elongate hollow neck which projects upwardly into a longitudinally slotted exhaust duct paralleling the battery of ovens. The slot in the duct has a pair of parallel extending flexible sealing strips which are biased toward sealing engagement with each other across the slot and which separate to seal on the neck of the hood as it slides longitudinally along the duct. Selective communication is thus provided for flow of fumes, gas, smoke, particulates, etc. from the hood into the exhaust duct from the oven being pushed.
