Equipment for collecting, extracting and purifying foul gases arising on the coke side of a battery of chamber coke-ovens with vertical flue

In equipment for collecting, extracting, and purifying gases arising on the coke side of a battery of coke oven chambers with vertical heating flues, and wherein said equipment includes:

• gas gallery track means parallel to and alongside said chambers;
• a coke batch-conveying truck movable on said gas gallery track means alongside said chambers and having a door-lifting and cleaning device and a coke batch guide which is movable on the truck in the directions both parallel and transverse to the movement of said truck alongside said chambers;
• a quench train having a locomotive and a quench truck movable alongside said chambers;
• a hood overhanging the loading area of the quench truck and movable alongside said chambers;
• a stationary gas extracting and purifying device;
• a gas collection duct arranged parallel to said chambers and connected to said stationary gas extracting and purifying device, said gas collection duct defining a longitudinally extending opening, said opening covered by an elastic cover belt which is liftable from said gas collection duct opening;
• and a gas transfer device connected to said hood and movable on said gas collection duct under said belt for lifting said belt from said gas collection duct opening thereby effecting transfer of said gases from said hood to said collection duct;
• the improvement comprising:
• track means on said gas collection duct;
• frame means for carrying said hood and extending substantially horizontally, said frame means being supported at three spaced-apart points;
• and
• first, second, and third wheel means, one wheel means at each of said three support points for supporting said frame, said first wheel means being mounted for movement along said gas gallery track means and said second and third wheel means being mounted for movement along said gas collection duct track means, the distance of said frame support point on said gas gallery track means from the line joining said other two frame support points on said gas collection duct track means being less than the distance between said other two frame support points on said gas collection duct track means.
