Coke car with fume-collecting hood
Abstract
Abstract A TUBULAR COKE GUIDE IS DISPOSED BETWEEN THE FRONT OF A BATTERY OF COKE OVENS AND A CAR THAT RECEIVES COKE DISCHARGED FROM THE OVENS THROUGH THE GUIDE. ABOVE THE CAR THERE IS A FUME-COLLECTING HOOD, THE SIDE OF WHICH ADJACENT THE COKE GUIDE IS FORMED FROM A PLURALITY OF PLATES PIVOTALLY SUSPENDED FROM THEIR UPPER ENDS ON A HORIZONTAL AXIS IN EDGE-TO-EDGE RELATION. AS THE CAR IS MOVED ALONG THE BATTERY OF OVENS, EACH PLATE IN SUCCESSION, AS IT COMES OPPOSITE THE OUTLET OF THE COKE GUIDE, IS SWUNG INWARDLY TO PERMIT COKE TO BE DISCHARGED FROM THE GUIDE INTO THE CAR. THE FUME THAT IS PRODUCED IN THE HOOD BY THE COKE IS DRAWN OUT BY AN EXHAUST SYSTEM AND RENDERED NON-POLLUTING BEFORE IT IS DELIVERED TO THE ATMOSPHERE. D R A W I N G
