Smokeless and non-recovery type coke oven battery

In a smokeless and non-recovery type battery of coke ovens wherein partially-burned distillation products are conducted from the space above a coal charge in each oven chamber into sole heating flues for combustion therein to heat the floor of the oven chamber and thence the partially-burned distillation products are fed from the sole heating flues into checker-filled systems of ignition chambers coupled to an air supply to incinerate the unburned distillation products for discharge by a means into the atmosphere, the arrangement being such that the sole heating flues of two oven chambers feed partially-burned distillation products into one system of checker-filled ignition chambers, the coke being discharged from each oven chamber through a removable door at the coke side of the coke ovens, the improvement comprising the combination therewith of:

• a downwardly-inclined ramp at the coke side of each oven chamber to support coke discharged therefrom,
• means to discharge a coolant medium for cooling the coke while supported by said ramp,
• a smoke hood including a roof joined with side walls to form an enclosure overlying said ramp to receive smoke and effluent liberated and rising from the coke on the ramp during cooling of the coke, said smoke hood further including partitioning side walls subdividing the space beneath the roof into compartments with a given number of coke ovens and ignition chambers coupled to pairs of these oven chambers, and
• means defining a closable passageway to conduct effluent from each chamber beneath said smoke hood into at least one checker-filled ignition chamber for incineration of the effluent, the closable passageway including a closure member to interrupt communication with the ignition chambers after cooling of coke on said ramp, the arrangement of parts being such that the smoke from the smoke hood undergoes conversion within the ignition chamber to clean hot air.
