Heating system for regenerative coke ovens

Light construction plug for coke oven doors

An immersion type seal for a standpipe opening of a coke oven comprises a standpipe which has a top part with top opening and an encircling rim around the opening which is closed by a standpipe lid and an annular seal frame interposed between the lid and the opening. The seal frame includes a lower peripheral edge which is of spherical shape which is seated on a ring disposed over the rim of the standpipe top opening and the seal frame is advantageously adjusted on the seating ring and clamped by means of tie rods which are disposed at spaced locations around the periphery of a flange portion of the seal frame. The tie rods are clamped between flanges of a top piece of the standpipe and the standpipe itself and the flange of the seal frame. The seal frame also defines an open top trough which defines a water seal and the standpipe lid includes an annular wall portion which extends into the trough. The standpipe lid also advantageously includes an inner annular wall portion which is adapted to seat on a ledge portion of the annular sealing frame.

Immersion-type seal for the standpipe opening of coke ovens

A device for separating gases and solids, particularly coal dust, during the carbonization of coal, particularly predried and preheated fine coal in coke ovens arranged in a battery which includes a standpipe extending upwardly from the top of the battery having a bend extending from the top of the standpipe downwardly into a collecting main, comprises, a vertically extending standpipe which extends upwardly from the top of the battery and has a bend at the top thereof extending outwardly and downwardly from the top and which includes a longitudinally extending collecting main connected into the lower end of the bend with a solids discharge line overlying the bend and extending substantially parallel to the collecting main. The solids matter discharge line includes a connection extending downwardly into the bend. Means are provided for spraying a liquid into the bend over the collecting line and the solids matter discharge line includes a shutoff control in the connection to the bend. Exhauster means are connected to the solids matter discharge line for exhausting the gases enriched with the solids to a combustion furnace where they are burned. The combustion furnace may be one which heats water to form steam which is supplied back into the collecting line. Some of the solids which are removed are directed to a cyclone separator where coal dust is separated therefrom and the gas is returned to the collecting line. With the method of the invention, the bend is selectively connected to the solids matter discharge line so that gases containing solids are withdrawn therefrom and part of them are directed to a separator to remove the coal dust solids and to return the gases to the collecting main and other parts are directed to the furnace for burning therein.
