Abstract: A large-scale coking reactor including a housing provided with a chamber and with outer and inner chamber frames, a displaceable outer door elastically compressed against the outer frame and formed with a respective elastic peripheral seal compressible against the frame and with an outer high temperature membrane interposed between the door and the seal and elastically pressed thereagainst to seal the door opening, a displaceable inner door spaced from the outer door and formed with an inner high temperature membrane interposed between the inner door and the inner frame to fit elastically the inner frame, the inner and outer doors being releasably interconnected upon displacing the outer door, so that the doors are mounted in the housing to be operatable either selectively or in combination with one another.

Abstract: A door is equipped on its side facing the area to be closed off, with a sealing element disposed around the peripheral edges of the door, a door locking device to retain the door in a closed position, and possibly a thermal layer for insulating the door from passage of heat therethrough.

Abstract: The door has a separate seal element and a hollow profile frame. The hollow profile frame has a number of tappets exending therefrom to press the seal element against a door frame. These tappets are applied individually to the seal element by pressure from a pneumatic hose within the hollow profile frame which applies pressure to the tappets.

Abstract: The heating flues in an oven are equipped with refractory components to control the feed and mixture of combustion air and gas into each heating flue. In one embodiment, the refractory component forms a plurality of passageways through which air and gas flow into mixture. Initially, the gas is mixed with small amounts of air to obtain substoichiometric combustion in the refractory component. Additional combustion air is supplied to the resulting partially combusted gases and unburned gas to complete the combustion of air and gas in the heating flue. This arrangement serves to optimize the flame control and the heat discharge over the height of the heating flue. In a second embodiment, the refractory component forms a plurality of passageways through which combustion air is supplied to the gas along the passageway outlets which are located at preselected positions along the length of the heating flue.

Abstract: The door has a separate seal element and a hollow profile frame. The hollow profile frame has a number of tappets extending therefrom to press the seal element against a door frame. These tappets are applied individually to the seal element by pressure from a pneumatic hose within the hollow profile frame which applies pressure to the tappets.

Abstract: Coking system, wherein the coking blends particularly based on hard coal, are fed batchwise to a reactor (1), which is heated indirectly by heat recovery in regenerators (I, II) or recuperators, whereby the reactor is built as a high-capacity coking reactor (100), several high-capacity coking reactors are combined to form a reactor block and the high-capacity coking reactors are built as mutually independent modules, whereby each module can be operated or optionally replaced independently of the neighboring modules, with little or no impairment of the operation of the neighboring modules. The individual reactors are independently operatable in terms of statics and heat supply. The regenerators, or recuperators (I, II, R, R') can be arranged laterally or underneath the reactor chamber. Neighboring reactors can have a common intermediate wall (2). The reactor chambers have a width of at least 0.7 m, a height of at least 8.5 m and a length of at least 18 m.
