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: 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.
