SYSTEM OF INTERCYCLE GASIFICATION OF SOLID FUEL INVOLVING INDUSTRY PRODUCTION OF COKE Russian patent published in 2006 - IPC C10B49/02 C10J3/04 C10J3/20 

FIELD: power engineering.

SUBSTANCE: system of intercycle gasification of solid fuel for combined-cycle plants comprising at least one upright layered-type gas generator (1) with lances (1.1) for air and steam blast further includes upright pyrolyzer (2) combined with all gas generators (1) in its upper portion through common portion (3) of bodies of pyrolyzer (2) and gas generators (1) and connected in this part with each gas generator (1) in parallel regarding entering fuel and generator gas. Lances (1.1) for air and steam blast of each gas generator (1) are constructed in the form of combined block ejector (4) installed on air-supply line, to inlet side of which is connected line (5) serving to suck off moisture vapor from superlayer space (5) of common portion (3) of bodies. In addition, in lower portion of body of pyrolyzer (2), saturated steam blast lances (2.1) are installed and, in the same portion of the body of pyrolyzer (2) above lances (2.1), there is collector (2.2) for withdrawal of mixed generator-pyrolysis gas.

EFFECT: enabled production of commercial coal char.
