NOVELTY - Counter flow agitating pyrolysis gasifier reactor comprises agitator (5) which is disposed right below drying zone and ensures regular dispersion of fuel within reactor; pyrolysis zone (4) provided alongside the agitator; tubes (6) for enabling passage of air and diffusion within the agitator; upper oxidation zone agitating air diffusion holes (11) for injecting air using tubes; an air diffusion passage provided below passage zone (8) and forming upper section of reduction zone (9); and air inlet holes (10) providing air to lower passage forming lower section of the reduction zone.    USE - Counter flow agitating pyrolysis gasifier reactor for use in pyrolysis and gasification of biomasses, all kinds of fossil wastes, intense carbon containing combustible and inflammable industrial wastes.    ADVANTAGE - The counter flow pyrolysis gasifier reactor has internal agitator that ensures regular distribution of fuel in the oxidation and gasification zones during production of various combustible gases by pyrolysis and gasification of all kinds of fossil based sources and other wastes. It provides perpetuate oxidation by preventing bridging in the oxidation zone and to ensure that air reaches into the fuel at the oxidation zone by of the agitator, oxidation speed is increased and the agitator is allowed to be cooled.    DETAILED DESCRIPTION - Counter flow agitating pyrolysis gasifier reactor (1) comprises:    (A) fuel feeder (2) and a valve helix that enables input to the feeder;    (B) drying zone (3), an agitation system (7), a fuel feeder on the reactor, and a passage zone (8) where the oxidation occurs;    (C) upper passage (12) that narrows down and twines like a cone to facilitate fuel flow, an upper passage air gap (13) located between the inner part and the outer wall of the reactor enabling receipt of the air supplied to the air inlet holes (10) into the reactor, and an upper main air inlet valve (14) which enables air to be accepted to the air gap;    (D) agitator air inlet tube (15), an agitator air inlet valve (18) to provide air intake, a conical lower passage zone (16) which reaches a reduction zone (9) by extending inwards and downwards, and gas outlet tubes (17) on the outer wall which enable collection of the product gas surrounding the reduction zone;    (E) second passage (19) forming the lower part of the reduction zone enabling the ashes resulting after gasification to flow and accumulate, and lower passage air gap (20) at which intake of air is realized by air inlet valve (21);    (F) ash discharge helix (22) air insulated from the lowermost point of the reactor, and an air insulation valve (23) by which the ash-slag mixture remaining at the end of the gasification process is discharged;    (G) agitator (5) which is disposed right below the drying zone and ensures regular dispersion of the fuel within the reactor, a pyrolysis zone (4) provided alongside the agitator, and tubes (6) within the agitator system enabling passage of air and diffusion within the agitator;    (H) upper oxidation zone agitating air diffusion holes for injecting air by the tubes, an air diffusion passage which is provided below the passage zone and which forms the upper section of the reduction zone; and    (I) air inlet holes for providing air to the lower passage forming the lower section of the reduction zone.
