A horizontal gasifier features a closed body (3) with thermal insulation containing a helical feed screw (4) for the feedstock (2), a vertical feed inlet (1) for the feedstock (2) located at one end of the body (3), an inlet (7) for the oxidizing gas (6), and an ash collector (5) at the other end of the body (3), and an outlet (9) for volatile products (8). The gasifier is characterized by a gasification zone (21) in the final section of the body (3), with the shaft (4b) of the helical feeder (4) being completely hollow along its length and equipped with inlet openings (18) for introducing a supplementary portion of oxidizing gas (6) located in a segment extending beyond the body (3) on the side where the feed inlet (1) is located, and outlet openings (20) for this portion of oxidizing gas located in the gasification zone (21).
A horizontal gasifier with a closed body (3) equipped with thermal insulation, wherein a helical feed screw (4) for feedstock (2) is located, equipped with a vertical feed inlet (1) for feedstock (2) positioned at one end of the body (3), an inlet (7) for oxidizing gas (6), and an ash collector (5) located at the other end of the body (3), an outlet (9) for volatile products (8), and at least two flow meters and at least two temperature sensors, characterized in that the final zone of the body (3) forms a gasification zone (21), and the shaft (4b) of the helical feeder (4) is completely hollow along its length and equipped with inlet openings (18) for introducing a supplementary portion of oxidizing gas (6) located in a segment extending beyond the body (3) on the side where the feed inlet (1) is located and outlet openings (20) for this portion of oxidizing gas located in the gasification zone (21), and the outlet (9) for volatile products (8) is located between the feed inlet (1) and the oxidizing gas inlet (7), and the inlets (7) and (18) for oxidizing gas (6) are equipped with independent mass flow meters (6a) and (6b) connected to at least two temperature sensors (23) located in the body (3).
A method for the thermochemical conversion of carbonaceous combustible material (2) in a horizontal gasifier, in a counter-current process, comprising feeding the carbonaceous material (2) into the body (3) of the gasifier through a vertical feed inlet (1) and moving it using a horizontal helical feeder (4) towards the end of the body (3), where a gasification zone (21) is located, while simultaneously supplying oxidizing gas (6) in a counter-current arrangement, and collecting solid product (11) at the end of the body opposite the feed inlet (1) for the feedstock (2), characterized in that a part of the oxidizing gas (6) is supplied through an inlet opening (7) located at the end of the body (3) near the gasification zone (21), and a supplementary portion of the oxidizing gas (6) is supplied from the side of the body (3) through a flow meter (6a) located at the vertical feed inlet (1) via a sealed conduit (4b) with at least one inlet opening (18) at one end of the conduit (4b) and outlet openings (20) at the end located in the gasification zone (21), and the resulting volatile products (8) are discharged through an outlet nozzle (9) located in the upper cover (3a) of the central part of the body (3).
