Abstract

Two-stage combined cocurrent-countercurrent gasifier, which is used for the thermochemical process that converts solid carbonaceous materials into combustible gases, has as first (pyrolysis) stage a countercurrent reactor (1) placed above the second (gasification) stage which is a cocurrent reactor (2) and is characterized in that between the two stages a diaphragm (3) is present, which cuts off the gaseous flow between the countercurrent reactor (1) and the cocurrent reactor (2), while allowing the solid pieces falling from the countercurrent reactor (1) to pass to the cocurrent reactor (2). From the measurements of the physical parameters at the discharge (11) of the pyrolysis gases (vapor, volatiles) we have an immediate image of the composition and/or the humidity of the new incoming fuel, thus the automatic control and the safe operation of the process are achieved by setting the air and/or fuel feed of the countercurrent reactor. Thereby variations in the composition and/or humidity of the incoming fuel are balanced and settled quantities of charcoal and gases are supplied to the next process stages, thus it is easy to control all the gasification process. The burning torch (12) of gases coming from the countercurrent reactor (1), is placed so that to introduce the flame into the cocurrent reactor (2) by horizontal setting. The upper part (14) of the cocurrent reactor (2) is configured so that to expand the flue gases of the burning torch (12) by cyclonic mode.
