METHOD AND DEVICE FOR INTRODUCING COAL AND RECYCLING OF SYNTHESIS GAS IN THE PRODUCTION OF SYNTHESIS GAS

摘要

1. The method of introducing a powdery material (C) into a gasification reactor (2), in which the process gas (P) supplied to the gasification reactor (2) is reduced to synthesis gas (S) by means of a powdery material (C), and this powdery the material (C) is introduced into the gasification reactor (2) through the inlet section, while in this section of the inlet for the powdered material (C) negative pressure is created by the Laval nozzle (15), and negative pressure is created, since the process gas (P) passes through the Laval nozzle (15), cast ayuschiysya in that the process gas (P) extends in the gasification space (5) into the gasification reactor (2) .2. The method according to claim 1, characterized in that the powdered material consists of powdered coal (C), and that the secondary reaction product (R) is mixed with this powdered coal (C) when powdered coal (C) is introduced into the gasification reactor (2) .3. The method according to claim 1, characterized in that the negative pressure created at the inlet section sucks in the gases and particles inside the gasification reactor (2), thereby increasing the residence time of these gases and particles in the gasification reactor (2). 4. The method according to claim 2, characterized in that the negative pressure created at the inlet section sucks in the gases and particles inside the gasification reactor (2), thereby increasing the residence time of these gases and particles in the gasification reactor (2) .5. A method according to any one of claims 1 to 4, characterized in that the negative pressure created at the inlet section leads to the circulation of gases and particles in the gasification reactor (2), thereby compensating for differences in concentration in the gas composition, compensating for changes in the rate
