Abstract
The disclosure belongs to the technical field of solid fuel utilization and discloses a gasification reactor adaptable for feedstock with wide particle size distribution, including a reactor body. The reactor body is composed of a first reaction chamber, a second reaction chamber, and a third reaction chamber, which are connected with each other. The side wall of the first reaction chamber is provided with a first vent for introducing a gasification agent to fluidize the fine feedstock particles in the first reaction chamber and the gasification reaction occurs. The bottom of the second reaction chamber is provided with a second vent for introducing an oxidant to react with the coarse feedstock particles in the second reaction chamber. The bottom of the third reaction chamber is provided with a third vent for introducing a gasification agent to fluidize and gasify the incompletely reacted particles in the third reaction chamber.
