ABSTRACT:
In order to improve sealing properties between a downcomer and a high-speed layer and in order to efficiently take out produced gas obtained through gasification of, for example, a solid reactant, a syphon for sealing between a downcomer and a high-speed layer through temporary storage of particles moving from the downcomer to the high-speed layer comprises a reactor portion for causing the solid reactant to conduct chemical reaction through action of the particles, a downcomer seal portion in communication, at upper and lower ends thereof, with the downcomer and a lower portion the reactor portion, respectively, a particle outlet seal portion provided in a spaced apart relationship from the downcomer seal portion and in communication, at upper and lower ends thereof, with the high-speed layer and the lower portion of the reactor portion, respectively, and a freeboard portion formed above the reactor portion.
