HYBRID GASIFICATION SYSTEM

摘要

The present invention provides a hybrid gasification system which simultaneously has the advantages of an entrained-flow gasifier using pulverized fuel and a fluidized-bed gasifier utilized for gasifying fuel with relatively various properties. The present intention provides a hybrid gasification system employing a structure in which a second reaction chamber operated at a temperature of 700 to 900 is surrounded by a first reaction chamber operated at temperature, thereby obtaining an insulation effect, performing additional heat exchange, and minimizing a heat loss. Furthermore, the present invention provides a hybrid gasification system having a structure in which unreacted substances and tar within synthetic gas generated from a first reaction chamber reacts within a second reaction chamber, thereby increasing the entire gasification efficiency.

主权项

1. A hybrid gasification system comprising:
a hollow gasifier; a first reaction chamber positioned in the center of the gasifier; a second reaction chamber positioned to surround the first reaction chamber within the gasifier; a first distributor positioned at the bottom of the second reaction chamber; and a synthetic gas transfer part positioned at the bottom of the first and second reaction chambers, wherein pulverized fuel introduced into the first reaction chamber through a pulverized fuel injection pipe is converted into synthetic gas through the first reaction chamber, and the synthetic gas generated from the first reaction chamber is introduced to the second reaction chamber through the first distributor.
