Title:
SUPERCRITICAL WATER GASIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/217399
Kind Code:
A1
Abstract:
In the present invention, a first heat exchanger 130 preheats a slurry body including a water-containing biomass by using steam from a drum type boiler 140, thereby making it possible to minimize the fuel cost, reduce the size of the first heat exchanger 130, suppress the generation of tar and char, prevent the piping of the first heat exchanger 130 from blocking, and more efficiently generate a fuel gas. Further, when preheating is performed, a flow rate adjusting valve 160 adjusts the flow rate of the steam to control the temperature of the slurry body at the outlet of the first heat exchanger 130, thereby making it possible to avoid insufficient increase in temperature of the slurry body at the outlet of the first heat exchanger 130. Therefore, the present invention can eliminate the heater provided between the first heat exchanger 130 and a gasification reactor 141 in the conventional system.
