Numerical study of optimizing feeding methods of supercritical water fluidized bed reactor

SCWFBR (Supercritical Water Fluidized Bed Reactor) is a new concept for hydrogen production by biomass gasification, which can effectively prevent the reactor plugging and improve the biomass gasification efficiency. Feeding pipe, which is a necessary component for biomass continuous gasification, has great effect upon solid particles distribution and gasification process in SCWFBR. A reasonable evaluation criterion was determined for optimization design of feeding pipe mouth structures in the paper. Influences of feeding mode and operating methods on solid particles distribution were studied by numerical simulation. The purpose was to provide reference for the development of SCWFBR design theory.
