Abstract
A biomass cake pressure-feeding apparatus includes: a screw pump including a first screw with a helical first conveying thread, a second screw with a helical second conveying thread, and a casing accommodating the first screw and the second screw such that the first screw and the second screw are parallel to each other, the screw pump being configured to feed biomass cake to a high pressure reactor, the biomass cake being obtained by adding water to powdery biomass; and a throttle part positioned downstream of the screw pump and configured to form a material seal made of the biomass cake by restricting a flow of the biomass cake.
