Title: Fuel feeder of fluidized bed furnace
Inventor: ITOU YUKIYA
IPC: F23K3/14
Filed: 1981-12-10
Abstract: PURPOSE:To enable evenly dispersed feeding of fuel into a furfance, even a relatively large furnace with a simple equipment by feeding the fuel evenly into the furnace through a fuel feed tube from a screw feeder. CONSTITUTION:Fuel of a hopper 19 is fed to an inlet 14 via a rotary valve 20.
