The utility model discloses a
biomass fuel feeding device and a
combustion system, and relates to the technical field of
biomass combustion device optimization. The material lifting device comprises an inclined material lifting device body, the top end of the material lifting device body serves as a discharging end and is communicated with a vertically-downward first material
pipe, the bottom end of the first material
pipe is communicated with a downwards-inclined second material
pipe, the bottom end of the second material pipe serves as a discharging port, an
air blower is installed on the side wall of the first material pipe, and the
air blower is installed on the side wall of the second material pipe. An air blowing opening of the
air blower is horizontally formed, the air blower is arranged at the corner communicating position of the first material pipe and the second material pipe, and the air blowing opening of the air blower is communicated with a material channel formed by communicating the first material pipe and the second material pipe; the purposes that slow feeding can be adapted, and meanwhile blockage caused by untimely discharging is avoided during rapid feeding are achieved.
