The invention discloses a
biomass boiler feeding
system, and belongs to the field of
biomass boilers. According to the
biomass boiler feeding
system, the bottom of a stock bin and a secondary spiral feeder are installed in a communicating and matched mode, the secondary spiral feeder and a feeding
pipe are installed in a communicating and matched mode, the feeding
pipe and a discharging
pipe are installed in a communicating and matched mode, the discharging pipe and a
hearth are installed in a communicating and matched mode, an air bellow is installed in a communicating and matched mode with the feeding pipe and the discharging pipe, a pneumatic quick shut-off valve, a heavy hammer type lever valve and a
metal expansion joint are sequentially installed on the feeding pipe in a matched mode from top to bottom, a
fluidization air bellow is installed at the bottom of the discharging pipe in a matched mode, the
fluidization air bellow and an air bellow communicate and are installed in a matched mode, and the air bellow and a draught fan are installed in a matched mode. The
biomass boiler feeding
system aims to solve the problem that a unit cannot run for a long period due to material blockage, shaft breakage and shaftless spiral breakage of a stokehole feeding system of a power
plant in the current biomass industry, reduce the labor intensity of operators, save
electricity and reduce the production cost, the one-time
investment cost, the repeated
investment cost and the maintenance cost are saved, and meanwhile the target of long-period operation of the unit is achieved.
