Coal water slurry feeding device for multi-flow circulating fluidized bed boiler

The invention discloses a coal water slurry feeding device for a multi-flow circulating fluidized bed boiler, and relates to the technical field of boilers, the coal water slurry feeding device comprises a slurry spraying box and a slurry supply pipe, the right side of the slurry supply pipe is provided with a discharging plate, the right side of the discharging plate is provided with a moving frame, the right side end of the slurry spraying box is provided with a spraying hole, and an adjusting assembly is arranged in the spraying hole. According to the coal water slurry feeding device for the multi-flow circulating fluidized bed boiler, through strong thrust generated by rotation of the hydraulic blades, the output power of the spray holes is improved, and sprayed coal water slurry obtains larger thrust, so that the working efficiency is remarkably improved; through movement of a third toothed bar and accurate control of a control rod and an adjusting plate, an operator can flexibly adjust the injection spe
