Intelligent powder spraying simulation system for coal-fired boiler

The invention discloses an intelligent powder spraying simulation system for a coal-fired boiler, and relates to the field of boiler powder spraying simulation experiments.The intelligent powder spraying simulation system comprises a powder spraying machine, the top end of the powder spraying machine is connected with a heating box for heating pulverized coal, and the top end of the heating box is connected with a first pipeline for conveying the pulverized coal; and one end of the first pipeline is connected with a boiler for combusting pulverized coal and is mounted on an adjusting mechanism, a movable block, a connecting rod and a limiting block. By arranging the adjusting mechanism, the position of a discharging limiting block can be adjusted by rotating a rotating block, one end of the discharging limiting block is made to be close to a discharging port of the first pipeline, the size of an outlet of the discharging port of the first pipeline is adjusted, the smaller the discharging port is, pulverized c
