Steam soot blower capable of controlling steam for concentrated spraying

The invention relates to the field of steam soot blowing, in particular to a steam soot blower capable of controlling steam for concentrated spraying. The steam soot blower is characterized by comprising a steam soot blowing pipe and a program-controlled device, multiple soot blowing holes which can be opened and closed are formed in the pipe wall of the steam soot blowing pipe, and three soot blowing hole retaining plates are obliquely arranged on the periphery of a position, corresponding to the soot blowing holes, on the outer side of the pipe wall. When steam enters the steam soot blowing pipe, a hole cover of each soot blowing hole is opened towards the outer side of the pipe wall to be fixed, each hole cover and the corresponding soot blowing hole retaining plate obliquely arranged on the outer side of the pipe wall form a trapezoidal space, and a spiral guide pipe is mounted at the upper end of each soot blowing hole retaining plate and disposed in the trapezoidal space formed by the soot blowing hole
