Gives advice on writing technical specification for procurement of sootblower apparatus for steam generating plants used in power stations. Does not cover apparatus used in the nuclear reactor area of nuclear power stations. Applies to mechanical, steam or air, and acoustic sootblowers for furnace wall sootblowers and water lances, rotating element (including rake) sottblowers, air- heater sootblowers and long retractable and semi-retractable sootblowers. Apparatus is specified by function rather than design type. So the guidance is specified in terms of performance, rather than a detailed outline of apparatus to be supplied.
