Abstract: A combined soot blower and liquid projector for cleaning boiler surfaces has a main lance tube telescopically overfitted on a feed tube and carrying a nozzle assembly at its outer end for projecting steam and/or air supplied through said tubes, a second pair of telescoped tubes inside and substantially smaller in diameter than the two tubes first mentioned and including a slidable liquid lance having a jet member connected to the nozzle assembly to discharge liquid at right angles to the stream or air. During projection of liquid, steam and/or air is supplied to the outer tubes to cool them and the nozzle assembly.
