Abstract

A method and apparatus for deslagging boilers, wherein a quenching-type stream of water is first applied to the outer surface of the hot slag to induce the formation of fissures by embrittlement and contraction, and thereafter the fissured surface of the slag is impacted by a high velocity pulsed jet which drives water into the fissures, whereby dislodging of the slag is aided by the expansive force of water which vaporizes in the fissures. A soot blower lance is illustrated, equipped with dual liquid supply and projecting means, and pulsing mechanism for interrupting the flow of blowing medium to one of the projecting means, to create the pulsed jet. The lance is moved in a pattern to subject the slag successively to a lower pressure stream and then to the higher pressure pulsed stream. <IMAGE>
