ABSTRACT:
A method and apparatus for deslagging boilers and the like while steaming, 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 of the slag and thereafter while the fissures are still present 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 generally conventional blower 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.
