Apparatus and method of deslagging a boiler with an explosive blastwave and kinetic energy

Abstract

An apparatus for deslagging a steam boiler includes a plurality of loop clusters of detonating cord, each including a plurality of loops arranged in a multi-directional pattern to impart a three-dimensional generally spheroid shaped to the cluster The clusters are supported in spaced apart relation between a pair of adjacent tubing panels and are interconnected by lengths of detonating cord to form an explosive assembly adapted for substantially simultaneous detonation. A plurality of explosive assemblies are arranged in approximately every third or fourth spread between tubing panels and are interconnected so as to pyrotechnically detonate each explosive assembly after a predetermined delay in response to detonation of another explosive assembly to which it is connected. The invention is further directed to the method of deslagging a steam boiler with the plurality of loop clusters of the invention.
