Abstract

An assembly for cleaning a smelt spout includes a cleaning head, a drive rod connected with the cleaning head, and a pneumatic or other drive connected to selectively extend or retract the drive rod. The drive rod may be connected with the cleaning head by a pivotal connection. The cleaning head may be bifurcated. The cleaning head may include a leading edge configured to engage and clean a spout opening from which smelt from a chemical reduction furnace flows to the spout. The assembly may further include a pivot point and, as the drive selectively extends the drive rod, torque about the pivot point produced by the cleaning head and an extending portion of the drive rod rotates the cleaning head downward to engage a smelt spout.

Abstract

A nozzle block for a sootblower of the type for cleaning internal heat transfer surfaces of large scale coal fired combustion systems. For cleaning the internal surfaces, a cleaning medium is often used in the form of steam. Due to the cyclical operations and the process of condensation, condensate slugs of water can form in the sootblower fluid flow components. If these slugs are ejected against clean surfaces, undesirable erosion can occur. Several embodiments of nozzle blocks are described each having one or more ejection ports at their distal ends configured to maximize the ejection of condensates while minimizing their cross-sectional area which would diminish nozzle fluidic efficiency. Additional features enhance the ability of the nozzle block to separate and disperse condensate from the slots.
