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.
