Abstract

A lance tube for a sootblower device for cleaning internal surfaces of large scale combustion devices. The lance tube includes two sets of nozzles for ejecting fluid cleaning media. A readily accessible fluid flow restriction device is positioned between the two sets of nozzles and accommodates interchangeable plug elements providing different fluid flow restrictions. One set of nozzles is optimized for steam as the cleaning media whereas the other is designed for ejecting water. This lance tube configuration is especially adapted for selectively ejecting steam or water blowing medium as cleaning requirements dictate.
