Cleaning Boiler Firesides and Watersidex - tpub.com

However, because cold water does not clean satisfactorily, you have to maintain the water temperature as close as 150 degrees as possible. A water pressure of 200 to 250 psig should be provided at the cleaning lances or soot blowers. The water jets must penetrate the tube banks and strike with enough force to break up the slag accumulations.

Turbulators | CleanBoiler.org

Turbulators are a substitute for a more costly economizer or air-preheater. They are simple, easy to install, and low cost. Their installed cost is about $10 to $15 per boiler tube. Current turbulator designs do not cause significant increase in pressure drops or contribute to soot formation in natural-gas-fired boilers.
