Sootblower and Boiler Cleaning Terminology, Principles and Applications

Deposits are removed from the corrugated heating surface by means similar to SCR catalyst cleaning applications such as straight-line sootblower. Swing arm sootblowers and dual media cleaning devices can also be used. Cleaning media must be aimed directly at the gas inlet face of the heating surface with relatively low velocities.

Boiler Operations That Affect Efficiency (Part 2)

Adjustments can typically vary the turbulence and flow rates in burners. Increased turbulence increases the air-fuel mixing. It also increases the combustion intensity, provides faster heat release, reduces unburned carbon (UBC) in the ash, permits operation with less excess air, and increases boiler efficiency.
