soot blowing for large coal fired boiler Agents

Soot Blowing - an overview | ScienceDirect Topics

Soot is a natural byproduct of burning coal. It gradually soils the heating surfaces in coal-fired plants, which inevitably reduces the boiler's efficiency. The obvious solution is to routinely clean the surfaces – a time-consuming and costly process that sometimes isn't absolutely necessary. But there's a better way.

(PDF) Estimation of soot deposition in the boilers of coal

May 09, 2010 · Fossil fuels form the major source of energy for power generation. Coal fired boilers form a major portion of power industry in the world. The inorganic portions of coal vary widely in its behavior during combustion resulting in many forms of operational issues. Steam soot blowers and water lances are used for cleaning the deposits. Only water used for cleaning slagging deposit will be efficient.
