soot blowing for large coal fired boilers


Soft-computing models for soot-blowing optimization in ...

Abstract. Fouling and slagging are classical difficulties in pulverized fuel utility boilers which cause important degradation and dramatic reduction of efficiency. Current cleaning devices traditionally based on prefixed soot-blowing manoeuvres mitigate the problem only

Optimized steam sootblowing | Heat Management

Sootblow more with less steam. More than 90% of the cleaning by a sootblower takes place during the sootblowers initial stroke. When the sootblower is retracted 50% of the steam is used unnecessarily at the same time as the soft ash is sintered into concrete-like deposits. With HISS (High Impact Sootblowing System) several sootblowers can be operated in parallel with or without return steam i.e. more

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.

Soot Blowing - an overview | ScienceDirect Topics

Feb 10 2011 · Soot blowing is most commonly carried out using dry saturated or slightly superheated steam at boiler pressure. The use of dry saturated steam generally has a better impact effect in removing deposits than superheated steam but precautions must be taken to preclude slugs of water from entering the boiler flueways.

Soot Blowers |

In very large coal-fired boilers air blowing is preferred as the soot blowing consumes high-quality expensive water. For air blowing an elaborate arrangement consisting of a proper air compressor station to deliver high-pressure air between 25 and 35 barg (350 to 500 psig) with all redundancies controls and safeties is required which is reasonably expensive.
