2011/3/1 · Intelligent soot-blowing (ISB) must be a combination of modelling, soft-computing techniques and on-line systems to monitor the boiler performance. Consulting companies and some boiler manufactures have developed automatic systems with the goal of optimizing soot-blowing.

1.1 Bituminous And Subbituminous Coal Combustion

reduction varies considerably depending on boiler type, fuel, and boiler operation. Soot blowing is also a source of intermittent PM emissions in coal-fired boilers. Steam soot and air soot blowing is periodically used to dislodge ash from heat transfer surfaces in

Why in coal fired steam boiler soot blowing source is always from …

Answer (1 of 2): This is only a guess, but I believe it is because you can maintain steam flow through the superheater when the boiler is still being fired. If you took saturated steam from the generating coils, or drum, there would be no cooling flow through the

This paper presents a comprehensive approach for optimization of soot-blowing of air preheaters in a coal-fired power plant boiler. In the method, modeling of the cleanliness factor is firstly proposed to monitor the ash deposition status of the air preheaters. Then, the statistical fitting of the ash fouling status is subsequently obtained to analyze the ash fouling dynamics and …
