Best Practice Guidelines for Boiler Soot Blowing Utilities have been cleaning their boilers for many years using either steam or high-pressure air. In the past, when air was used, due to the size of the boilers and the reasonable quality of fuel used, a relatively small
Coal fired boiler. Using coal as fuel in order to create energy in the form of electricity and/or heat is very common in the world. The coal comes in many different qualities, and often generate problems with ash fouling. The stricter limits for emissions, also create new challenges for the boilers, such as difficulties with build ups in heat

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.
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
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
2015/3/5 · Thus, the objective of soot-blowing optimization in coal-fired boiler is to predict the optimal times to start the individual cleaning units for the various heat traps. Many factors affect the optimal soot-blowing schedule and must be considered in any optimization scheme.

2014/4/14 · Intelligent soot blowing systems also only clean when necessary, which avoids boiler tube erosion. "Basic systems are blind to what's going on inside the boiler," Martin said.
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 …
