Jul 20, 2017 · 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
Soot-blowing steam can be extracted from high pressure (HP) steam leaving the first superheater and then reduced to a suitable pressure of 2–3 MPa or extracted from the steam turbine. Soot-blowing steam demand is 2.5–4% of HP steam generated. In older boilers, soot-blowing requirements can reach 10% of generated steam.
One of the big questions we receive is about burning coal in an outdoor wood boiler. An outdoor wood and coal boiler no longer exists due to the new EPA regulations that were passed in February of 2015. If you burn wood in one of our coal boilers you will void the warranty.

The use of the soot blower can improve the operating cycle of the boiler, especially the burning of inferior coal, various biological straws, garbage waste, etc. Due to the large viscosity of the ash produced, the boiler runs for a period of time, making the load lower and lower. In the case of normal soot blowing in the boiler, such
In a typical coal fired power plant, the rotary regenerative air heater is responsible for between 5 percent and 10 percent of the boiler’s total efficiency, thus making it a critical component

Downloadable! 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
For oil-fired boilers, the daily dosage depends on the fuel oil consumption per boiler, per day (see table). For coal-fired boilers, the approximate daily dosage is 3 kg. of SOOT REMOVER per 30 tonnes of coal consumed per boiler every 24 hours. Note: for best results apply SOOT STICKS SOOT REMOVER daily, immediately after soot blowing. PACKAGING

What Are the Causes of Boiler Soot?. Soot is a fact of life for those of us who operate a gas- or oil-burning boiler. A little bit of soot is normal, but excessive soot production could indicate a problem with the way your boiler is operating. Large amounts of soot inhibit heat transfer, which forces your boiler to work harder than it needs to and
