2005-11-15 · Soot blowing was still necessary, but net fuel savings were available through minimizing the net amount of excess air. I would attack the problem through optimizing the combustion process for slag minimization first. Then, soot blowing can then be more effectively minimized. As noted previously, soot blowing is a very costly process.

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 …

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.

2020-5-8 · Soot blowing Cycles and Considerations A cleaning cycle is a period of time in which required blowers are cycled in a pre-arranged sequence to clean given areas of a boiler over a period of time. Many variables are intermeshed in determining a cycle, some of which are:

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.

Cited by: 1Cleaning medium – the substance used to clean soot or ash buildup on boiler tubes. The cleaning medium may be saturated steam, superheated steam, compressed air, water or a combination of these. Saturated steam is the most widely used medium because: Boiler-generated steam avoids the cost and maintenance of a compressor

soot blowing for large coal fired boilers. Soot blower installed for coal fired boiler - SOOT BLOWER . The boiler is designed by Poster Wheeler company in US. It is subcritical, natural circulation, single drum, coal fired 2020tph boiler. 100 sets of soot blower is installed for each boiler. 4 …

In The Efficient Use of Energy (Second Edition), 1982. Steam Soot-blowers. 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.
