TRANSCRIPT
Questionaire first meeting
Power and Heating PlantPower and Heating Plants can benefit from both Infrasound Cleaning and Steam Optimization.Therefor it is important to find out what product range to target.As a general rule: HISS in areas over 550˚ C, Infrasound in areas less than 550˚ C. But there are overlaps, see picture 1.
If you can, try to find a schematic drawing of the boiler. It is very helpful at discussions.There will nearly always be a poster on site showing the boiler. One possibility is to take a photo of it (ask for permission first) so it can be used at discussions later.In worst case use one of below schematic views during discussion.
Ask the customer to describe what kind of boiler it is:
Built Year -Size (MW heat, MW power) -Type (CFB, BFB, Roaster etc) -Fuel (Coal, Pellets, wood etc) and moisture -Number of ECO, SCR, ESP -No of Soot blowers -Brand of Soot blowers -Brand and model of DCS (ABB etc) -Period in use (24/7, 365 d/year?) -At what % load is the boiler operated? Power generated? -Is operation stable? Need for tuning due to rising flue gas temp? -
How is cleaning performed (manually, soot blowing etc) -How often do they clean with steam (can vary in different areas) -How long does a cleaning (steam) cycle take -How much steam is used for cleaning -Do they know ∆P and ∆T before/after cleaning -

How many planned stops per year -The reason for stopping -What area do they need to clean most often -How, how often and why do they clean ECO -How, how often and why do they clean SCR -Do they have large ammonia slip compared to other sites? -
Have they exchanged the ECO -Do they have problem with corrosion -How often do they need to change tubes -Do they have condensate issues? -
Temp at Superheaters -Temp at ECO -Temp at APHTemp at SCR -
Biggest concerns regarding sootingWearuse of steam,can’t soot enough - Where?change of load, have to compensate load for turbinpre-heating of steam pipes other
