1.7.1 - Sootblower
Sootblowers are applied where combustion can foul to the degree where it is not cost effective to
manually open inspection doors and physically clean the exchanger by other means.
Typically diesel, No. 2 oil, and No. 6 oil having multiple coils with proper fin spacing can be used in
conjunction with a sootblower assembly. A single row design or a maximum of three coils (square
pitch design), in conjunction with the proper sootblower will ensure the best possible solution to
achieve a nearly soot free exchanger.
The sootblower assembly surrounds the outside of the core or coil area. When operated, the
particulate is blown off into the flue gas stream. The internal bypass damper must be in the open
position during blowdown. A routine blowdown schedule should be established at time intervals
consistent with the soot loading characteristics of the fuel being burned. For example, on a boiler
burning No. 2 oil, a daily blowdown may be all that is required. If the primary fuel is No. 6, then the
sootblower should be used at a time interval consistent with the normal boiler blowdown.
All Sootblowers are designed to utilize high pressure air or steam at 50 psig minimum -100 psig
maximum rating. It should be noted that no Sootblower can provide 100% cleaning ability, but they
can definitely minimize the need for manual cleaning. For heavy oil or incinerator-type atmospheres,
periodic manual cleaning of the heat exchanger surface will be required to insure maximum efficiency
capability.
