Steam soot blowing
A steam soot blower consists of a number of nozzles on a pipe that rotate and
sometimes moves axially between the banks of tubes.
Designed to be used during boiler operation.
This example is an
exhaust gas boiler but the same method can be used for an
oil fired
steam boiler.
If you don't care about your boiler then the smoke-tubes might end up like
this. Many hours of work to clean up the tubes manually will be the only
solution.
In this particular case the furnace pressure had increased so the combustion
air fan didn't manage to blow in sufficient air for the combustion of the fuel
oil and hence more soot was formed.
