Cleaning, pneumatic
The whole tubular heat exchanger is cleaned with periodic blasts of
compressed air during operation. The process of cleaning itself is car-
ried out in consecutive blasting of the individual sections. The ash is
removed from the heat exchanger pipes by means of an extremely
short but strong pressure pulse. The device is installed on the back of
the boiler. The compressor should preferably be installed in a cool
place in the boiler room.
The number of cleaning processes within a unit of time (e.g. per hour)
is matched accordingly to the boiler load. An individual, complete
cleaning process comprises a sequence of pressure pulses across all
sections of the heat exchanger.

■ Nozzle part integrated in the flue gas collector; incl. connectors with
heat deflection discs

resistant hoses connected to the nozzle part
