The boiler (2) exhaust gases pass into a filter unit (3) which contains a cleaning liquid in the lower section (6) which a pump (8) returns to a point above one or more filter plates which collect the included dust particles. The cleaning liquid is drained through the plate to rinse the dust from the plates.
