摘要

The invention relates to a device for the cleaning of a liquor spray nozzle assembly of a soda recovery boiler of the type that includes a liquor supply conduit (3) inserted through an opening (10) in a wall (11) of the soda recovery boiler, which conduit has a mouth (6) from which a plate (8) for distribution of liquor protrudes, more precisely from a lower part of the mouth. The device comprises a scraper means (2) which is movable reciprocally along side edges on the distributing plate (8) by means of a power generator (12) mounted in a supporting stand (13). The scraper means (2) comprises a U-shaped clamp (25) with a bottom piece (26) located under the distributing plate (8) as well as two side pieces (27), which are mutually spaced-apart with a distance which in the main corresponds with the width of the distributing plate.
