A second pipe conduit system connects each water spraying unit compressed air connection to a common compressed air source. Each water spraying unit incorporates at least one separate water mouthpiece (2) with a water outlet channel (26), which is connected with the water spraying unit water connection (17) and issues into a water outlet opening (29). For each water mouthpiece a separate compressed air mouthpiece (3) has an air outlet channel (23), which is connected with the water spraying unit compressed air connection (10), which is directed towards the water outlet channel water outlet opening and across the water outlet channel. |
