Abstract

Polttokattila, joka käsittää savukaasukanavan ja lämmönvaihdinputkia savukaasukanavassa (132, 212, 262) nesteen, höyryn tai ilman lämmittämiseksi tai esilämmittämiseksi. Polttokattila käsittää ensimmäisen oleellisesti savukaasujen virtaussuuntaisen tasomaisen äänenvaimenninlevyn (320), joka ensimmäinen äänenvaimenninlevy (320) käsittää ääntä absorboivaa materiaalia ja mainittu ensimmäinen äänenvaimenninlevy (320) sijaitsee mainitussa savukaasukanavassa savukaasujen virtaussuunnassa jonkin mainitun lämmönvaihdinputken (132, 212, 262) jälkeen, jolloin äänenvaimenninlevy vaimentaa savukaasujen virtauksen pyörteisyydestä aiheutuvaa melua. Äänenvaimenninlevy (320) voi sijaita välittömästi tai lähes välittömästi lämmönvaihdinputken (132, 212, 262) jälkeen. Lisäksi polttokattila voi käsittää värähtelyn estolevyn (600), joka on oleellisesti savukaasujen virtaussuunnan suuntainen tasomainen levy, ja joka värähtelyn estolevy (600) jää savukaasujen virtaussuuntaa vastaan kohtisuorassa suunnassa kahden lämmönvaihdinputken 15 (132, 212, 262) väliin savukaasukanavan lämmönvaihdinalueen resonanssin vähentämiseksi.A combustion boiler comprising a flue gas duct and heat exchanger tubes in the flue gas duct (132, 212, 262) for heating or preheating liquid, steam or air. The combustion boiler comprises a first substantially planar sound attenuator plate (320) in the direction of flow of the flue gases, the first sound attenuator plate (320) comprising a sound absorbing material and said first sound attenuator plate (320) is located in said flue gas duct in the direction of flow of the flue gases after one of said heat exchanger tubes (132, 212, 262), whereby the sound attenuator plate attenuates noise caused by the turbulence of the flow of the flue gases. The sound attenuator plate (320) may be located immediately or almost immediately after the heat exchanger tube (132, 212, 262). In addition, the combustion boiler may comprise a vibration-preventing plate (600), which is a planar plate substantially parallel to the flow direction of the flue gases, and which vibration-preventing plate (600) is located in a direction perpendicular to the flow direction of the flue gases between two heat exchanger tubes (132, 212, 262) to reduce resonance in the heat exchanger area of the flue gas channel.
