Unique Orientation
The first choice of packaged boiler
SZL series product is a double-drum water tube assembly chain belt type grate boiler(A type layout).The boiler body has an upper drum and a lower drum lengthways arranged along the boiler center.The front of the upper drum and water wall tubes on two sides form a hearth surface,and the convection tubes between the rear of the upper drum and the lower drum form a convection heating surface.The economizer is arranged on the rear of the boiler,and high temperature smoke generated by burning was sucked partial heat in the hearth,enters the convection heating surface for heat transfer through the cooling room and is sent into the chimney by the include fan through the economizer and dust collector and discharge into the atmosphere. It is water tube boiler,three passes design,mature and advanced technology. It is well recognized by users.
