Unique Orientation
The first choice of package boiler
SZL series products have adopted double-drum offset hearth(D type layout),Water-cooled arch and smoke three-pass process design. Back shack pipe and water-cooled arch form an independent cyclone reburning chamber, all for water tubes structure, fast pressurizing,high quality steam by adopting the new steam-water separator equipment. the ready-packaged boiler makes it convenient to install and transport. SZL series products are key recommendation products for China's energy conservation projects, which obtain the national scientific and technological process second prize and Singapore new product expo golden lion award.
