Unique Orientation
The first choice of sup-high cost performance boilerr
SZH series products have adopted double-drum offset hearth (D type layout),smoke three-pass process design, design of front-back arch and blank space in the middle segment to force smoke updraft .double furnace doors to achieve feeding coal from two sides. all water tubes structure, fast pressurizing,high quality steam by adopting the new steam-water separated equipment. the package boiler is easy install and transport. DZH series products are key recommendation products of China's energy conservation projects, which won the national scientific and technological process second class prize in our country and a golden lion award of new product expo in Singapore.
