There are two models of Bulk corner tube Hot Water Boiler, DHL and SHL. DHL series bulk boiler is the single-cylinder, 

horizontal, water-tube bulk boiler. And SHL series bulk boiler is 

 double-cylinder, horizontal, water-tube bulk boiler.  Boiler consists of upper cylinder, water screen, convection tube bank, 

steel-pipe coal economizer, tubular air pre-heater and other parts.  Water screen constructs the hearth at the front section 

of boiler.  Front and rear water screens 

form the front and rear water-cooled vaults.  There is convection tube bank in the horizontal flue pipe.  Steel-pipe coal 

economizer and tubular air pre-heater are laid at the tail of boiler.  Combustion unit adopts the scaled coal-leakage 

prevention grate. Ventilation mechanism in distribution chambers could be adjusted sensitively. Grate is driven by stepless 

variable gearbox.  Boiler is delivered in bulk and assembled on site.
