Home / Product /SHL (Horizontal double drums chain grate) Double Drums Bulk Chain Grate Steam Boiler

  SHL series of boiler is the bulk industrial boiler with dual boiler cylinders and transverse arranged,as well as the natural cycling coal combustion water pipe boiler. The transverse upper and lower boiler cylinders and water cooling pipe walls together form the silo type furnace,together with convection pipe bundle and collection chest to form the boiler body frame. At the rear part,there is a coal saver air pre-heater:and if necessary,it isavailable to set up superheater inner furnace.The combustion equipment is squama grating,free timing control.Exit shop in bulk type for site assembly and construction. The smog flow is a type of multi-backhaul.

  This type of boiler has the following characteristics: capable of over duty.quick in temperature rise,high in heat efficiency,less land keeping leak-free squama grating makes greatly enhauced reliability in performance suitable for extensive varieties of coal furnace arch and wall can be built incasting way,good in block out performance .which betters ignition conditions, environment protective and energy saving, fierce combustion,high extent inautomation,stable in performance sate and reliable,together with very long working life.

  This type of boiler features are in sufficient output and high efficiency.Excellent adaptability for varieties of coal,safe and reliable,good in dusterand de- smog and etc. It is extensively applied in field of public living heating.

01

Boiler manufacturing process
  • Key processing technology like material preparation and circling of steel plate , drilling of drum and tube plate , etc are all adopted advanced CNC machining process to decrease the assemble stress and extend the boiler working life.
  • Steel tube cutting and convection tube processing are a adopted advanced CNC process.
  • Boiler manufacturing process

    02

    Boiler welding process
  • The boiler vertical and circular seam adopts advanced unionmelt welding process to ensure the welding quality . All the vertical and circular seams will be done 100% radiographic inspection.
  • Tube flange weld adopts robot welding.
  • The chain grate panel , front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.
  • Boiler welding process

    03

    Water circulation
  • Boiler water circulation adopts natural circulation . Each heating area has independent downcomer for water supply to make sure the whole water circulation is safe.
  • Water circulation

    04

    Large furnace design
  • Make flue gas stay longer in furnace and make ash and combustible gas firing sufficiently to improve boiler heat efficiency.
  • Decrease the flue gas rising speed in furnace to reduce the ash quantity and decrease boiler original emission concentration.
  • Large furnace design

    05

    Overhaul platforn
  • Platform and ladder adopt grating plate to ensure the strength and rigidity of platform ladder.
  • Reasonable arrangement ensure all the operation and maintenance site are easy to reach.
  • Overhaul platforn
