Introduction

DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace.

Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.

Benefits

Benefits
  • The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
  • Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
  • Arched tube sheets and threaded fire tube was first adopted in China to increase heat transfer and completely solve the problem of cracking of the back tube sheet.
  • Chain grate plate and back smoke chamber plate is cut by CNC plasma cutting machine, which looks neat and beautiful.
  • Construction

    Construction
  • The vertical and circumferential seam welding of the boiler adopts advanced automatic submerged arc welding technology to ensure the welding quality. All vertical and circumferential welds will go through 100% ray detection.
  • The welding of smoke tube and the tube plate adopts pre-expansion to eliminate the gap between the tube and tube plate, then be welded by automatic argon arc welding, which effectively eliminate stress and prolong boiler life.
  • The flange of the socket is welded by robots.
  • The chain grate is manufactured by our factory, and it is tested for 72 hours before leaving the factory to ensure that the tightness is moderate and won’t deviate.
