Product introduction

  DZL series package boiler is a horizontal three-pass water and fire pipe chain grate boiler, which uses medium-sized bituminous coal. The boiler body is vertical single drum, and the threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water walls on both sides constitute a radiation heating surface of the furnace. The combustion equipment uses light chain grate, the whole package is finished in the factory. The electric control makes the governor stepless speed regulation, the limit parameter alarm and the interlock protection.

CNC manufacturing technology:

  The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced numerical control processing to reduce the assembly stress and prolong the service life of the boiler.

  Steel pipe cutting, thread pipe pressing and convection pipe processing all adopt advanced numerical control technology.

  The use of 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 rear tube sheet.

  The layout of chain grate is neat and beautiful, result in front and rear smoke box panel using CNC plasma cutting machine.

Advanced welding process

  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 are subjected to 100% ray detection.

  The welding of smoke pipe and the tube plate adopts pre-expansion to eliminate the gap between the tube and tube plate, then be welded by automatic argon arc. 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 go wrong.

Precision parts processing

  Advanced manufacturing technology, using assembly line automatic spinning operation.

  Enhance heat transfer and raise boiler thermal efficiency.

  Threaded fire pipes are highly efficient heat transfer elements for many years of research by our company. After continuous optimization, the heat transfer coefficient is 1.8 times higher than that of conventional fire pipes when the selection of thread groove depth and pitch.

Unique structural design

  Disturbed flue gas to ensure complete combustion of volatiles.

  The air volume accounts for about 30% of the total, and the wind speed is about 50m³.

  The independent secondary draft fan makes it easy to control and adjust the wind volume and pressure.

  The high-temperature smoke generated by the combustion first enters the eight-character flue on both sides of the body from the tail (in this case, the water pipe type), and the flue gas flows outside the pipe.

  The flue gas cooled by the eight-character flue then enters the threaded tube (in this case the fire tube type) arranged in the drum from the front smoke box.

  The flue gas will be exhausted from the rear smoke box finally, this design fundamentally solves the problem of cracking of the tube sheet of a pure fire tube boiler.

Abundant auxiliary configuration

  Sow feeder: sow feeder feed fuel equally to avoid flashback

  Speed control gear: design reasonable rotating speed according to the combustion speed of biomass to make sure the fuel burning out.

  Panels: cold-rolled embossed and concave-convex panels, strong and elegant.

  Inspection door: reasonable manhole and hand hole layout, easy to maintenance. Furnaces are equipped with access doors for easy access and maintenance.
