DZL Series Biomass Boiler Introduction
DZL series quick-load boiler is a horizontal three-return water and fire pipe chain grate boiler. The boiler body is arranged in a longitudinal direction of a single drum, and a threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water wall on both sides constitute a furnace heating surface. The burning equipment adopts a light chain grate. Electrical control realizes stepless speed regulation of the grate, limit parameter alarm and interlock protection.
DZL Series Steam Boiler Advantage
- DZL series steam boiler is a single boiler tube vertical layout horizontal water-fire tube fast installed chain grate boiler. Compact structure, small floor space, short installation cycle, low cost, low investment.
- Adopt multiple interlock protection device to ensure safe and reliable operation of boiler.
- This series of biomass fired boiler low exhaust temperature and high thermal efficiency.
- It can match various kinds of dust removal equipment and can meet the environmental protection requirements of different countries.
- Good combustion conditions, full combustion, and wide adaptability to fuel, can adapt to a variety of biomass fuels.
DZL Series Boiler Manufacturing Process Features
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, threaded pipe pressing and convection tube processing are all adopted advanced CNC process.
- Firstly adopt arch tube plate and threaded fire tube structure at home to increase heat conduction to solve the problem of rear tube plate cracked.
- The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.
Boiler Welding Process
- The biomass steam 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% rediographic inspection.
- The weld of smoke tube and tube plate will be pre-expanded first to remove the gap between tube and tube plate. And then adopt argon arc automatic welding process. This may relief stress efficiently and extend the DZL series biomass boiler working life.
- Tube flange weld adopts robot welding.
- Chain grate are all manufactured by ZOZEN and be test running for 72 hours before leaving the factory to make sure that the degree of tightness is moderate.
