Aqua tube aquatubular boiler for burning sugarcane bagasse with a high efficiency. Compact structure and easy installation ensure efficient, clean, economic, safe and stable boiler operation, so it is widely used as an energy-saving and environment-friendly equipment in industry.Biomass Hot water boilers are the perfect sustainable solution for space and process heating in a wide range of industrial and commercial applications including process steam.
New type DZL(H) hot water boiler is the single drum longitudinal type water and fire tube shell water boiler,the burning equipment is the moving grate.The furnace wall take heat resistance as the whole trumpet bell and ramming to be the new process,the boiler host outside is the solid figure guard board shell.
This hot water boiler adopt chain grate,suitable for molding pellet fuel,can add a small amount of wood,wood block,also can burn with coal.
Feeding System Introduction:
1.Conveyor feeding mode (For biomass particles)
2.Elevating automatic feeding (For coal)
3.Blast feeding (For size of less than 50mm of small sawdust, or rice husk)
4.Screw feeder
