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.
1.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.
2.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.
3.The independent secondary fan makes it easy to control and adjust the wind volume and pressure.
1. Our uniquely customized system solutions deliver maximum energy efficiency and low emissions
2. State of the art computer, variable frequency and video monitoring systems are in place to ensure the safe operation of our boliers
3. Agreeable design of outer casings and a wide choice of colors to your order

The arch design of DZL chain grate coal-fired boiler adopts the latest scientific research achievement of "Xi'an Jiaotong University National Science and Technology Progress Second Prize". The rear arch is low and long, the exit section is anti-inclined, the front arch inclination angle is 45 degrees and the rear arch corresponds, forming an inverted "alpha" flame, which is conducive to the combustion of inferior coal, and the coal is adaptable.
