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.Threaded smoke tubes are highly efficient heat transfer elements which is from many years research of our company. After continuous optimization, the heat transfer coefficient is 1.8 times higher than normal smoke tubes.
4.The high-temperature smoke generated by the combustion first enters the horoscope flue on both sides of the body from the tail (in this case, the boiler is water tube type), and the flue gas flows outside the tube.
our DZL series coal-fired steam boiler has been exported to over 90 countries, such as Pakistan, Egypt, Indonesia, Malaysia, Ethiopia, Nigeria, South Africa, etc.

The burning equipment is a quick-loading grate, and the burning equipment is manufactured and installed in the factory, and can be directly installed on the foundation after being transported to the construction site. The structure is reasonable and compact, and the steel consumption is low, so that the performance, weight and structure size of the boiler are obviously advanced compared with domestic products of the same capacity.
01
02
The rear arch is low and long, so it is well burning. The two wing flue and side wall bricks are fired with refractory bricks.
03
Because the high temperature flue gas first enters the settling chamber, and then enters the two wings flue and the front smoke box from both sides, the smoke and dust removal effect is good.
04
The structure of pressure parts is reasonable, and it can run safely under the condition of ensuring water quality.
