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.

Boiler design advantages
1. Adopting automatic screw feeding, with reasonable second air technology and half gasification structure
helping fuel combust completely, the thermal efficiency can reach more than 90%. Stable flame, producing
steam cautiously.
2. Primordial dust emissions density is low:The volume of the coal biomass-fired steam boiler is large and there is a dust
separation device, so the primordial dust emissions density will be controlled much lower than the standard allowed.
3. Control system: Installing microcomputer to operate with one-button, people just set the process, and it can
work automatically during the operating time. Once any abnormal situation to happen, stopping automatically
with sound-light alarm, and pointing to the failure code, so it saves time to maintain.
4. Our protected device is safe and reliable. Selecting superior pressure controller, safety valve, low water alarm,
overpressure alarm, over-temperature alarm, in order to make boilers operate safely.
5. Heating fast:There are many spiral gas tubes in the boiler and almost half of the coal fired steam boiler shell
can be heated, so the temperature can up soon.
6. It is simple to clean slag only after burning completing.
