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.It is the rational design of arch inside the furnace that improves combustion condition, enhances the dust falling function in it and reduces the pollutant emission of the boiler.
2.With good sealing, the wind box is easily to operate and can provide rational wind. Consequently, it reduces the air excess coefficient and increases the boiler thermal efficiency.
3.With compact structure, smaller boundary dimension than other same volume boilers, it can save the investment of capital construction for the boiler room.
