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.
Energy-saving and environment-friendly: The adoption of advanced gasified burning tecnology, indluding the gasified spiral burning chamber and embedded device of second distribution of spiral turbulence, makes the burning of fuels more efficient.
Threaded flues, which are efficient in heat transmission, and reasonable flowing speed of smoke, push the thermal efficiency to 85% and higher. The adoption of biomass pellet fuel enables zero CO emission. With the density of discharged smoke lower than 50mg/m and blackness of exhaustion lower than Ringelmann level-1, all data has satisfied national environmental protection standard for type-1 areas.
Low operation cost: Biomass pellet is a new environment-friendly renewable fuel promoted by the government it features high heating value, low cost and easy accessibility. The operation cost of the boiler is only 1/4 of that electric boilers and is 1/2 lower of that oil gas boilers.
Highly automatic: The digital integrated controller enables users to set up auto control so as to control the burning. The operation is as simple as that for oil and gas boilers and it features automatic ignition, material-feeding and ash-clearing.
Safe: Quality auxiliary machines, accessories and auto-control equipment guarantee safe and stable operation.
