II. Features of the DZL series boiler
1, the usage of high-performance heat transfer components - threaded pipe, with a reasonable gas flow rate, the boiler thermal efficiency is higher 6-8 percentage points than the state high professional standards.
2,arch tube plate, thread to make pot pipe from the quasi-rigid body shell variable based elastomer with the airfoil stack, completely avoid the defects that traditional high-temperature pyrotechnic tube boiler tube plate cracking.
3,reasonable and unique water circulation loop backwater ejector device (hot water boiler), improved the increased water velocity, to avoid the water-wall tube break.
4,the usage of inertial separation of dust furnace, supplemented by high-performance multi-collector, so that the concentration of dust emission boiler to meet the demand for a class.
5,reasonable structure of the boiler does not need a steel frame can support the weight of its own.     
6,the usage of energy, strong radiation furnace arch, can guarantee the stability of fuel combustion.
7,the usage of a high standard, high-quality auxiliary equipment, accessories and automatic control equipment, boiler guarantee security, stability operations, while reducing the labor intensity Boiler Operators.
8,the structure is compact , the boiler1-20t / h (0.7-14MW) can be single-layer arrangement.
