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.
Capacity: 1t/h, 2 t/h, 4t/h, 6t/h, 8t/h, 10t/h, 12t/h, 15t/h, 20t/h, 25t/h, 30t/h, 35t/h, 40t/h, 44t/h and mor., Rated evaporated pressure: 1.25 MPa, 1.6MPa and more. Steam can be saturated steam and superheated steam, 1~6 t/h is peckage, 6~10 t/h is shop- assembled, 15~30 t/h half shop- assembled, 35~44 t/h is field assembled.
