Ⅰ, structural characteristics and performance advantages
1.SZS series boilers adopt a double-barrel (or three-barrel) D-type film wall furnace structure. The boiler is composed of upper (middle), lower cylinder, film type water wall, convection heat exchange tube bundle, superheater, tail energy saver, condenser, etc.
2. The combustion chamber adopts full film water wall structure, good sealing, no air leakage, less heat dissipation, increase the boiler heating surface, improve thermal efficiency.
3. Full film wall structure, furnace and flue steel, strong anti-explosion ability, safe operation.
4. Convection tube bundle single stroke, reduce flue gas side resistance, economic flow rate design, micro positive pressure combustion, improve heat transfer efficiency.
5. With larger furnace volume, section width and length size, suitable for various burner arrangements. Convenient multi-burner arrangement. The fuel stays in the furnace for a long time, burns more fully, and is more efficient.
6. Large furnace size, meet the requirements of ultra-low nitrogen combustion, combined with the burner can make NOx emissions meet the environmental requirements of use.
7. The furnace water wall and convection heat exchange surface are arranged, the boiler heats up fast, the boiler water capacity is large, the operation is safe and stable.
8. The boiler adopts high-quality insulation materials and special construction technology, which has small heat loss and fuel saving.
9. Automatic burner, with ignition program control and overpressure, flameout, gas leakage protection automatic control system.
10. The boiler adopts mechatronics automatic control technology. Remote human-computer interaction and data sharing can be achieved through mobile Internet.
Ⅱ,Product range:

Others: Special design and manufacturing can be carried out according to various parameter requirements put forward by users. Provide product types that meet customer needs and customize products.
Ⅲ，Natural gas, LNG (liquefied natural gas) CNG (compressed natural gas), light oil, city gas, heavy oil, biogas;
It can also be designed according to the fuel type provided by customers.
The water quality standard of steam boiler when using chemical water treatment outside the furnace
Water quality requirements:GB/T1576 Water quality of industrial boilers
Note: Dissolved oxygen content: When the rated evaporation capacity of the boiler is ≥6t/h, it should be deoxygenated; when the rated evaporation capacity is < 6t/h, if local corrosion is found in the boiler, deoxygenation measures should be taken. The oxygen content of the boiler feed water for the steam turbine should be ≤0.05mg/L
Water quality standard for hot water boilers
Gas fired steam boiler（2-15t/h）
Gas fired steam boiler（20-50t/h）
