New SZS Series Gas Steam Boiler

The new SZS series gas steam boiler is a new type of gas boiler jointly developed by our company and Xi'an Jiaotong University. Based on the mature technology of domestic SZS gas boilers, this boiler model adopts the national invention patent of Xi'an Jiaotong University - the optimal design software for oil and gas boilers. Its structural performance is at the domestic leading level. This type of boiler adopts an electromechanical integrated structure, featuring a generous appearance, compact structure, less space occupation, convenient transportation, and less infrastructure investment. It not only follows the concept of energy conservation and environmental protection but also meets the thermal energy required for engineering projects. In production and use, this type of boiler truly achieves clean combustion, pollution-free emissions, convenient operation, and sufficient output.

◆Product Introduction:

The SZS series oil and gas boiler is a double-drum longitudinal "D" type layout fast-assembly water tube boiler. It consists of upper and lower drums, membrane water walls, convection tube bundles, and a flue gas condensation recovery device. After the fuel is burned in the furnace, the flue gas is discharged into the chimney through the convection tube bundles and the flue gas condensation recovery device. This type of boiler achieves the advantages of sufficient combustion, pollution-free emissions, convenient operation, and easy installation. The boiler has high thermal efficiency, high output, strong load adaptability, high degree of automation, convenient operation, safe and reliable operation. It is an ideal green environmental protection product with high efficiency, low consumption, and low pollution. Coupled with the implementation of the national coal-fired boiler reform policy, this series of boilers will play a very important role in the field of thermal equipment applications in the future.

◆Product Usage:

Widely used in hospitals, schools, textile factories, clothing factories, large supermarkets, clothing factories, printing and dyeing factories, hotels, canteens, restaurants, food factories, beverage factories, bean product factories, meat product factories, canning factories, wineries, pharmaceutical factories, packaging factories, building material factories, paint factories, swimming pools and other enterprises and institutions.

◆Product Advantages:

1. Adopting a double-drum "D" type layout, the structure is compact, occupies a small area, and has good flame filling.

2. The furnace adopts a membrane water wall structure, and the boiler adopts a fully enclosed welded structure with an airtight inner protective plate, providing good furnace wall sealing.

3. The boiler is equipped with a large heating surface area, and there is enough steam and water space to ensure stable boiler parameters.

4. The tail is equipped with a flue gas condensation recovery device, which can effectively control the exhaust gas temperature and improve boiler thermal efficiency.

5. High thermal resistance material is used as the thermal insulation layer, and the insulation performance is good. The outer layer of the boiler adopts a pressed protective plate, which is beautiful and attractive.

6. Adopting a fast assembly structure, the entire boiler is designed on a strong base, making installation and transportation convenient.

7. The furnace is equipped with inspection holes, providing great convenience for use and maintenance. There is an explosion-proof door on the top of the furnace.

8. Adopting fully automatic burner, continuous electric adjustment is adopted for water supply, and the combustion efficiency is high. It also has multiple protection functions and operates safely and reliably.

◆Product Structure:

1. Three-pass structure: Adopting the internationally popular three-pass, fully wet back structure of the boiler shell, and the large-volume design of the combustion chamber, the combustion is more sufficient. The fuel is burned under slight positive pressure in the furnace, and the high-temperature flue gas passes through the furnace and turns 180° into the first flue tube bundle through the return chamber, then turns 180° into the second tube bundle through the oppressive front smoke box, and is discharged into the atmosphere after convective heat exchange.

2. Corrugated furnace: The combustion chamber adopts a full corrugated furnace structure, which not only strengthens the disturbance of the flue gas but also increases the radiation heat transfer area; it not only increases the rigidity of the furnace but also effectively reduces the expansion stress of the furnace; it not only enhances the heat transfer effect but also promotes the combustion of fuel in the furnace.

3. Unique welding process between smoke pipes and tube plates: Adopting the advanced process of pre-expansion, full welding, and then expansion, which not only prevents crevice corrosion between pipes but also enhances welding strength; adopting threaded smoke pipes with high heat transfer coefficient to strengthen convective heat transfer effect, reduce exhaust gas temperature and improve the thermal efficiency of the boiler.

4. Symmetrical hinged front and rear smoke doors: easy to open, convenient for maintenance and cleaning.
