SZS series water tube boilers are used in pharmaceutical, food, daily chemical, tobacco, brewing, papermaking, steel, coking, electric power, colleges, hotels, public facilities and other industries and civil heating. Efficient water tube boiler is suitable for natural gas, city gas, liquefied petroleum gas, diesel oil, heavy oil and other fuels. The whole boiler adopts double cylinder longitudinal “D” type layout structure, the boiler is fully assembled, the layout is compact and reasonable, covers an area of small, the user site construction amount is small, can be completed in a short time installation.
The series of water tube boilers are equipped with flue gas condenser at the end of the boiler body, which reduces the flue gas temperature, improves the boiler efficiency, and reduces the harmful components in the flue gas. Boiler pressure body stress condition is good, drum and other important pressure components are not directly affected by high temperature flame radiation and erosion, pressure components telescopic, small thermal stress, to achieve a higher safety margin. SZS series boilers are divided into the whole body and economizer and other accessories, the body is composed of a furnace and a single loop convection heating surface, economizer is integrated transportation, to achieve the whole factory, to ensure the quality of the boiler. Small positive pressure combustion, small smoke wind resistance. The boiler smoke and air system is only equipped with blower, and the furnace is under micro positive pressure to reduce the air leakage of the boiler and improve the efficiency of the boiler.
The efficient water tube boiler body and the furnace are all surrounded by membrane water wall, so that the furnace wall can be reliably sealed to prevent flue gas leakage. At the same time, the use of light furnace wall, reliable operation, small heat loss, small thermal inertia, easy to realize fast start and stop. These are the models of SZS type water tube boiler and the overall composition of the boiler. For detailed quotation, you can consult online customer service or call +8618861589023 hotline.
The furnace of industrial water tube boiler is placed outside the cylinder body, and the volume of the furnace can be large or small, which can meet the requirements of combustion and increasing evaporation. The drum is generally not heated directly, and the pipe containing water vapor is placed in the furnace or flue as the heating surface, so that the heat transfer performance and safety performance are significantly improved. The boiler water preheating, steam and steam overheating in the heating surface economizer, water wall and convection tube bundle, superheater completed. At the same time, its water vapor system, combustion system and auxiliary system are more complex, but the structure of a single pressure bearing part of water tube boiler is relatively simple.
SZS series water tube boiler because water preheating, steam and steam overheating are completed in the pipe, pipe scaling is difficult to remove, so the water tube boiler has higher requirements for water quality, operation, management level is also higher requirements. The boiler adopts the design of large furnace, so that the flue gas stays in the furnace longer, the combustible gas is fully burned, and the combustion efficiency is improved. Furnace and flue are covered by membrane water wall, with large heating surface and less heat loss, which can realize quick start of boiler.
Efficient water tube boiler adopts compound circulation mode, safe and reliable operation. It is mainly reflected in the radiation heating surface of the furnace and the forced circulation in the high temperature area of the tube bundle, and the natural circulation in the low temperature area of the tube bundle, so that the water resistance is small and the resonance of the tube bundle is avoided. SZS series industrial boiler heating surface layout is flexible, choose medium flue gas flow rate, reduce flue gas resistance, low power consumption. Zozen Boilers series adopt world brand auxiliary machines and components such as burner and gas valve set, provide complete gas valve set and accessories including filter, pressure regulating valve, solenoid valve, etc., to ensure the safety of gas. At the same time, the boiler can always be in the best combustion state under operating conditions, achieving the double effects of energy saving and environmental protection.
