Product Details

Fuel-gas boilers are widely used in institutions and enterprises such as schools, textile factories, garment factories, large supermarkets, clothing factories, dyeing and printing factories, hotels and inns, canteens, restaurants, food factories, beverage factories, bean product factories, meat product factories, canning factories, breweries, packaging factories, building material factories, paint factories, and swimming centers.

Operating Principle:

1. Three-pass structure: Utilizing the internationally popular shell-type three-pass, full-wet-back design, with a large combustion chamber for more complete combustion. Fuel burns under micro-positive pressure within the furnace, with the high-temperature flue gas turning 180° through the regenerative chamber and entering the flue pipe bundle. After passing through the pressure front smoke box, it turns another 180° into the second bundle and is discharged into the atmosphere after convective heat exchange.

2. Wavy Furnace Tube: The combustion chamber features a full wavy furnace tube structure, which not only strengthens the disturbance of flue gas but also increases the radiant heat transfer area; it enhances the rigidity of the furnace tube while effectively reducing its expansion stress; it improves the heat transfer efficiency and promotes the combustion of fuel inside the furnace.

3. Unique welding technique for chimney and tube plate: Utilizing an advanced process of pre-expansion followed by full welding and then re-expansion, it effectively prevents tube gap corrosion and enhances welding strength; Employing threaded chimneys with high thermal conductivity to intensify convective heat transfer, reduce exhaust gas temperature, and improve the boiler's thermal efficiency.

4. Symmetrical swinging hinge on front and rear smoke doors: Easy to open, convenient for maintenance and cleaning.

5. The boiler features a wet-back structure with fully beveled butt joints, offering high reliability and low maintenance costs.

6. The design of the rear-view device facilitates observation of the combustion condition.

7. Equipped with multiple protective functions such as over-temperature, over-pressure, water shortage, leak detection, and fire extinguishing, the boiler operates safely and reliably.

Performance Advantages

1. Scientific design, rational structure --- The boiler body employs a wet-back three-pass design, full corrugated furnace tube, and threaded flue tube structure, offering excellent thermal expansion properties; the tube plate and cylinder are connected using a plate edge joint structure, with the main welds of the body being in a butt joint configuration, all焊接 using submerged arc automatic welding.

2. Equipped with comprehensive processing equipment and advanced production techniques -- The company boasts an internationally advanced large-scale steel structure production facility with good natural lighting and rational layout. The production equipment is well-matched and complete, with over 1,100 units of various equipment, including multiple sets of 400KVA and other non-destructive testing devices. The product manufacturing employs advanced numerical control cutting, milling, submerged arc automatic welding, argon arc welding, and smoke tube plate welding, ensuring product quality.

3. High level of automation; reliable equipment operation - utilizing a combination of mechatronic control equipment and programmable logic controllers (PLCs). The advanced PLC serves as the "central processing unit" of the control system. The control system is operated via a touchscreen, significantly enhancing the automation and reliability of the boiler operations, making the operation simpler and more intuitive.

4. Long lifespan, powerful output, high efficiency —— Our scientific product design, advanced processing technology, and stringent quality control ensure that all our boiler equipment has a continuous operation lifespan of over 10 years. The boiler's radiant heating surface features a full wave furnace, while the convective heating surface uses threaded flue pipes, boasting a large heating surface. This results in a sufficient heat output and an energy efficiency of over 92%, exceeding national standards.

5. Abundant fuel supply, energy-saving and environmentally friendly -- The boiler combustion chamber is designed reasonably, fully adaptable to various fuels such as city gas, natural gas, light diesel oil, and heavy oil. Fuel burns micro-positively within the furnace, ensuring complete combustion with minimal smoke pollutants. The technical indicators such as smoke opacity, dust opacity, concentration, and noise of the boiler all exceed the national first-class area standards.

6. Matching spare parts, international brands - Burners are from German Weishu, Finnish Oyly, Italian Liao, German Baide, and other international brands. The key valves and instruments are matched with domestic brands and internationally renowned brands, such as German Siemens, French Schneider, and Japanese Omron, ensuring the safe operation of the boiler.
