Easy maintenance and repair:

Boilers are equipped with removable smoke box doors at both the front and back. The back features observation and inspection holes, allowing access into the furnace for inspection and cleaning. Manholes are also provided on the boiler body, with the structural design carefully considering ease of future maintenance and repairs.

Product Introduction:

WNS fuel (gas) steam and hot water condensing boilers feature an external integrated finned tube economizer, a separate condenser, compact structure, and easy maintenance, with highly significant energy-saving effects. The thermal efficiency exceeds 100% based on the lower heating value of the fuel. To meet customer requirements, a combination of a programmable logic controller (PLC) with a touch screen and additional buttons can be installed to achieve a dual-path intelligent control system for manual and automatic operation. Interface预留 for remote control is available.

The WNS series fully automatic fuel (gas) steam boilers (novel utility patent) utilize a horizontal three-pass wet-back structure, improving the boiler operating environment and enhancing efficiency and lifespan; all flue gas channels are submerged in water, equipped with a surplus hot water tank and a complete insulation outer design. The smoke box is sealed with a labyrinth structure to prevent smoke leakage. The boiler thermal efficiency reaches over 85%, featuring a combination boiler pot with a good expansion wave pot and conical pot, where the pot size matches the flame, reducing the flue gas flow area in sequence to ensure uniform flow of flue gas, maintaining the heat exchange time for high-temperature flue gas in the boiler for optimal heat transfer. It employs a high-performance burner that perfectly matches the boiler, ensuring comprehensive automatic regulation for complete combustion, fuel saving, and pollution reduction. Ultra-fine glass wool with high insulation performance is used to minimize heat loss. An intelligent energy-saving control system is adopted to manage the boiler and steam (water) supply system, adjusting fuel supply according to different loads for enhanced energy efficiency. The installation method is an integral quick-install boiler, with minimal vibration and no special requirements for the foundation, eliminating the need for anchor bolts, making installation simple and straightforward. The movable boiler head structure allows for compatibility with various burners, easy replacement of the boiler head, and quick maintenance. The front and rear smoke boxes use a removable design, allowing for convenient internal inspection, maintenance, and care, featuring a simple and convenient design, innovative product design, reasonable structure, and good process performance, making this product stand out with superior quality.

Product Features:

The design, manufacturing, and supervision of the boiler strictly adhere to the "Regulations for Safety Supervision of Steam Boilers," JB/T 10094-2002 "General Technical Conditions for Industrial Boilers," and JB/T 1619-2002 "Technical Conditions for the Manufacturing of Shell Boilers," ensuring the long-term safe and stable operation of the boiler.

2. The body features a pot shell-type fully wet back downstream three-pass smoke tube structure, with flames burning micro-positive pressure within the large combustion chamber, fully extending, resulting in low combustion heat load and reduced NOx emissions.

3. Wave-shaped furnace liner and threaded smoke tube structure, which enhances strength while also catering to the thermal expansion requirements of all parts.

4. All main welds are joined by butt welding and have been inspected for non-destructive testing with X-rays and ultrasonic methods, ensuring the welding quality meets national standards.

5. The boiler has a large water volume and gas space, with strong load adaptation capability. The design of the internal equipment ensures that the steam moisture content is below 4%, meeting the higher quality requirements of the steam for the users.

6. Utilizes advanced thermal insulation materials, featuring lightweight, minimal heat loss, and excellent保温 performance.

7. The water level alarm uses stainless steel as the electrode rod and polytetrafluoroethylene as the insulating material. It is inserted from above, easy to clean, reliable in performance, and has a long service life.

8. The front and rear cigarette boxes are hinged for easy opening, facilitating quick maintenance and repair.

9. Oxygen Content Adjustment (Optional): This system successfully monitors the oxygen content in flue gas and transmits the data to the control system in real-time. Through intelligent analysis by the computer, it automatically adjusts the ratio of the combustion equipment, keeping it in optimal working condition, significantly enhancing combustion efficiency and thereby substantially reducing fuel consumption.

Protective System:

Boilers feature multiple safety protections: electrical leakage protection automatically cuts off power; overheat protection stops the burner and sounds an alarm when the boiler water temperature exceeds the alarm temperature; secondary overheat protection automatically cuts off the secondary circuit and stops the boiler when the outer shell temperature exceeds 105℃; dry burning protection uses a precise water level electrode rod to monitor water levels in real-time, stopping the boiler and preventing dry burning when the water level reaches or falls below the critically low level due to other reasons.

Application Fields:

Ironing, dry cleaning, drying, washing, spinning, pressing, and flat irons, etc., for matching equipment use.

2: Supply drinking water, steamed food, rice noodle production, soy milk boiling, tofu machine, steamed rice box, sterilization tank, labeling machine, filling machine
