WNS Gas-Fired Hot Water Boilers Features:

1. Rational Design: Horizontal internal combustion triple-acting full-wet back design, 100% corrugated furnace tube, with excellent thermal expansion properties. The water包围fire overall design, with ample heating surface area and reasonable structural arrangement, ensures the high efficiency operation of the boiler.

2. Manufacturing Standards: The company has established a comprehensive quality assurance system that operates reliably, with the manufacturing process strictly controlled and supervised by a special inspection agency on-site.

3. High Efficiency & Energy-Saving: The steam and hot water boiler series boast a thermal efficiency of 87%-92%. The large combustion chamber combined with reasonable structural arrangement allows for more heat to be transferred into the water, significantly enhancing the heat exchange capacity between fuel-steam and fuel-hot water.

4. Meets Environmental Standards: Large combustion space, maximizes radiant heat exchange, and features a high-quality, reliable imported burner, ensuring complete combustion of fuel and significantly reducing harmful emissions in flue gases. Our company's fuel (gas) steam and hot water boilers have passed legal department testing and meet national environmental protection standards, making them ideal eco-friendly products.

5. Fully Automatic Operation: Users simply press the start button, and the boiler operates according to the set program. Load regulation and water supply are all fully automatic, requiring no constant supervision.

6. Long Service Life: The professional design of our boiler products, advanced production technology, and superior boiler-specific steel ensure that the lifespan of the boiler body is over 15 years.

7. Easy Maintenance and Repair: The boiler is equipped with removable smoke box doors at both front and back, featuring observation and inspection holes at the rear for easy access to the furnace chamber for cleaning. The boiler body has a manhole for convenient maintenance, with the structural design taking future repairs into account.

Structure of Gas Boiler

Burner

The construction of the gas burner consists of the following 5 systems:

1. Air Supply System. The function of the air supply system is to deliver air of a specific speed and volume into the combustion chamber. Its main components include: housing, fan motor, fan impeller, air gun flame tube, air door controller, air door baffle, cam adjustment mechanism, and diffuser disc.

2. Ignition System. The function of the ignition system is to ignite the mixture of air and fuel, with its main components including: ignition transformer, ignition electrode, and high-voltage electrical cable. A safer type of ignition system is the electronic pulse igniter, widely used by manufacturers like Zuyi Energy-saving Gas Boilers. It's convenient and time-saving, requiring only a finger press to operate, and boasts high safety, preventing accidents caused by accidental extinguishing. In case of a flameout, the control system can promptly close the solenoid valve to cut off the gas supply.

3. Monitoring System: Ensures safe and stable operation of the burner, with key components including flame sensors, pressure sensors, and temperature sensors, etc.

4. Fuel System. The function of the fuel system is to ensure the fuel required for the burner's combustion. The main components of a fuel oil burner's fuel system include: fuel lines and connectors, fuel pumps, solenoid valves, nozzles, heavy oil preheaters. For gas burners, the main components are: filters, regulators, solenoid valve groups, ignition solenoid groups, and fuel butterfly valves.

5. Electrical Control System. The electrical control system serves as the command and coordination center for the aforementioned systems, primarily controlled by programmable controllers. Different programmable controllers are used for different burners, with common types including: LFL series, LAL series, LOA series, LGB series. The main difference lies in the varying duration of each program step. [1]

Controller

1. Super-large full Chinese LCD display, with built-in incandescent night light, ensuring clear visibility of the screen content day or night.

2. The image animation displays the water level, heating, pump valve, and alarm status, making the boiler operation clear at a glance.

3. CPU Intelligent Central Processing Unit, all programs integrated on a single digital chip, with strong expandability, high level of automation, easy operation, and powerful functions.

4. Equipped with various control functions including time setting, temperature setting, pump valve setting, continuous setting, timer setting, and pressure setting, allowing for any work state to be set at will.

5. Equipped with low water level alarms (anti-dry burn feature), high water temperature alarms, and high pressure alarms, as well as multiple alarm functions and interlock protection capabilities (shutdown), to eliminate potential safety hazards.

6. Detailed self-diagnosis, record-keeping, and easy maintenance checks.
