Features of WNS series steam boilers:

Design: Horizontal internal combustion triple-pass full-wet-back design, 100% corrugated furnace tube, with excellent thermal expansion properties. The water jacketed fire tube design ensures ample heating surface area and rational structural arrangement, guaranteeing the high efficiency operation of the boiler. Manufacturing Standards: The company has established a comprehensive quality assurance system that operates reliably, with the manufacturing process fully controlled and supervised by a special inspection agency. High Efficiency and Energy Saving: The steam and hot water boiler series have a thermal efficiency of 87%-92%, with a large combustion chamber and rational structural arrangement, which allows more heat to be transferred into the water, significantly enhancing the heat exchange capacity between fuel and steam, and fuel and hot water. Environmental Compliance: The large combustion space fully utilizes radiant heat transfer, combined with high-quality and reliable imported burners, ensuring complete combustion of the fuel and greatly reducing the emission of harmful components in the flue gas. The company's fuel (gas) steam and hot water boilers meet national environmental protection requirements and are ideal eco-friendly products. High Heating Quality: The steam boiler has ample steam storage space, ensuring the production of high-quality dry steam even under large load fluctuations. Excellent Configuration: Equipped with world-renowned burners, advanced control systems (main components are imported), valves, and pumps all using national quality products. The excellent boiler accessory configuration provides a strong guarantee for the safe operation of the boiler. Automatic Operation: The user only needs to press the start button, and the boiler will operate according to the set program. Load regulation, water supply, and other operations are all fully automatic, requiring no constant supervision. Long Service Life: The professional design of the boiler products, advanced production technology, and high-quality boiler-specific steel ensure that the boiler body has a service life of more than 15 years. Easy Maintenance: The boiler is equipped with removable smoke box doors at the front and back, with observation and inspection ports at the rear, allowing for easy access to the furnace for inspection and cleaning. The human access door is also designed with future maintenance in mind.

Structure of Gas Boilers

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 certain wind 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 disk.

2. Ignition System. The function of the ignition system is to ignite the mixture of air and fuel, with main components including: ignition transformer, ignition electrode, and high-voltage ignition cable. A relatively safe type of ignition system is the electronic pulse igniter, widely used by manufacturers like Zhuoyi Energy-Saving for gas boilers. It is convenient and time-saving, requiring only a finger press to operate, and boasts high safety. It prevents accidents caused by accidental extinguishing, as the control system can promptly close the solenoid valve and shut off the gas supply in case of a flame-out.

3. Monitoring System. Its function is to ensure the safe and stable operation of the burner, with main components including flame monitor, pressure monitor, temperature monitor, etc.

4. Fuel System. The function of the fuel system is to ensure the fuel required for the burner's combustion. The fuel system of oil burners mainly includes: fuel pipes and connectors, fuel pumps, solenoid valves, nozzles, heavy oil preheaters. Gas burners mainly have filters, regulators, solenoid valve groups, ignition solenoid valve 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 designed for different burners, with common types including the LFL series, LAL series, LOA series, and LGB series. The main difference among them lies in the varying time sequences of their program steps. [1]

Controller

1. Extra-large full Chinese LCD display, featuring an integrated incandescent night light, ensuring clear visibility of the screen content at any time, 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 are concentrated 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 desired operational state.

5. Equipped with low water level alarm (anti-dry burning function), high water temperature alarm, high pressure alarm, and various alarm functions with interlock protection capabilities (shutdown), to eliminate potential safety hazards.

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