Features of WNS series steam boilers:

Design Reasonable: Horizontal internal combustion triple-pass full wet-back design, with 100% wave-shaped furnace shell, featuring good thermal expansion and contraction properties. The water-enclosed fire design ensures ample heating surface area and rational structural layout, guaranteeing the high efficiency operation of the boiler. Manufacturing Standard: The company has established a comprehensive quality assurance system that operates reliably, with the entire product manufacturing process strictly controlled and supervised by a special inspection agency. High Efficiency and Energy Saving: The steam and hot water boiler series have thermal efficiencies ranging from 87% to 92%, with a large combustion chamber and rational structural arrangement, allowing more heat to be transferred into the water, greatly enhancing the heat exchange capacity between fuel and steam, and fuel and hot water. Environmental Compliance: With a large combustion space, full utilization of radiant heat transfer, and the use of high-quality and reliable imported burners, fuel is fully combusted, significantly reducing the emission of harmful components in flue gas. According to testing by authorized departments, our fuel (gas) steam and hot water boilers meet national environmental protection standards and are ideal eco-friendly products. High Heating Quality: Steam boilers have ample steam storage space, ensuring the production of high-quality dry steam even under significant load fluctuations. Excellent Configuration: Equipped with world-renowned burners, advanced control systems (main components are imported), valves, and pumps all use national high-quality products. The excellent boiler accessory configuration provides a strong guarantee for the safe operation of the boiler. Fully 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专人 supervision. Long Service Life: The professional design, advanced production technology, and high-quality boiler-specific steel ensure that the life of the boiler body is over 15 years. Easy Maintenance: The boiler is equipped with movable smoke box doors at the front and back, with observation and inspection holes at the rear, allowing for easy access to the furnace for inspection and cleaning. A manhole is also provided on the boiler body, with the structural design taking future maintenance into consideration.

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 with a specific 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 disc.

2. Ignition System. The function of the ignition system is to ignite the air-fuel mixture, with its main components including: ignition transformer, ignition electrode, and high-voltage ignition cable. A safer type of ignition system is the electronic pulse igniter, widely used by manufacturers like Zhuoyi Energy-saving Boilers. It is convenient and time-saving, requiring only a finger press to operate, and offers 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 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 fuel system of oil burners mainly includes: oil pipes and connectors, oil pumps, solenoid valves, nozzles, heavy oil preheaters. For gas burners, the main components are: filters, regulators, solenoid valve groups, ignition solenoid valve groups, and fuel butterfly valves.

5. Electric Control System. The electric control system serves as the command and coordination center for the aforementioned systems, primarily controlled by programmable controllers. Different programmable controllers are matched with different burners, with common types including the LFL series, LAL series, LOA series, and LGB series. The main difference lies in the varying durations of the program steps.
