WNS Gas-Fired Hot Water Boilers Features:
1. Rational Design: Horizontal internal combustion triple-return full-wet-back design, with 100% corrugated furnace tube, boasting excellent thermal expansion properties. The water包围fire overall design ensures ample heating surface area and reasonable structural arrangement, guaranteeing 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 fully controlled and supervised by a special inspection agency on-site.
3. 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 reasonable structural arrangement, more heat can be transferred into the water, greatly enhancing the heat exchange capability between fuel and steam, and fuel and 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 gas. Legally tested and verified, our oil (gas) steam and hot water boilers meet national environmental protection requirements, making them ideal eco-friendly products.
5. Fully Automatic Operation: Simply press the start button, and the boiler will operate according to the set program. Load regulation, water supply, and other functions are all fully automated, requiring no constant supervision.
6. Long Service Life: The professional design of our boiler products, advanced production technology, and high-quality boiler-specific steel ensure that the lifespan of the boiler body is over 15 years.
7. Easy Maintenance: The boiler is equipped with movable smoke box doors at both front and back, featuring observation and inspection holes at the rear, allowing for easy access to the furnace chamber for inspection and cleaning. Human access holes are also provided on the boiler body, with the structural design carefully considering future maintenance and repairs.
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 damper, 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 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 Zhuoyi Energy-Saving Gas 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 pathway in case of flameout.
3. Monitoring System: Ensures the safe and stable operation of the burner, with key components including flame monitor, pressure gauge, and temperature sensor.
4. Fuel System. The function of the fuel system is to ensure the fuel required for the burner to burn. The main components of a fuel oil burner's fuel system include: fuel pipes and connectors, fuel 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, with the main control components being programmable controllers. Different programmable controllers are paired with various burners, with common types including the LFL series, LAL series, LOA series, and LGB series. The primary distinction among them lies in the varying durations of the program steps.
