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. Its main components include: ignition transformer, ignition electrode, and high-voltage electrical cable. A safer type of ignition system is the electronic pulse igniter, widely used by manufacturers such as Zhuoyi Energy-Saving Gas Boilers. It is convenient and time-saving, requiring only a finger press, 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 path in case of flameout.
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 primarily have 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 communication center for the aforementioned systems, primarily controlled by programmable controllers. Different programmable controllers are equipped for various burners, with common types including the LFL series, LAL series, LOA series, and LGB series. The main difference lies in the varying time intervals of the program steps. [1]
Controller
1. Full-size Chinese LCD screen with built-in incandescent night light, ensuring clear visibility of screen content day or night.
2. The image animation displays the water level, heating, pump valve, and alarm status, making the boiler's operation clear at a glance.
3. CPU intelligent central processor, 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 desired operational state to be set.
5. Equipped with low water level alarms (anti-dry burning feature), high water temperature alarms, high pressure alarms, and various alarm functions with interlock protection capabilities (shutdown), to eliminate potential safety hazards.
6. Detailed self-diagnosis, record-keeping, and easy maintenance checks.
Well-designed
Horizontal internal combustion triple-reciprocating full-wet-back design with 100% corrugated furnace tube. Excellent thermal expansion properties. The water包围fire overall design, ample heating surface area, and reasonable structural arrangement ensure high boiler efficiency.
High Efficiency Energy Saving: The steam and hot water boiler series has a thermal efficiency of 90%-95%. The large combustion chamber, combined with a reasonable structural arrangement, allows for more heat to be transferred into the water, greatly enhancing the heat exchange capabilities between fuel and steam, and fuel and hot water.
Meets Environmental Standards: Large combustion chamber for maximum radiant heating efficiency, complemented by high-quality and reliable imported burners, ensuring complete combustion of fuel and significantly reducing harmful emissions in flue gases. Our fuel (gas) steam and hot water boilers have been tested and certified by authorized departments to comply with national environmental standards, making them ideal eco-friendly products.
Superior 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 and stable operation of the boiler.
Fully Automatic Operation: With just a push of the start button, the boiler operates according to the set program. Load reduction and water supply are all fully automatic, requiring no constant supervision.
Easy maintenance: The boiler is equipped with movable ash box doors at both front and back, with observation and inspection holes at the rear, allowing for easy access into the furnace for inspection and cleaning. Manholes are provided on the boiler body, with the structural design thoroughly considering ease of future maintenance and repairs.
