The main components of gas boilers are gas burners and boiler controllers.
1. gas burner
The gas burner structure is composed of the following 5 systems:
1. Air supply system The function of the air supply system is to send air with wind speed and air volume into the combustion chamber. Its main components are: shell, fan motor, fan impeller, air gun fire tube, air door controller, air door baffle, Cam adjustment mechanism, diffuser.
2. Ignition system The function of the ignition system is to ignite the mixture of air and fuel. Its main components are: ignition transformer, electric fire high-voltage cable.
3. Monitoring system The function of the monitoring system is to allow the burner to operate stably. Its main components are flame monitor, pressure monitor, temperature monitor, etc.
4. Fuel system The function of the fuel system is to let the burner burn the required fuel. The fuel system of the oil burner mainly includes: oil pipes and joints, oil pumps, solenoid valves, nozzles, and heavy oil preheaters. Gas burners mainly include filters, pressure regulators, solenoid valve groups, ignition solenoid valve groups, and fuel butterfly valves.
5. Electronic control system The electronic control system is the command and contact point of the above systems. The main control element is the program controller. Different burners are equipped with different program controllers. Common program controllers are: LFL series, LAL series, LOA The main difference between series and LGB series is the time of each program step.
2. Boiler controller
1. Full Chinese LCD screen, built-in incandescent night light, no matter night or day, the screen content is clearly visible.
2. The image animation shows the water level status, heating status, pump valve status, alarm status, and the boiler operation is clear at a glance.
3, CPU processor, the program is concentrated on a digital chip, with strong expansion, high degree of automation, easy operation and good functions.
4. With multiple control functions such as time setting, temperature setting, pump valve setting, continuous setting, timing setting, pressure setting, etc., the working state can be set arbitrarily.
5. It has multiple alarm functions such as low water level alarm (no dry burning), high water temperature alarm, high pressure alarm and other alarm functions and interlocking protection capabilities (shutdown).
6. Detailed self-diagnosis, recording and storage of alarm information, can check the alarm situation, easy to check and maintain.
