The main components of a gas boiler are gas burner and boiler controller.

I. Gas burner

Gas burner structure consists of the following five systems:

1, air supply system air supply system function is to the combustion chamber into a certain wind speed and air volume of the air, its main components are: shell, fan motor, fan impeller, air gun fire tube, damper controller, damper plate, cam adjusting mechanism, diffusion disk. 2, ignition system ignition system function is to ignite the mixture of air and fuel, and its main components are: ignition transformer, ignition electrodes, electrical fire high-voltage The function of monitoring system is to ensure the safe and stable operation of the burner, and its main components are flame monitor, pressure monitor, temperature monitor, etc. 4, fuel system fuel system function is to ensure that the burner combustion of the fuel required. The fuel system of the oil burner mainly has: oil pipe and connector, oil pump, solenoid valve, nozzle, heavy oil preheater. Gas burners are mainly filters, regulators, solenoid valves, ignition solenoid valve group, fuel butterfly valves. 5, the electronic control system electronic control system is the command center of the above systems and contact centers, the main control elements for the programmable controller for different burners with different programmable controllers, common programmable controllers are: LFL series, LAL series, LOA series, LGB series, the main difference between the individual The main difference is that the time of each program step is different.

Second, the boiler controller

1, large Chinese LCD display, built-in incandescent night light, no matter night and day, the screen content is clearly visible. 2, the image animation shows the water level status, heating status, pump valve status, alarm status, boiler operation at a glance. 3, CPU intelligent central processing unit, all programs are concentrated in a digital chip, scalable, high degree of automation, easy to operate, powerful. 4, with time, temperature setting, pump and valve settings, the pump and valve settings, the time of day, the time of day, the time of day, the time of day, the time of day, the time of day, the time of day, the time of day, the time of day, the time of day. Setting, temperature setting, pump valve setting, continuous setting, timer setting, pressure setting and other control functions, arbitrary setting of the working state. 5, with a very low water level alarm (anti-dry burning function), water temperature alarm, pressure alarm, such as ultra-high alarm and chain protection capabilities (shutdown), to eliminate potential safety hazards. 6, detailed self-diagnostics, recording, storing the alarm information, alarm can be accessed at any time, checking and maintenance. Convenient maintenance.
