Working Principle of Gas Wall-Hung Boilers
When it comes to wall-mounted gas boilers, I’m sure everyone knows that they play a crucial role in winter by using natural gas to produce hot water. However, when using a gas wall-mounted boiler, it’s important to make the right choice; otherwise, the heating performance in the later stages may be very poor. So how does a gas wall-mounted boiler work? Let me explain it to you now. The operating principle of a gas wall-mounted boiler is as follows: When the ignition switch is turned on, the fan starts up, creating a negative pressure differential inside the combustion chamber. This triggers the air-pressure switch to send a signal to the circulating pump, which then starts. Once the pump is running, the water-flow switch sends a signal to the high-pressure safety device and to the gas proportional valve, causing the latter to activate. Thanks to the negative pressure in the combustion chamber, natural gas is prevented from pooling and igniting unevenly, and detonation is avoided, resulting in quiet, ultra-silent ignition and minimizing the risk of hazardous accidents. This design ensures the boiler’s operational stability. Furthermore, the gas proportional valve, air-pressure switch, and flue-gas draft control switch operate under interlock control: only when the combustion chamber maintains a certain level of negative pressure can the gas proportional valve function. If, within five seconds, the flue-gas draft control switch fails to detect proper exhaust discharge, it will immediately shut off the gas proportional valve and stop the gas supply, thereby guaranteeing safe operation.
