What is the working principle of traditional gas wall-hung boilers
The principle of gas-fired wall-hung boilers is not complicated. A negative pressure difference is formed in the combustion chamber, and the air pressure switch sends the command to the water pump. After the water pump starts, the water flow switch sends the command to the high-pressure arrester. After the start, the command is sent to the gas proportional valve, and the gas proportional valve starts to start. Due to the existence of negative pressure in the combustion chamber, the natural gas does not gather the imagination of combustion, so there will be no deflagration imagination, realize the quiet ignition and ultra-quietness, and also ensure the dangerous accident. This standard can identify the stability of the furnace. Some customers are worried about gas safety because they do not understand the operation control principle of the gas proportional valve of the wall-hung boiler. The gas proportional valve, the air pressure switch and the flue gas induction switch are controlled in a chain, and the combustion chamber must have a certain negative pressure gas proportional valve. Work, when the 5-second flue gas sensor switch does not detect exhaust gas, it will cut off the gas proportional valve to stop the gas supply, so as to ensure the safe use of gas.
How does a home condensing boiler work
How does a condensing boiler work? The condensing gas wall-hung boiler realizes heating by fully absorbing the sensible heat and the latent heat of water vapor in the flue gas through two heat exchangers. The calorific value of the gas refers to the heat released by the complete combustion of 1Nm3 of gas. The calorific value is divided into high calorific value and low calorific value. The high calorific value refers to the heat released when the flue gas of 1Nm3 gas is completely cooled to the original temperature, and the water vapor in it is discharged in the state of condensed water; the low calorific value refers to the 1Nm3 gas The heat released when the flue gas is cooled to the original temperature after complete combustion, but the water vapor in the flue gas is still in the vapor state. It can be seen that the difference between the high calorific value and the low calorific value of the gas is the latent heat of vaporization of water vapor.
Because the domestic wall-hung boilers have not developed for a long time, many people do not know much about wall-hung boilers, especially in the central and southern regions. People will also have many questions about the technology of wall-hung boilers. By understanding the working principle of wall-hung boilers, we can understand the performance of wall-hung boilers as a whole. In addition, the brand selection of wall-hung boilers is also very important. Condensing wall-hung boilers are the future development direction. , Although the current price of condensing wall-hung boilers is relatively high, from the perspective of long-term values, condensing wall-hung boilers are obviously more in line with the needs of energy saving and environmental protection.
