Working Principle Of Gas Furnace
Apr 04, 2026
The operation of a gas-fired boiler begins with the mixing of gas and air. Gas enters the burner through the gas supply line, where it mixes with air in a specific ratio to form a combustible mixture. When the ignition device is activated, the mixture is ignited and continues to burn, releasing a significant amount of heat. To ensure stable combustion, the gas flow rate and air supply are adjusted according to operational needs, maintaining optimal flame combustion.
The heat generated by combustion is then transferred through a heat exchange system. As high-temperature flue gas flows through the heat exchanger, its heat is absorbed and transferred to air, water, or other media requiring heating, thus achieving heat energy utilization. The heat exchanger improves heat utilization efficiency and reduces heat loss, enabling the gas-fired boiler to achieve better heating results with lower gas consumption.
Throughout the entire operation, the control system monitors and regulates the gas-fired boiler in real time. Temperature sensors, pressure sensors, and flameout protection devices continuously monitor the equipment's operating status. When the temperature reaches the set value, the control system automatically adjusts the gas supply; in case of flameout, overheating, or abnormal pressure, the system promptly issues an alarm or cuts off the gas supply, ensuring the safe and stable operation of the gas-fired boiler.
