Description

Technical Field

[0001] This utility model relates to a flame stabilizing device for the combustion chamber of a wall-hung boiler, belonging to the technical field of flame stabilizing devices. Background Technology

[0002] A wall-hung boiler is a heating system that uses natural gas, liquefied petroleum gas (LPG), or electricity as its energy source, and is widely used in residential and commercial buildings. Its working principle involves generating heat through gas combustion or electric heating, then transferring the heat to water via a heat exchanger to provide indoor heating and domestic hot water. With increasing awareness of energy conservation and environmental protection, wall-hung boilers have adopted advanced combustion technology, thermal efficiency control systems, and intelligent adjustment functions, significantly improving the energy utilization rate and operational stability of the equipment. Furthermore, wall-hung boilers are compact, flexible in installation, and easy to operate, making them an important solution for modern families' heating and hot water needs.

[0003] The induced draft fan in existing wall-hung boiler flame stabilization devices typically cannot adjust its distance from the flame, which leads to several drawbacks. First, the fan's speed and volume are fixed, making it impossible to adjust the airflow distribution in real time according to flame changes, thus limiting flame stability. When the load changes or the gas supply fluctuates, the flame may become unstable, affecting combustion efficiency and heat exchange. Second, the fixed airflow and speed may cause overheating or uneven cooling in some areas, further affecting the uniformity and efficiency of the combustion process. This unadjustable design limits the equipment's adaptability to different operating conditions, increases energy consumption and maintenance costs, and may also reduce the overall safety and reliability of the equipment.

[0004] To address this, a flame stabilization device for the combustion chamber of a wall-hung boiler is proposed. Utility Model Content

The combustion baffle 108 of flame-sensing needle 107 creates a combustion chamber inside, and heat exchanger 109 exchanges the heat generated by flame-sensing needle 107. The induced draft fan 208 generates suction, and the airflow and flue gas in the combustion chamber are drawn into the flame stabilizer box 203 through the air inlet 214. The flame generated by the flame-sensing needle 107 is affected by the guided airflow, making the flame more stable during combustion. The exhaust gas generated during combustion is discharged through the guide tube 209 to avoid pollution of the external environment. The threaded connection between the inspection plate 211 and the flame stabilizer box 203 makes it convenient for staff to inspect and maintain the equipment.
