The burner is a combustion device of a gas boiler. A good burner can realize automatic ignition, monitoring of combustion status, protection against ignition, flameout protection, high and low pressure protection of gas pressure, protection against insufficient air pressure, and power failure protection. What role can these functions play? Listen to FANGKUAI Boiler to introduce you one by one.
1. Automatic ignition function
The gas burner should be equipped with electric spark ignition, which is convenient for automatic control. The ignition time is generally between 2 and 5 seconds.
2. Combustion status monitoring function
Mainly monitor the flameout state of the gas boiler burner, and the monitoring object is the flameout signal. Once the flame detector detects this signal, the burner will automatically cut off the air supply and the burner will stop running.
3. The burner does not catch fire, automatic protection function
When the gas boiler burner is ignited. The ignition action occurs before the ventilation. After the ignition action occurs, if the human flame detector does not detect the flame signal, the burner automatically enters the protection state.
4. Burner flameout protection
After the burner is turned off, the temperature in the furnace of the gas boiler is still relatively high, the burner will stop running in a short time, and the supply of the gas source is automatically cut off to prevent excessive gas from entering the furnace and causing an explosion.
5. Gas pressure high and low protection
The gas boiler burner will operate within a certain range of gas pressure, above or below this range, the burner will enter the protection state.
6. Air pressure protection function
When the gas boiler burner is running, if the amount of air in the furnace is insufficient, it will always be inhaled, which will cause the furnace to deflagrate, which is very dangerous. Therefore, once the air in the furnace is insufficient, the burner will automatically enter the protection state.
7. Burner power failure protection function
When the gas boiler burner is in operation, if it is suddenly powered off, it will be very dangerous. Therefore, the burner is provided with power failure protection.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.

Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.

Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
