Nitrogen oxide is one of the main sources of pollution causing air pollution. It is extremely destructive to human body, animals and plants, and the environment. Excessive emission of nitrogen oxides will directly threaten our lives.
Nitrogen and oxygen are not actively mixed together, but when the temperature reaches 1600 ° C, nitrogen and oxygen in the air are mixed to form nitrogen oxides.
At present, the low-nitrogen combustion technology of the gas boiler with better effect has full premixing and FGR.
First, full premixed combustion technology.
Before the fuel is sent to the furnace for combustion, it is thoroughly mixed with the air beforehand, and the optimal ratio is achieved through precise adjustment and control. After adding surface combustion technology, the combustion temperature in the furnace is further reduced to reduce the role of nitrogen oxides.
Second, FGR combustion technology.
FGR combustion technology is the flue gas recycling technology. The flue gas generated after the boiler is operated enters the furnace through the connecting pipe to participate in the combustion, and reduces the combustion temperature of the fuel in the furnace to reduce the role of nitrogen oxides.
If you are in the low-nitrogen reform of the headache boiler or want to buy a low-nitrogen boiler at this time, you can contact the FANGKUAI Boiler through the free service hotline above, we will be happy to help you.
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.
