For industrial boilers, the energy efficiency index refers to the use of thermal efficiency index values equivalent to the CIBB2-2009 "Technical Conditions for Energy-saving Products for Industrial Boilers" (Industrial Boiler Branch of China Electrical Equipment Industry Association). To see whether all aspects of the performance of industrial boilers are intentional, just look at the data of energy efficiency indicators. It depends on the specific energy efficiency indicators, and let Zhengzhou Fangkuai Boiler Factory tell you the answer.
1. The slag combustible content index: calculate according to the analysis of representative coal types to determine the appropriate index value.
2. The temperature rise index of the outer surface of the furnace: use the outer surface temperature rise index of the furnace instead. The main assessment is the temperature difference between the outer surface of the furnace and the ambient temperature. It is more scientific and reasonable to use the temperature rise index to eliminate errors caused by changes in ambient temperature in winter and summer.
3. The exhaust gas temperature index of coal-fired boiler: It is consistent with the index of GB/T17954-2007 "Industrial Boiler Economic Operation".
4. Index of excess air coefficient at exhaust gas of coal-fired boiler: consistent with the index of GB/T17954-2007 "Economic Operation of Industrial Boilers".
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.
