The use of thermal insulation materials in industrial boilers can effectively reduce the heat loss of the boiler, thereby improving the overall operating efficiency of the boiler. Related tests show that compared with boilers that do not use thermal insulation materials, industrial boilers using thermal insulation materials can save at least 20% of the input cost per year, which is enough to see the importance of thermal insulation materials to industrial boilers.
At present, there are many types of insulation materials on the market, mainly rock wool, aluminum silicate fiber cotton, etc.; aluminum chlorate fiber cotton is mostly used for boiler insulation.
So, what is the appropriate range for the thickness of the insulation material used in industrial boilers? The Qiugong of Zhengzhou Fangkuai boiler manufacturer will answer for you.
The insulation thickness of the thermal insulation material selected for industrial boilers needs to be calculated. It needs to be calculated according to the internal temperature, the external surface temperature requirements or the heat loss requirements. The heat preservation of the boiler body and pipes is generally between 100mm-200mm. If you feel this calculation method is more difficult, you can remember this sentence: if the internal temperature is high, keep it thicker, and if the temperature is low, keep it thinner.


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.
