Temperature protection of boiler water is one of the important measures to ensure the safety of boiler operation. It is necessary to provide multiple water temperature protection for each boiler to ensure that the boiler water temperature fluctuates within the normal range. The following are some water temperature protection measures.
1. Water temperature protection
An outlet water temperature detecting sensor (thermal resistance or thermocouple) is arranged on the boiler outlet side to detect the water temperature in real time to ensure that the outlet water temperature does not exceed the rated value.
2. Secondary overheat protection
In the boiler body design secondary heat-off protection, if it is detected that the furnace temperature exceeds the set value, immediately cut off the main power supply, prohibiting the boiler temperature from rising further.
3. Over temperature alarm parallel lock protection
When the boiler temperature exceeds the limit value, the over-temperature alarm device is activated to prompt the furnace worker to troubleshoot the fault.
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.
