The boiler is a device that consumes a lot of energy, and the energy-saving device of the gas boiler is born based on this. In order to save energy, the waste heat of the high-temperature flue gas discharged from the boiler is reused. The manufacturer installs the economizer near the tail of the boiler or near the top flue, which is a component for heating the water supply. The gas boiler installed with the economizer can improve the efficiency of the boiler by lowering the exhaust gas temperature, thereby achieving the purpose of saving fuel.
Classification of energy savers:
Depending on the application and the exchange medium, the energy saver is mainly divided into flue gas-liquid boiler economizer, flue gas-air boiler economizer and all stainless steel 304 frame plus stainless steel spiral finned tube (high frequency welded pipe), which has fast heat transfer. , energy saving, durable and so on.
The energy-saving device produced by FANGKUAI Boiler uses a spiral finned tube structure with high heat exchange, which increases the heat exchange area by 5 times compared with the ordinary light pipe heat exchange, and the heat exchange rate is directly increased by about 5 times. It not only meets the energy-saving requirements of boiler operation, but also saves a lot of use area.
Generally speaking, the price of the energy-saving device of the gas boiler is related to various factors such as the volume of the boiler body and the expected effect. If you want to know the specific price of the energy-saving device, you need to communicate with professional technicians according to your own needs.
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.
