1. Furnace: A value that ensures that the boiler fuel is burned out and the outlet flue gas temperature is cooled to a safe working condition on the convective heating surface.
2. Drum: The heating surfaces of the boiler are connected together and form a water circulation loop with the water cooling wall and the descending pipe. The drum is stored in soda water, which can adapt to load changes. There is a steam-water separation device inside to ensure the quality of the steam and water. The DC boiler has no drum.
3. Water wall: the main radiation heating surface of the boiler, absorb the radiant heat of the furnace, heat the working medium, protect the furnace wall and so on.
4. Combustion equipment: The fuel and the air required for combustion are sent to the furnace and the fuel is ignited and burned well.
5. Air preheater: heat the air for fuel to enhance ignition and combustion; absorb residual heat of flue gas, reduce exhaust gas temperature, and improve boiler efficiency.
6. Furnace wall: is the protective casing of the boiler, sealing and heat preservation. Heavy-duty furnace walls for small boilers can also function as support for boiler components.
7. Frame: Support and fix boiler components.
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.
