Gas-fired steam boiler is one of the common equipment in industrial production and processing industries. The boiler uses natural gas as fuel. It is very convenient for transportation, installation and later use. It only needs to build water, electricity, and gas pipelines and it can be started and used normally. The boiler adopts low-nitrogen combustion technologies such as FGR and full premixing, and the pollutant emission can be as low as 30 mg/m3.
Many users are more concerned about the price of gas-fired steam boilers. Zhengzhou Fangkuai Boiler Factory takes a 1-ton gas-fired steam boiler as an example to provide answers for everyone. The current market price of a 1-ton gas-fired steam boiler ranges from US$10,000 to US$10,000, depending on the configuration of the boiler, but in general it is within this range.
Zhengzhou Fangkuai Boiler Factory also reminds everyone to pay attention to the use of blowdown expansion vessels on the boiler.
In the boiler equipment, the function of the blowdown expansion vessel is: when the boiler sewage is discharged into the expansion vessel, the volume expands, the pressure decreases, and the saturation temperature also decreases accordingly. Part of the waste water under the original pressure is released after the pressure is reduced. This part of the heat is absorbed by the water as the heat of vaporization and part of the sewage is vaporized. The vaporized part of the steam is introduced into the deaerator for recovery. This part of steam and heat.
The blowdown expander is also called blowdown expansion vessel, and its design and manufacture should be carried out according to GB150-98 of pressure vessel. The continuous blowdown expander is connected to the continuous blowdown port of the boiler. It is used to decompress and expand the continuous blowdown of the boiler. The blowdown is adiabatically expanded in the continuous blowdown expander and separated into secondary steam and waste hot water. After the internal expansion, pressure reduction, heat exchange, and then discharge, the secondary steam is led out by a special pipeline, and the waste hot water is automatically discharged through the float level valve or overflow regulating valve, and the heat energy can be recycled and reused. The continuous blowdown volume is automatically adjusted with the change of the boiler feed water load to maintain a relatively stable blowdown rate.
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.
