The 4-ton oil-gas dual-purpose boiler can use either oil fuel or gas fuel. The requirements for fuel adaptability are very low, and it can be used normally in any region of our country. Many users are very interested in the hourly operating cost of the boiler, which is related to the investment cost of the boiler. Zhengzhou Fangkuai Boiler Factory is here to answer everyone.
At present, the thermal efficiency of the 4-ton oil-gas dual-purpose boiler launched by Zhengzhou Fangkuai Boiler Factory can reach more than 98%, which is at least 10% higher than ordinary boilers on the market. It can be said to be very energy-saving, so it runs every hour. The cost is also very low and can be controlled at around 45meijin. Of course, the specific cost depends on the actual usage of the user.
Everyone knows the importance of thermal efficiency to boiler energy consumption. What are the reasons for the low efficiency of boiler operation? Zhengzhou Fangkuai Boiler Factory gave the answer.
The main causes of boiler thermal efficiency problems are: high exhaust gas temperature; low soot blower input rate; large ash and slag combustible materials; excessive or small boiler oxygen; large heat loss; large air preheater leakage rate; high quality of steam and water Poor; The equipment has defects and is forced to run with reduced parameters.
The main measures to solve the above problems are: reduce the exhaust gas temperature; eliminate soot blower defects in time and increase the soot blower input rate; reduce fly ash combustibles and slag combustibles; control boiler oxygen content; reduce heat loss; reduce air preheating Heater air leakage rate; control the fineness of coal to be qualified; improve the quality of steam and water; adjust the layout of the heating surface of the boiler according to the situation; modify the burner if necessary to make it suitable for gas fuel.


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.
