Condensing technology is a new energy-saving and environmentally friendly technology, and it is the key to improving the efficiency of condensing oil and gas boilers. The principle of condensing technology is not complicated. A simple summary is to recover the heat energy in the flue gas by condensing the flue gas. Zhengzhou Fangkuai Boiler Factory will explain in detail the application of condensing technology to effectively improve the operating efficiency of oil-fired and gas-fired boilers.
The exhaust gas temperature of traditional boilers is generally around 160~250℃ or even higher, so that the water produced during fuel combustion (such as natural gas: CH4+2O2→CO2+2H2O) is in the superheated state of water vapor in the flue gas, and the smoke Gas is lost from the chimney. The thermal efficiency of traditional boilers can only reach 85%~91%. The condensing gas boiler reduces the exhaust gas temperature to 50~70℃, fully recovers the sensible heat in the flue gas and the condensation latent heat of water vapor, and the thermal efficiency can reach up to 109%.
The core of the condensation technology is to reduce the heat loss of fuel combustion and efficiently absorb the heat generated by the fuel. At the same time, due to the condensation of the flue gas, the harmful substances in the flue gas are collected into the condensed water, reducing acidic substances and other pollutants into the air. emission. More advanced condensing gas boilers use smokeless combustion technology, which reduces the emission of nitrogen oxides (NOx can cause acid rain and greenhouse effect) to beyond 35mg/kwh.
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.
