Gas-fired steam boilers produce more or less scale after a long period of operation.
When a gas-fired steam boiler is in operation, a series of chemical and physical reactions occur in the furnace. During use, hard and dense scales are formed on the heated surface, which directly leads to a decrease in heat exchange efficiency of the boiler; The effect of corrosion under scale will result in reduced heat absorption of the water-cooled fireplace of the gas-fired boiler, thereby reducing thermal efficiency and wasting input costs.
Another need to clean up the scale is to keep the boiler running for a long time.
The thermal conductivity of scale is only one percent of the steel. Once the surface is fouled by the hot surface, the heat transfer effect is hindered. In order to maintain a certain output of the boiler during use, the temperature on the fire side must be increased. The outlet temperature of the furnace of the gas steam boiler is increasing, which will increase the loss of the gas steam boiler, and the scale in the water wall of the equipment will effectively reduce the heat transfer effect, which is very likely Will cause the temperature of the wall of the water wall to increase, causing the water wall to burst.
Cleaning the boiler becomes even more important. In the process of cleaning, high-efficiency, environmentally-friendly and non-corrosive cleaning agents can be used, which will cause the equipment tubes to reveal the original metallic color and reduce the influence of scale.
Secondly, after the ignition of the gas steam boiler, it is necessary to pay attention to observe the temperature of the furnace and the temperature change of the main steam; when the main steam pressure is rising, if the boiler is ignited, the speed of the rise of the smoke temperature will be significantly slow or not rising, immediately Check the oil gun's fire.
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.
