The introduction of new environmental protection laws and boiler air pollution control standards is standard in China's approach to the increasingly strict atmospheric environmental management road. Coal-fired boilers are the main target of environmental protection department management, and coal-fired boiler renovation projects are also being carried out everywhere. Many people will choose to change the coal-fired boiler to a gas-fired boiler. This is not only because the natural gas is cleaner and more environmentally friendly, but the thermal efficiency of the modified boiler will also increase by about 15-20%, which can save the company a lot of fuel input costs.
In addition to the selection of high-quality coal-fired boiler retrofit companies, special attention must be paid to the following items.
1. Precautions for boiler removal
In order to carry out the transformation of the coal-fired boiler, it is necessary to dismantle some parts of the existing boiler; when removing the boiler, it is necessary to turn off the blower to stop its operation. When the boiler furnace temperature drops to a suitable temperature, stop the boiler induced draft fan, the chain grate, and then The worker enters the furnace from the fire door, removes the original furnace arch of the boiler, cleans the inside of the furnace, and then removes the boiler main engine and auxiliary machine.
2. Furnace renovation considerations
Furnace is a key point in the work of transforming coal-fired boilers. Through reasonable transformation, the combustion conditions of existing boilers can be improved, so that they not only meet the combustion conditions of new fuels, but also better play an energy-saving role. However, during the transformation, it involves the recasting of the furnace. Therefore, special attention should be paid during this transformation process to keep the rear arch tube of the original boiler away from the center of the flame to avoid high temperature burning.
3. Reconstruction test precautions
When the transformation of coal-fired boilers is carried out through a series of projects such as furnace reformation and pouring of new boiler front arch and arch, it is necessary to pay attention to the test of the modified boiler. One of the most important tests is to test the water pressure of the boiler body under a certain pressure. Only after passing the test and transformation, the boiler can be put into use.
The above is the three important items that should be paid attention to when the coal-fired boiler is changed to a gas boiler. The quality of the coal-fired boiler transformation company can be modified according to the characteristics of the boiler itself and the needs of the enterprise, and strive to achieve perfect energy-saving and consumption-reducing effect. However, because the boiler has pressure during use, it must be after the transformation is completed. Pay attention to the relevant tests to avoid potential safety hazards.
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.
