Both coal-fired boilers and gas-fired boilers are relatively common types in the boiler market in recent years. Although they are more consistent in their comprehensive performance, they have specific combustion methods, combustion products, and specific operational requirements and workflows. A big difference, FANGKUAI Boiler after ample market research, summed up the main differences between coal-fired boilers and gas-fired boilers.
First, the way of burning
Most of the coal-fired boilers use the layer-fired combustion method. The coal passes through the coal-feeding machine to transport the chain grate plane, and the combustion process is completed in the furnace. Most of the gas boilers use chamber combustion, and the natural gas is mixed with the air in the burner in a predetermined ratio, and then injected into the furnace through the nozzle to complete the combustion in the furnace state.
Second, the automatic control of the boiler
Coal-fired boilers are limited by factors such as coal type, coal seam thickness, blast volume, air volume, air volume distribution and grate speed. It is difficult to automatically adjust boiler operating parameters according to load. However, high-quality gas boilers are less affected, and only the size of the burner can be adjusted according to the load, and automatic control is easy.
Third, the combustion products
Coal is mainly composed of C, H, O, N and other elements, ash and moisture, but not the surface of these components, but a more complex compound. After the coal is burned, heat is released, and sulfurized oxygen gas is generated, which is discharged into the atmosphere by the flue gas. These gases are very polluting the environment and cause harm to humans. The natural gas used in gas boilers is mainly composed of methane gas and contains a small amount of non-hydrocarbon gas. Generally, it does not contain water and ash. Therefore, it mainly produces carbon dioxide and water after combustion, and releases a large amount of heat. Compared with coal, Hazardous substances should be significantly reduced.
Due to the difference in fuel, coal-fired boilers and gas-fired boilers show many differences in many specific ways of use and work content. Therefore, in the process of selecting the two, it is necessary to choose according to the needs and convenience of operation.
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.
