The combustion method of the boiler equipment is also a factor that the majority of users will consider when selecting the boiler. Depending on the combustion method, the boiler structure and boiler room layout will be different. Today, Zhengzhou Fangkuai boiler manufacturer will briefly introduce to you, what are the more common combustion methods of boiler equipment at present.
1. Diffusion combustion
Advantages: This kind of combustion method is to mutually diffuse the gas at the nozzle mouth without pre-mixing, and then burn it. The combustion method is relatively simple, and the flame is relatively stable.
Disadvantages: Due to the long flame, it is easy to produce incomplete combustion, which will produce more carbon monoxide and nitrogen oxides, which is not conducive to the full use of boiler fuel, the improvement of boiler thermal efficiency, and it is difficult to reach boiler emission standards.
2. Fully premixed combustion method
Advantages: pre-mixing air and gas, heat transfer with multiple radiators, and increased heat transfer intensity. The advantage of using this combustion method is that the burning flame is clearer and the thermal efficiency is higher. Disadvantages: Combustion premixing ratio requires fast combustion rate, uniform combustion, high radiation heat transfer efficiency, flame temperature lower than 1200℃, no incomplete combustion and low NOx flue gas temperature, easy to condense, good heat recovery, and high efficiency.
3. Flameless combustion
A combustion method that uniformly mixes the space before combustion with the gas in the gas boiler. When using this method, the oxygen required during the combustion process of the gas does not need to be obtained from the surrounding air, and only needs to be mixed with the air to reach the combustion zone to achieve instantaneous combustion completion.
It can be seen that there are currently three common combustion methods for boiler equipment. When purchasing a boiler, you can compare the advantages and disadvantages of the combustion method to select suitable boiler equipment.
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.
