Through the policies issued by various provinces and cities in my country in recent years, it can be seen that my country’s current environmental protection requirements are becoming more and more stringent. Some areas in Beijing have reached the regional emission standard of 30 mg/m3, which is important for sustainable development. Is very helpful. In combination with the current environmental protection policies, great changes have also taken place in the boiler industry. More and more companies require the use of low-nitrogen-emission boilers, while traditional boilers have high pollution rates, large area, and inconvenient use. Multiple shortcomings are gradually eliminated. So, compared with traditional boilers, what are the outstanding advantages of gas-fired low-nitrogen boilers? Let Zhengzhou Fangkuai Boiler Factory provide you with comprehensive answers.
1. The difference in emissions between traditional boilers and gas-fired low-nitrogen boilers
Due to the different combustion methods and furnace structures of stratified, chamber, and circulating fluidized bed boilers, the nitrogen oxide (NOx) emissions of these two types of boilers are also quite different. Generally speaking, when using low nitrogen combustion in the furnace In terms of technology, the original NOx emission of the circulating fluidized bed is low, and the original NOx emission of the layer-burning furnace represented by the chain furnace is slightly lower. The pulverized coal industrial boiler is a room-fired boiler. The higher the original NOx emission, the higher the emission of the domestic low-nitrogen boiler. But greatly reduced.
2. Traditional boilers and gas-fired low-nitrogen boilers use different technologies
Stratum fired, chamber fired, and circulating fluidized bed boilers can adopt different low-nitrogen combustion technologies according to different combustion methods. For stratified fired boilers, air classification and flue gas recirculation are often used to achieve low-nitrogen combustion; Under the influence of recirculation on the combustion of the typical section of the stratified combustion boiler, combined with the air classification technology, the NOx is catalytically reduced by semi-coke; the furnace reduction denitrification technology is an emerging furnace denitrification technology in recent years, and the combustion flame area is sprayed at a reasonable position Ammonia, to achieve direct denitration in the high temperature flame. Low-nitrogen boilers mainly adjust the position and distribution of secondary air outlets and coal feed outlets, or increase flue gas recirculation systems.
3. The safety of traditional boilers and gas-fired low-nitrogen boilers is different
After a large number of experiments on the low-nitrogen combustion technology in the furnace of stratified, room-fired, and circulating fluidized bed boilers, they have been verified in engineering applications. Generally speaking, low-nitrogen boilers have higher safety and are also used by many users. The reason for choosing it.
It can be seen that the gas-fired low-nitrogen boiler is a kind of product that is truly energy-saving and environmentally friendly. The low-nitrogen boiler technology adopted by it has been verified by many tests and engineering applications, and has achieved significant results, not only protecting the environment, but also As far as the users are concerned, energy saving is also achieved, which is a double effect.
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.
