TN型双通道燃烧器在燃用劣质煤锅炉中的应用
Application of TN-type double channel burner in the low-quality coal-fired boiler
【摘要】 针对当前电煤价格升高、煤质下降,许多电厂在燃用劣质煤时,锅炉出现频繁灭火、管壁超温、投油助燃等问题,研制了TN型双通道燃烧器。TN型双通道燃烧器是在原双通道燃烧器原理基础上,增加了“多突扩”和“煤粉浓缩”技术,使更多的煤粉在燃烧器中预热、预燃,其稳燃能力更强。应用TN型双通道燃烧器,可大大提高锅炉的稳燃能力和煤质适应性,降低锅炉助燃油用量,使锅炉运行的安全性和经济性均得到大幅提高,为电力企业降低发电成本提供可靠的技术保障。
【Abstract】 With the increasing of coal price and decreasing of coal quality,the operation problems occur in boiler operation such as the frequent fire extinguishing,over temperature in pipe wall and more combustion-supporting oil etc.TN-type double channel burner was developed based on the original double channel burner by introducing Pulverized-coal Concentration and Multi-sudden Expansion Technologies.It makes more pulverized coal preheated and pre-burned so as to improve the stability of combustion.The application of such burner can greatly increase the combustion stability,coal adaptability and reduce the required combustion-supporting oil.The safety and economy of boiler operation can be improved significantly,providing reliable technical support for the cost cutting in power generation.
