Abstract

Fuel economy in boilers is an urgent concern. Coal combustion with fuel oil is currently employed for that purpose, but this approach impairs electricity generation and releases oxides of sulfur and nitrogen into the environment. An alternative is oil-free combustion with plasma activation of the coal. Preliminary plasma activation results in more efficient combustion in the absence of fuel oil. The effectiveness of this technology is confirmed by familiar methods: engineering analysis, economic assessment, elaboration of a theory, experimental testing, and formulation of recommendations for optimizing the technology. The influence of plasma activation on the coal combustion is studied. The resulting technology for thermal preparation and combustion of coal in a cyclone furnace is an alternative to combustion with fuel oil in industrial boilers. The design of the system for regulating combustion with partial gasification of the working fuel is improved. Using this technology, it proves possible to use low-grade coal as the fuel. The emission of nitrogen oxides is decreased, and boiler performance is improved. Oil-free fuel combustion in a cyclone furnace is promising for use in power generation. It is shown that coal combustion with chemical activation or high-temperature plasma activation may be used in modernizing or constructing thermal power stations.

旋流炉中煤的无油燃烧
锅炉的燃油经济性是一个迫切需要关注的问题。目前使用的方法是用煤燃烧燃料油,但这种方法会损害发电,并向环境中释放硫和氮的氧化物。另一种选择是用等离子体活化煤的无油燃烧。在没有燃料油的情况下,初步的等离子体激活可以提高燃烧效率。该技术的有效性通过熟悉的方法得到证实:工程分析、经济评估、理论阐述、实验测试和优化技术的建议。研究了等离子体活化对煤燃烧的影响。由此产生的在旋风炉中热制备和燃烧煤的技术是工业锅炉中燃料油燃烧的替代技术。对工作燃料部分气化调节燃烧系统的设计进行了改进。利用这一技术,证明使用低品位煤作为燃料是可能的。减少了氮氧化物的排放,提高了锅炉的性能。无油燃料在旋风炉中的燃烧在发电中具有广阔的应用前景。研究表明,煤的化学活化或高温等离子体活化可用于火力发电站的现代化或建设。
