Under the background of carbon peak and carbon neutralization, the importance of thermal power generation in northwest China has been further increased. Due to the high proportion of high alkali coal in this area, serious slagging and contamination come out easily in the process of burning high alkali coal in boiler. It's of vital importance to solve the problem of safe burning of high alkali coal ensuring the safety of electric power in China. The present situation of high-alkali coal combustion technology at home and abroad is introduced in this paper. With more than ten years' research, the high-alkali coal combustion technology in China has been improved remarkably, and the related achievements have been popularized and applied in the electric power industry. The blending ratio of high alkali coal in boiler has been increased from less than 60% to more than 90%, though the full burning of high alkali coal has not been realized yet. This paper introduces different technical routes to realize full burning of high alkali coal and analyzes the equipment parameters and operation of typical boilers burning high alkali coal. Generally speaking, pulverized coal boiler, fluidized bed boiler and liquid slag boiler have their own advantages and disadvantages in the adaptability to high alkali coal, with technical bottlenecks to be further studied and broken through. In order to ultimately solve the high alkali coal combustion problem, more new technologies need to be introduced.

在“碳达峰、碳中和”的大背景下,西北地区火力发电在我国电力行业中的重要性进一步提升。该地区高碱煤占比高,锅炉燃用高碱煤过程中极易出现严重结渣和沾污问题,解决高碱煤安全燃用问题对保证我国电力安全有重要意义。对国内外高碱煤燃用技术发展现状进行了介绍,通过十余年的研究,我国高碱煤燃烧技术取得了显著的进步,相关成果已经在电力行业得到了推广应用,锅炉高碱煤掺烧比例由60%以下提高到了90%以上,但目前仍未能完全实现全烧高碱煤。对实现全烧高碱煤的几种技术路线进行了介绍,同时对目前燃用高碱煤典型锅炉的设备参数及运行情况进行了介绍分析。总体而言,煤粉锅炉、流化床锅炉、液态排渣锅炉在对高碱煤适应性方面各有优缺点,都还有技术瓶颈需要进一步研究和突破。为最终破解高碱煤安全燃用难题,还需要引入更多的新技术。

在“碳达峰、碳中和”的大背景下,西北地区火力发电在我国电力行业中的重要性进一步提升。该地区高碱煤占比高,锅炉燃用高碱煤过程中极易出现严重结渣和沾污问题,解决高碱煤安全燃用问题对保证我国电力安全有重要意义。对国内外高碱煤燃用技术发展现状进行了介绍,通过十余年的研究,我国高碱煤燃烧技术取得了显著的进步,相关成果已经在电力行业得到了推广应用,锅炉高碱煤掺烧比例由60%以下提高到了90%以上,但目前仍未能完全实现全烧高碱煤。对实现全烧高碱煤的几种技术路线进行了介绍,同时对目前燃用高碱煤典型锅炉的设备参数及运行情况进行了介绍分析。总体而言,煤粉锅炉、流化床锅炉、液态排渣锅炉在对高碱煤适应性方面各有优缺点,都还有技术瓶颈需要进一步研究和突破。为最终破解高碱煤安全燃用难题,还需要引入更多的新技术。

Under the background of carbon peak and carbon neutralization, the importance of thermal power generation in northwest China has been further increased. Due to the high proportion of high alkali coal in this area, serious slagging and contamination come out easily in the process of burning high alkali coal in boiler. It's of vital importance to solve the problem of safe burning of high alkali coal ensuring the safety of electric power in China. The present situation of high-alkali coal combustion technology at home and abroad is introduced in this paper. With more than ten years' research, the high-alkali coal combustion technology in China has been improved remarkably, and the related achievements have been popularized and applied in the electric power industry. The blending ratio of high alkali coal in boiler has been increased from less than 60% to more than 90%, though the full burning of high alkali coal has not been realized yet. This paper introduces different technical routes to realize full burning of high alkali coal and analyzes the equipment parameters and operation of typical boilers burning high alkali coal. Generally speaking, pulverized coal boiler, fluidized bed boiler and liquid slag boiler have their own advantages and disadvantages in the adaptability to high alkali coal, with technical bottlenecks to be further studied and broken through. In order to ultimately solve the high alkali coal combustion problem, more new technologies need to be introduced.
