本文从节能和环保方面讨论了层燃工业炉窑燃用型煤的必要性和合理性。我国在工业锅炉和机车锅炉上进行的试验表明:燃用型煤比燃用混煤其燃烧效率可提高10%左右,烟气中的含尘量和含硫量可减少一半,致癌物苯并(α)芘的含量也有所降低。文章最后从层燃的特点详细论述了沥青质型煤的燃烧特性。文本为层燃工业炉窑利用和推广燃用型煤提供了理论依据和实用指导。
This article discusses the necessity and rationality of burning coal briquette in industrial furnaces with energy saving and environmental protection. Experiments carried out on industrial boilers and locomotive boilers in China show that the combustion efficiency of coal-fired briquette is about 10% higher than that of coal-fired briquette, and the dust content and sulfur content in flue gas can be reduced by half. (α) pyrene content also decreased. In the end, the burning characteristics of bituminous coal are discussed in detail from the characteristics of layer burning. The text provides a theoretical basis and practical guidance for the utilization of flames burning industrial kilns and the promotion of coal burning.
