Abstract

An investigation of co-combustion characteristics of the two-component mixed fuel was carried out using methods of thermogravimetric analysis. As feedstock, there were used two types of biomass and the high-ash coal-containing waste, which were ash-slag waste from a coal-fired power plant and coal concentrate obtained by their enrichment. The experiments were carried out in an inert (nitrogen) and oxidizing (air) medium. It is shown, that in the temperature range characteristic for biomass burning the additivity principle cannot be used for evaluation of combustion characteristics of the blends. The presence of a coal-containing component in the mixture leads to a disproportionate decrease in the mass loss rate both in the temperature range characteristic for yield and oxidation of biomass volatile products, and in the temperature range in which its solid residue is oxidized. The effect of biomass on the oxidation rate of the coal-containing component was not found.

生物质与高灰分含煤废物混合燃料的热重分析

摘要

使用热重分析法对二组分混合燃料的燃烧特性进行了研究。作为原料，使用了两种生物质和高灰分含煤废物，分别是燃煤发电厂的灰渣废物和通过富集得到的精煤。实验在惰性（氮气）和氧化（空气）介质中进行。结果表明，在生物质燃烧的温度范围内，加和原理不能用于评估共混物的燃烧特性。混合物中含煤成分的存在导致质量损失率在生物质挥发性产品的得率和氧化特性的温度范围内不成比例地降低，在其固体残留物被氧化的温度范围内。没有发现生物质对含煤组分的氧化速率的影响。
