Abstract Peat belongs to the slowly renewable biomass resources, therefore its use as an energy source helps to reduce the negative impact on the environment. However, its use in the energy sector is gradually decreasing due to high operating costs because of the characteristics of peat. The aim of this work is a comprehensive study of the peat characteristics and the development of recommendations for its effective use. In this paper, we consider the widespread methods for studying fuel (thermo-technical and fusibility characteristics determination, X-ray fluorescence and phase methods), as well as the original approach of separation by sedimentation in liquids of various densities. The peat separation by sedimentation in liquids of various densities made it possible to obtain a low-ash peat fraction comparable in characteristics to brown coals and a highly mineralized fraction (heavy fraction). On the example of grain processing waste, it is shown that the addition of a 5% of heavy peat fraction to bran prevents the formation of strong slag deposits and can be recommended for co-burning. This allows us to consider the separation by sedimentation in liquids of various densities as an effective tool for using highly mineralized types of biomass in energetic sector.

高度矿化泥炭沉积产物作为能源的研究

摘要 泥炭属于可缓慢再生的生物质资源，因此将其用作能源有助于减少对环境的负面影响。然而，由于泥炭的特性，由于运营成本高，其在能源领域的使用正在逐渐减少。这项工作的目的是对泥炭特性进行全面研究，并提出有效利用泥炭的建议。在本文中，我们考虑了研究燃料的广泛方法（热技术和熔融特性测定、X 射线荧光和相法），以及在各种密度的液体中通过沉淀进行分离的原始方法。通过在各种密度的液体中沉淀来分离泥炭，可以获得与褐煤特性相当的低灰分泥炭部分和高度矿化部分（重部分）。在谷物加工废料的例子中，表明在麸皮中添加 5% 的重泥炭部分可以防止形成强烈的炉渣沉积物，可以推荐用于共烧。这使我们能够考虑在不同密度的液体中通过沉降进行分离，作为在能源部门使用高度矿化类型生物质的有效工具。
