Abstract

The purpose of the research is to evaluate the relevance of using miscanthus energy culture as biomass for burning in solid fuel boilers. Research methods. Analytical studies on the relevance of the use of energy culture of miscanthus as biomass for burning in solid fuel boilers were carried out by processing the available scientific and informational reports. Research results. For the production of biomass, special energy crops are used, which are characterized by rapid growth of technological mass - willow, poplar, sycamore, or certain varieties of herbaceous plants (miscanthus, millet, sorghum, etc.). Energy crops are plants that are specially grown for use directly as fuel or for biofuel production. After a single planting, the crop (miscanthus) can be harvested annually for 15 years or more with an average yield of 10 t/ha. Miscanthus has a well-developed root system (2,5 m deep), is characterized by rapid growth and resistance to low temperatures. Technological options for biomass combustion are divided into three main types: combustion in a layer, dust combustion, combustion in a pseudo-liquefied state, as well as a combined type - combined combustion of biomass with other fuels. Miscanthus is characterized by a fairly high level of energy production, and actually 143-560 GJ/ha, energy yield is 360 GJ/ha/year. Increasing the use of perennial energy crops such as miscanthus helps reduce fossil fuel consumption. In addition to high yields, drought resistance, maintaining soil structure, reducing the risk of soil erosion, improving soil organic matter and other important agronomic indicators, miscanthus has a high resource energy efficiency, which can be 90 %, a high level of conversion. With a yield of 8-17 t/ha/year, the selling price of miscanthus during its processing into thermal energy and biological oil of rapid pyrolysis was received at almost the same level - 100 €/t. The calorific value of energy culture is 17,7 MJ/kg, according to other scientific data is in the range of 16,0-17,2 MJ/kg, according to regulatory requirements CEN / TC 14961: 2005 – 18,4 MJ/kg, despite some deviations from the standards, miscanthus can be described as a valuable energy raw material suitable for combustion in boilers. Conclusions. According to the results of analytical studies, the relevance of using miscanthus energy culture as biomass for combustion in solid fuel boilers was assessed for the first time. Energy crops (miscanthus) after a single planting can be harvested annually for 15 years or more. Miscanthus is characterized by a high level of energy production, namely 143-560 GJ/ha, energy yield is 360 GJ/ha/year. Increasing the use of perennial energy crops such as miscanthus helps reduce fossil fuel consumption.

利用芒草作为生物质在固体燃料锅炉中燃烧的相关性
本研究的目的是评估将芒草能源培养物作为生物质在固体燃料锅炉中燃烧的相关性。研究方法。通过处理现有的科学和信息报告,对芒属植物作为生物质在固体燃料锅炉中燃烧的相关性进行了分析研究。研究结果。为了生产生物质,使用了特殊的能源作物,其特征是技术群体的快速生长——柳树、白杨、悬铃木或某些草本植物品种(芒草、小米、高粱等)。能源作物是专门种植的直接用作燃料或生活燃料生产的植物。一次种植后,这种作物(芒草)每年可收获15年或更长时间,平均产量为10吨/公顷。芒属植物根系发达(2.5米深),生长迅速,耐低温。生物质燃烧的技术选择分为三种主要类型:分层燃烧、粉尘燃烧、准液化状态燃烧,以及生物质与其他燃料的组合燃烧。芒的特点是能源生产水平相当高,实际产量为143-560 GJ/公顷,能源产量为360 GJ/公顷/年。增加使用芒草等多年生能源作物有助于减少化石燃料消耗。除了高产、抗旱、保持土壤结构、降低土壤侵蚀风险、改善土壤有机质等重要农艺指标外,芒属植物具有较高的资源能效,可达到90%,转化率较高。芒草产量为8-17吨/公顷/年,在其加工成热能和快速热解生物油的过程中,其售价几乎相同——100欧元/吨。能量培养的热值为17,7 MJ/kg,根据其他科学数据,在16,0-17,2 MJ/kg的范围内,根据CEN/TC 14961:2005-18.4 MJ/kg的监管要求,尽管与标准存在一些偏差,但芒草可以被描述为一种适合在锅炉中燃烧的有价值的能量原材料。结论。根据分析研究的结果,首次评估了利用芒草能源培养物作为生物质在固体燃料锅炉中燃烧的相关性。一次种植后的能源作物(芒草)每年可以收获15年或更长时间。芒的特点是高水平的能源生产,即143-560 GJ/公顷,能源产量为360 GJ/公顷/年。增加使用芒草等多年生能源作物有助于减少化石燃料消耗。芒属植物具有较高的资源能效,可达到75-90%,转化率较高。根据科学报告,根据CEN/TC 14961:2005–18,4 MJ/kg的监管要求,能源作物(芒草)的热值为17,7 MJ/kg,尽管与标准存在一些偏差,但芒草被认为是一种在固体燃料锅炉燃烧过程中有效的有价值的能源原材料。关键词:生物质,可再生能源,能源效率,能源作物,芒草,固体燃料锅炉。
