摘要

随着以碳氢化合物为基础的燃料价格的上涨,为采矿和石油生产工业的机器寻找和使用替代类型的燃料是非常相关的。大多数现有的替代燃料本身不能被认为是现成的汽车燃料。解决这个问题的方法之一是将它们与商业燃料按一定比例混合使用。本工作涉及以柴油和大豆油为基础的混合燃料的混合器的主要特性的开发和研究,以及所获得的不同体积比的柴油和大豆油混合物的物理和操作特性的研究结果。从柴油和大豆油中获得混合替代燃料的过程是在由混合器(其设计受乌克兰专利保护)和齿轮泵组成的开发装置上实现的。作为装置一部分的混合器特性研究表明,在替代燃料组件温度为20°С,混合器全压损失Δр≈(60-65)kPa时,大豆油的体积消耗达到10.7.10-6 m3/s。大豆油含量为10%的195升混合燃料的制备时间为30 ~ 33分钟。研究表明,将大豆油与柴油以5-50%的体积混合,可以改善粘温特性,并且可以在不改变供电系统设计和燃料设备调节的情况下在柴油发动机中使用这种混合物,这表明大豆油是一种有前途的柴油燃料添加剂,可以改善其技术和运行性能。

Technology of Obtaining Mixed Alternative Fuel Based on Organic Substances for Mining Technological Transport Engines
Abstract In connection with the increase in the price of fuel based on hydrocarbons, the search and use of alternative types of fuel for machines in the mining and oil production industry is quite relevant today. Most of the existing alternative fuels by themselves cannot be considered as ready-to-use motor fuels. One of the ways to solve this problem is to use their mixtures with commercial fuels in certain ratios. This work deals with the development and research of the main characteristics of the mixer for obtaining mixed fuels based on diesel fuel and soybean oil, as well as the results of the study of the physical and operational properties of the obtained mixtures of different volume ratios of diesel fuel and soybean oil. The process of obtaining a mixed alternative fuel based on diesel fuel and soybean oil was implemented on a developed installation consisting of a mixer, the design of which is protected by a patent of Ukraine, and a gear pump. The study of the characteristics of the mixer as part of the installation showed that at a temperature of the components of the alternative fuel of 20°С, with a loss of full pressure on the mixer Δр ≈ (60-65) kPa, the volume consumption of soybean oil reached 10.7.10-6 m3/s. The time of preparation of the fuel mixture in the amount of 195 liters with a content of soybean oil of 10% ranged from 30 to 33 minutes. As research has shown, mixing soybean oil with diesel fuel in the amount of 5-50% vol. provides an improvement in viscosity-temperature properties and makes it possible to use such mixtures in diesel engines without changes in the design of the power supply system and regulation of fuel equipment, which characterizes soybean oil as a promising additive to diesel fuels to improve their technical and operational performance.
