摘要

本文介绍了雪松针叶初始含水量对基于 D 级动力煤的水煤浆（CWS）着火时间特性影响的实验研究结果。生物质（落叶和新剪的雪松针叶）被用作加速点火过程的添加剂。分析了水煤浆成分中植物添加剂的初始水分含量对着火延迟时间的影响。结果表明，雪松针叶的初始含水量对燃料点火过程的时间特性没有显著影响（差异不超过 4%），但添加雪松针叶后，点火延迟时间显著缩短（煤水悬浮液的点火速度平均加快了 15%）。

Effect of the Initial Moisture Content of Cedar Needles on the Time Characteristics of the Ignition of Coal–Water Suspensions

The results of experimental studies on the influence of the initial moisture content of cedar needles on the time characteristics of ignition of coal–water suspensions (CWSs) based on D-grade thermal coal are presented. Biomass (fallen and freshly cut cedar needles) was used as an additive accelerating the ignition process. The effect of the initial moisture content of the plant additive in the composition of coal–water suspensions on the ignition delay times was analyzed. It has been established that the initial moisture content of cedar needles did not have a significant effect on the time characteristics of the fuel ignition process (the difference did not exceed 4%), but the addition of the needles led to a significant decrease in the ignition delay times (the CWS ignited faster on average by 15%).

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
