This paper presents the results of experimental research into the component composition of gases and ash residue from the combustion of a set of high-potential coal-water slurries containing petrochemicals. We have established that the use of slurry fuels provides a decrease in the CO, CH, SO, and NO concentrations as compared to those from coal combustion. The content of carbon monoxide and hydrogen in the gas environment from the combustion of slurries is higher due to the intense water evaporation. It is shown that adding biomass allows a further 5-33% reduction in the emissions of nitrogen and sulfur oxides as compared to the coal-water slurry and the composition with added waste turbine oil and a 23-68% decrease as compared to coal (per unit mass of the fuel burnt). The mechanisms and stages of CO, SO, and NO formation are explained with a view to controlling gaseous anthropogenic emissions and ash buildup. The values of the relative environmental performance indicator are calculated for slurry fuels. It is shown to exceed the same indicator of bituminous coal by 28-56%.
本文介绍了一组含有石化产品的高潜能水煤浆燃烧时气体成分和灰渣组成的实验研究结果。我们已经确定，与煤燃烧相比，浆状燃料的使用会降低 CO、CH、SO 和 NO 的浓度。由于水的剧烈蒸发，浆状燃料燃烧时气体环境中的一氧化碳和氢气含量更高。研究表明，与水煤浆和添加废涡轮机油的混合物相比，添加生物质可使氮氧化物和硫氧化物的排放量进一步减少 5-33%，与煤相比减少 23-68%（按燃烧燃料的单位质量计）。解释了 CO、SO 和 NO 形成的机制和阶段，以控制人为气体排放和灰分积聚。计算了浆状燃料的相对环境绩效指标值，结果表明该值比烟煤高 28-56%。
