中浓度煤浆和高浓度水煤浆的特性分析与比较

Analysis and Comparison of Characteristics of Coal Water Slurry and Coal Slurry Used in Pipeline Transportation

中浓度煤浆适用于长距离管道输送,高浓度水煤浆适用于煤气化或锅炉用户使用,因用途不同它们的指标要求也不同。文章从煤浆浓度、粒度分布、流动性和稳定性等主要指标对中浓度煤浆和水煤浆进行了比较,提出了采用中浓度煤浆管道输送、运至用户后再制备成水煤浆供用户使用的模式,可以扬长避短,充分发挥各自的优势。

Medium concentrated coal slurry for long-distance pipeline transportation, coal water slurry for coal gasification or boiler users, because of their different purposes lead to their different indicators of the requirements are different. The paper compares the medium concentrated coal slurry and coal water slurry with the coal slurry concentration, the particle size distribution, the fluidity and the stability and so on. The paper puts forward the mode of using medium concentrated coal slurry pipeline to transport to the user and then preparing it into coal water slurry for users to use, which can avoid weakness and give full play to their respective advantages.
