德士古煤种及煤浆特性分析

Analysis about the Characters of Coal and Coal Slurry Process in the Texaco

德士古(Texaco)水煤浆加压气化技术主要原料为水煤浆,深入了解煤种及煤浆特性对气化工艺的影响,将有助于正确的选择气化工艺,指导生产平稳运行。介绍了煤种的主要特性和水煤浆的基本特性。指出灰分含量少、煤灰熔融温度低的原煤有利于气化炉稳定高效的运行;变质程度深、内水含量少的煤种则容易制成高浓度的水煤浆;性能好的水煤浆,要具有高浓度、低粘度、流动性好、稳定性好等特点,以适合贮运及气化。

Coal slurry is the main material in the Texaco coal gasification process,so doing researches to the characters of coal and coal slurry is helpful for choosing proper gasification process and instructing the running of the Texaco plant.To introduce the characters of coal and coal slurry.The coal with less ashes and lower ash melting point makes the Texaco gasifier more stable and efficient.While the coal with deeper transformation and less inner water makes it easier to produce coal slurry which with higher concentration.The high qualities of the coal slurry which should be high concentration,low viscosity,good floating and stable can make it suitable to be reserved,transported and gasified.
