What is the concentration of water coal slurry made from lignite?
Thread Content
It is said that lignite has poor pulping properties. Does “pulping properties” here refer to stability, or low concentration? Also, what is the typical concentration of water-coal slurry produced from lignite these days? Thank you all!
The concentration of water coal slurry produced from lignite is generally around 58%.
Reply to 2# GSP: Do you have any more specific information?
For Baori lignite, I’ve only managed 53%, while the semi-coke obtained from the pyrolysis of lignite can reach 60%
I’d like to ask this expert! Under what experimental conditions was this 58% concentration achieved?//////:handshake
I was wondering if, during the most intense pyrolysis phase, you followed the conditions and procedures described in the literature? ? ? :handshake
The typical pulping concentration for raw lignite is around 53%, while the pulping concentration for lignite semi-coke can reach 58%
It won’t exceed 60% for lignite raw coal; generally, that’s the figure. I hope specific conditions and industrial data can be provided – could anyone help with that?
There’s no such thing. The value for our brown coal gasification to form slurry is around 51; we’ve already achieved values of 48 as well
Sorry, it was a typo; it’s around 50. I typed it wrong.
It mainly depends on the internal moisture content of lignite; lignite with an internal moisture content above 10% has poor slurry-forming properties. I have conducted experiments on lignite’s slurry-forming capabilities, and those who are interested can contact me. By reducing the internal moisture content of lignite, its slurry-forming properties improve. Generally, when the internal moisture content is between 4–5%, the slurry-forming capacity is around 60%, with a semi-coke concentration of about 65%. Therefore, to use lignite for water coal slurry, it must first be upgraded in quality. . . . . . . . . . . . .
