Final Evaluation of the Research Project on Gasification of High Ash Fusion Temperature Coal Varieties from Kailuan
Thread Content
On September 6, 2015, it was reported that the project \"Study and Application of Gasification Characteristics of Coals with High Ash Fusion Temperatures\", carried out in collaboration between Kailuan Group, Anhui University of Science and Technology, and Monash University in Australia, passed the expert evaluation organized by the Hebei Province Science and Technology Achievement Transformation Service Center. By blending coal, coking dust, composite fluxes, lignite semi-coke, and coal with high ash fusion points, this project successfully achieved the goal of reducing the ash fusion point and improving the melting properties of coal with high ash fusion points; the results obtained at this stage are at an internationally advanced level.
I am quite interested in composite fluxes. It is one thing to be able to lower the ash fusion point of high-melting-point coal, but whether economic considerations can be taken into account in actual production is another matter. It is also uneconomical to add too much ash while reducing the ash fusion point.
Anhui University of Science and Technology, Professor Li Hanxu?
A factory has been using high-ash-melting-point slack coal from Shanxi Lu’an (>1500°C) on a large scale for pulverized coal gasification for 3 years now. Fluxes are limestone and low ash fusion point bituminous coal.
