Study on how the main oxides affected the Baori lignite ash fusion temperature
YUAN Jian
Abstract：Regarding to the main oxides component in coal ash, the mixture was done according to different ratios, then, the simulation of ash samples which was quite similar with the raw coal at ash fusibility were prepared, in a weak reductive atmosphere, determination of fusion characteristic temperature for simulated ash samples was done, meanwhile, how each oxides affected the ash fusion temperature was analyzed, it was indicated that in the process of adjusting the Baori lignite ash fusion temperature, SiO 2 、 Al2 O 3 have functions of increase and reducing at the same time, Fe2 O 3 、 Na2 O could be good fluxing agent, adding CaO had good resistance welding functions.
