文摘

Effect of coal blending on ash sintering and fusion was systematically studied. Blending ZL with AB and IL increased the ash sintering temperature. AFTs decreased first and then increased as the AB or IL blending ratio increased. Lower ashing temperature resulted in lower ash sintering and fusion temperatures. Mineralogical and morphological changes during sintering and fusion explained.
