A suppression method of PM2.5 formation using blended coals is discussed. The effects of blended coals containing low-melting point ash and those with a high value of the indicator (=(H/C)/(O/C)×VM×ASH) on PM2.5 formation were systematically extracted. In both cases, the amount of PM2.5 formation decreases with increasing blending ratio. The decrease results from the melting of the ash particles and their coalescing with high-melting-point ash, resulting in the formation of large particles. The decrease behavior results from the raw coals with a high value of indicator releasing the high-viscosity component, which binds the surrounding char particles (large lumps) and results in the intensity combustion and large ashes.
