摘要: The lignite boilers are designed for lower quality fuels, and often the ash is not utilized. This work assessed impact of combustion an herbaceous biomass with a low-quality Greek on resulting fly ash. Test results were compared those samples from industrial facility using same fuel qualities. Inductively coupled plasma-optical (ICP) emission spectroscopy, X-ray powder diffraction (XRD), scanning electron microscope (SEM) analyses performed collected samples. Despite significantly higher contents K, Na S in biomass, at 50% co-firing thermal share, major minor oxides comparable to quality. attributed high content lignite, low much heating value biomass. There improvements performance characteristics blend. initial setting time volume stability evaluations improved supports efforts good practices management, social responsibility, circular economy, power plant renewable energy operations, fuels plants.
