Brief summary: What substances are components of ash? What is the impact of ash content on gasification? Answer: The ash composition includes Fe2O3, CaO, MgO, NaO, K2O, SiO2, Al2O3, and TiO2. Ash is an unnecessary and harmful substance in the gasification reaction; it does not participate in chemical reactions nor does it contribute to the formation of the useful components of syngas, and it reduces the cold gas yield ； Melting the ash requires heat, which increases the specific oxygen consumption and specific coal consumption ； Slag will erode and corrode the bricks on the fire-facing side of the gasification furnace, reducing the service life of these refractory bricks ； It increases the system’s thermal load, and a high ash content raises the water-to-gas ratio in the syngas, affecting subsequent processes ； It increases the load on the ash treatment system, deteriorates the water quality of the system, and easily causes blockages in pipes and valves.
