Influene of coal type on evolution characterisitcs of alkali metal compounds in coal ocmbustion

摘要

The influence of coal type on the evoluation characteirsitcs of alkali metla compounds.esepcially sodium ocmpounds.on the supposition of pressureized fluidized0bed ocmbustion was eluciadated experimentally in this sutyd by using a radpidly heated electricla batch reactor.The evolution fraction of soldium was evaluated quantitatively by analyzing the sodium content in the burnt particles.Water and ammonium acetate extractions were carried out to classify the form of sodium ocmpounds in the raw coals,and the ion components in the water-extreacted solution were also analyzed by ion chromatogrsphy.
