The Varying characterization of Alkali Metals (Na, K) from coal during the Initial Stage of Coal Combustion

摘要

The first step in controlling alkali gaseous phase concentrations in flue gas in understanding their behavior during coal combustion. The behavior of sodium and potassium in coal during the initial stage of combustion was investigated. A series of tests were conducted under two combustion temperatures (800 deg.C and 900deg.C) and two atmospheres (21 vol /100 and 6.36 vol /100 O_2).
