REDUCTION METHOD OF UNBURNT CARBON IN COAL ASH
PROBLEM TO BE SOLVED: To provide a reduction method of unburnt carbon in coal ash for classifying and removing the unburnt carbon by a dry type fine particle classifier by freeing as a particulate of the unburnt carbon by effectively cracking an agglomerate of a particle of including such the unburnt carbon, since there is the problem of being unable to efficiently and sufficiently remove the unburnt carbon in a classification method by a conventional dry system, since the partially freed unburnt carbon and its agglomerate exist in the coal ash of including the unburnt carbon much, and further, since the unburnt carbon of existing by agglomerating and sticking mixedly exists in a fly ash particle that is a main component of the coal ash.SOLUTION: A reduction method of unburnt carbon in coal ash is used for classifying and removing the unburnt carbon in the coal ash by a dry type fine particle classifier, after cracking by a dry type mill by adding a specific organic additive by a predetermined quantity to the coal ash.SELECTED DRAWING: Figure 1
【課題】未燃炭素を多く含有する石炭灰には一部が遊離した未燃炭素や、その凝集体が存在する。更に石炭灰の主成分であるフライアッシュ粒子に凝集・付着して存在する未燃炭素が混在するため、従来の乾式による分級方法では未燃炭素を効率よく充分に除去できないという問題があった。かかる未燃炭素を含む粒子の凝集体を効果的に解砕して未燃炭素の微粒子として遊離させ、未燃炭素を乾式微粉分級機で分級して除去し、石炭灰中の未燃炭素の低減方法を提供する。【解決手段】特定の有機添加剤を石炭灰に所定量添加して乾式ミルで解砕した後、乾式微粉分級機で石炭灰中の未燃炭素を分級して除去することを特徴とする石炭灰中の未燃炭素の低減方法を用いた。【選択図】図１
