Description
廃材A、製紙スラッジB及び塊状ダストCが混在しており、該塊状ダストCが、該廃材Aを原材料とした廃材砕片由来のダストをスラッジにて塊状に形成させたものである主原料Dを、非酸化性雰囲気下で熱分解し、発生した熱分解ガスをスチームと反応させることを特徴とする、ガス化方法
に関する。
本発明のガス化方法では、原料として、廃材Aと製紙スラッジBと塊状ダストCとを混在させた主原料Dを用い、該主原料Dを非酸化性雰囲気下で熱分解し、発生した熱分解ガスをスチームと反応させる。
以下に示す廃材A、製紙スラッジB及び塊状ダストCを、以下の表1に示す組み合わせで混在させ、混合原料(主原料D)を準備した。該主原料Dを、ガス化装置内のアップドラフトガス化炉(炉下部層から上部層に向けて、灰化層、チャー層、揮発・熱分解層及び未反応原料層からなる4層の反応層を備えたガス化炉)に供給し、水蒸気と空気との混合気体雰囲気下で熱分解し、熱分解ガスを発生させた。なお、かかる熱分解の際、点火時にはプロパンガスを使用し、その後は廃材Aが自燃して熱分解が進行した。
