Description
(1) 木質系バイオマス粉砕物の水分を8〜50%に調整し、嵩密度が0.55g/cm3以上になるまで高密度化した後、酸素濃度10%以下かつ温度170〜350℃の条件下で焙焼することを含む、固体燃料の製造方法。

(3) 固体燃料のハードグローブ粉砕性指数が30〜70である、(1)または(2)に記載の方法。
(4) 200〜330℃で焙焼する、(1)〜(3)のいずれかに記載の方法。
(5) 木質系バイオマス粉砕物の水分を8〜30%に調整する、(1)〜(4)のいずれかに記載の方法。
(6) 固体燃料が、石炭と混燃させるための固体燃料である、(1)〜(5)のいずれかに記載の方法。
(7) 木質系バイオマス粉砕物の水分を8〜50%に調整し、嵩密度が0.55g/cm3以上になるまで高密度化した後、酸素濃度10%以下かつ温度170〜350℃の条件下で焙焼することよって得られる固体燃料。
(8) 物質収率が60〜90%、熱量収率が70〜95%、ハードグローブ粉砕性指数(HGI)が30〜70である、木質バイオマスを焙焼させて得られる固体燃料。
杉の樹皮をナイフ切削型バイオマス燃料用チッパー(緑産社製、Wood Hacker MEGA360DL)にて粉砕処理した。樹皮粉砕物を70mmのスクリーンに通した後、乾燥機で120℃、10分間乾燥処理を行って、水分を12%に調整した。
製材のサンダーダスト(粉砕物のサイズ:約7mm以下)を原料として、水分を10%に調整した。次いで、実施例1と同様にして高密度化処理を行って、嵩密度0.69g/cm3のペレットを得た。続いてこのペレットを原料として、実施例1と同様にして焙焼を行って固体燃料を得た。
製材断裁シュレッダーダスト(粉砕物のサイズ:約7mm以下)を原料として、水分を10%に調整した。次いで、実施例1と同様にして高密度化処理を行って、嵩密度0.68g/cm3のペレットを得た。続いてこのペレットを原料として、実施例1と同様にして焙焼を行って固体燃料を得た。
製材プレーナ粉(粉砕物のサイズ:約5mm以下)を原料として、水分を10%に調整した。次いで、実施例1と同様にして高密度化処理を行って、嵩密度0.69g/cm3のペレットを得た。続いてこのペレットを原料として、実施例1と同様にして焙焼を行って固体燃料を得た。
杉の樹皮をハンマーミル(Prrsident Husky Corporetion製、PROGRIND 1500T)にて粉砕処理した。樹皮粉砕物(水分含量:約55%)を100mmのスクリーンに通した後、水分調整を行わずに実施例1と同様にして高密度化処理を行ったが上手く成型できず、嵩密度0.078g/cm3の粉体が得られた。
実施例1および比較例1で用いた杉の樹皮(未粉砕)を、比較例2の固体燃料試料とした。
実施例1〜4、比較例2で得られた固体燃料について、下記の項目を評価した。結果を表1に示す。
・物質収率:焙焼前後の試料の重量から計算した。
・熱量収率:焙焼前後の試料を島津燃研式自動ボンベ熱量計CA-4PJにて測定した発熱量から計算した。
・粉砕性:試料をボールミルで200rpm、4分間粉砕し、200メッシュをパスしたものの重量を測定し、粉砕性を評価した。石炭の粉砕性の指標であるハードグローブ粉砕性指数(HGI、JIS M 8801:2004)の値から換算して、固体燃料試料のHGIとした。なお、HGIが小さいほど、試料が粉砕しにくいことを意味する。
