Specifically, in the flow heating test, the mass of the fluid medium collected by the cyclone 88 is measured. Then, the difference between the mass of the fluid medium filled in the core tube 81 at the start of the test and the mass of the fluid medium collected by the cyclone 88 is divided by the mass of the fluid medium filled in the core tube 81 at the start of the test, The value obtained by multiplying this by 100 is taken as the residual rate [%].

ここで、流動媒体4の凝集抑制効果を評価するための、流動加熱試験について説明する。
(1)11.5gの模擬灰(K2CO3)を測り取り、流動層2中の模擬灰体積濃度が0.117g/mLとなるように、ビーカー内で流動媒体の試料と模擬灰とを混合する。
(2)炉心管81に、初期静止層高が60mmとなるように、試料と模擬灰との混合物を充填する。
(3)2.0NL/minのArガスで通気しながら、管状炉80で炉心管81を昇温させる。流動層2内の温度が750℃付近になれば、Arガスの流量をU/Umf=5.0相当となるように調整する。
(4)流動層2内の温度が750℃に安定してから、ArガスにPRガス(CH4 10%+ArベースのProportional Gas)を添加することにより、CH4濃度が4%となるように調整して、試験を開始する。
(5)流動媒体が凝集して流動しなくなると、流動層差圧ΔP1が低下する。そこで、流動層差圧ΔP1の変化を波形チャートに基づいて観察し、流動層差圧ΔP1が急激に減少した時点で試験を終了する。流動層差圧ΔP1の急激な変化が観察されない場合には、5時間で試験を終了する。
(6)試験終了後、炉心管81を降温し、炉心管81内の状況(凝集物生成によるブリッジ、管内付着状況等)を確認する。更に、炉心管81の内容物を取り出し、目開き500μmの篩を用いて、分級後の各重量を測定する。
流動媒体4は、所定の耐久性を備えることが好ましい。流動媒体4の耐久性は、流動加熱後の残留率で評価することができる。耐久性の評価の基準は、例えば、一般的に流動媒体として使用されてきた珪砂の耐久性としてよい。
