Description
実際の石炭混焼ボイラでの燃焼灰の付着結果と膠着度とを比較し、実際の石炭混焼ボイラにて灰障害を招くことのない膠着度の付着安全域を特定し、該付着安全域内に膠着度が収まるようにバイオマスの添加率を調整する一方、
石炭に対するバイオマスの添加率を変えた複数の試験灰について膠着度を求め、該膠着度が付着安全域内で最大値をとるバイオマスの添加率を最適添加率として評価することを特徴とするものである。
・温度 :1000~1300℃
・雰囲気 :空気
・加熱時間:1h
・評価方法:下記式(1)で求められる数値を膠着度と定義して焼結性を定量化する(膠着度が1.0に近いほど硬く焼結していることになる)。
膠着度=ラトラ試験後の重量/ラトラ試験前の重量…(1)
Rf=(Base/Acid)×Na2O…(2)
Rs=(Base/Acid)×燃料中S…(3)

- バイオマスを再生可能エネルギーとして利用する石炭混焼ボイラで主燃料となる石炭にバイオマスを所定の添加率で混合した試料を灰化して試験灰を調製し、該試験灰を前記石炭混焼ボイラの燃焼温度条件で焼結させて焼結灰を生成し、該焼結灰をラトラ試験機にかけて試験前の焼結灰の重量で試験後の焼結灰の重量を割った比から膠着度を求め、該膠着度に基づき前記石炭混焼ボイラにおける燃焼灰の付着状況を事前に評価する石炭混焼ボイラにおける燃焼灰の付着予測評価方法であって、
実際の石炭混焼ボイラでの燃焼灰の付着結果と膠着度とを比較し、実際の石炭混焼ボイラにて灰障害を招くことのない膠着度の付着安全域を特定し、該付着安全域内に膠着度が収まるようにバイオマスの添加率を調整する一方、
石炭に対するバイオマスの添加率を変えた複数の試験灰について膠着度を求め、該膠着度が付着安全域内で最大値をとるバイオマスの添加率を最適添加率として評価することを特徴とする石炭混焼ボイラにおける燃焼灰の付着予測評価方法。 - 膠着度が0.5以下の領域を付着安全域として特定することを特徴とする請求項1に記載の石炭混焼ボイラにおける燃焼灰の付着予測評価方法。
