Abstract
Description
本発明の基本的な概念は、ひとつの大きなものに代えて、いくつかの小さい部分の炉を採用することにより、全システムの効率を改良する。これらは小さなモジュール炉は非常の狭い範囲の製品流速で動作するように、熱的に(熱損失および熱の一様性に関して)最適化される。需要が減少すると、個々のモジュー組立体22はパワーを保存するために、低温スタンバイモードに切り換えられる。モジュール炉エンクロージャー110の一実施例が図3に示されている。この炉エンクロージャー110は互いに独立して動作可能な三つの、加熱されるチェンバー112a、112b、112cを有する。
a.温度の一様性および制御:セラミック酸素発生要素を含むエンクロージャーがより大きくなり、複数のモジュラーを含み、エンクロージャー内の温度勾配は大きくなり、制御が難しくなる。いくつかの小さなエンクロージャーを含むようにすると、より正確な制御およびより一様な温度が可能となる。
b.耐故障性:オーブン要素の機能不全の場合、機能不全を含むモジュールが停止しても、他のモジュールは作動している。他のモジュールは、ひとつのモジュールの停止を補償するために、標準モードで動作することもより高い出力モードで動作することもできる。
c.低流動での改良された効率:断熱されたエンクロージャーの壁部を通過する熱の伝導は電力消費の主要な点である。ピークフローの一部が必要である場合、ひとつのエンクロージャー装置に対して全システムの熱損失を減少させるために、ひとつ以上のオーブンモジュールを停止させることができる。
1. 制御の複雑さが増す。
2. システムの大きさ、重量が増す。
3. モジュラー炉が準備中、または停止しているとき、システムの応答時間が長くなる。
