Abstract

Mevcut tarifname, oksijenli yakıtın, sirkülasyonlu bir akışkan yatak üzerinde yanması için gazın dağıtılmasına yönelik bir yöntem sağlar. Yöntemde gaz, sirkülasyonlu akışkan yatağın bir fırınına üç fazda sağlanmakta olup, yöntem, fırının dibinden, oksijen ve geri dönüştürülmüş baca gazı içeren birinci fazdaki bir gazın üflenmesini; yoğun faz bölgesi ile fırının seyreltik faz bölgesi arasındaki bir geçiş bölgesinden, geri dönüşümlü baca gazı içeren ikinci faz bir gazın üflenmesini; ve fırının bir yan duvarından, oksijen içeren üçüncü faz bir gazın üflenmesini içermektedir. Mevcut tarifname, sirkülasyonlu akışkan yatağın fırınında yüksek oksijen konsantrasyonunda sabit yanma gerçekleştirir, böylece, yüksek oksijen konsantrasyonunun neden olduğu lokalize yüksek sıcaklık probleminden kaçınır ve bir oksijen ve yüksek oksijen konsantrasyonuna sahip geri dönüştürülmüş baca gazı karışımının taşınmasına yönelik olan güvenlik problemini çözer.
