Abstract

Реакторът намира приложение в енергетиката. При него проникването на вторично подавания въздух се увеличава чрез разделяне на разстоянието, необходимо на въздуха да проникне до приблизително половината от дълбочината на пещта, без физическо разделяне на корпуса на две части. Реакторът (10) с циркулиращ кипящ слой включва корпус (11), частично определен от челна (12) и задна (14) стена, свързани вдолната си част чрез дъно (16). В корпуса (11) са разположени средства за подаване на първичен въздух през дъното (16), средства за рециркулация на частиците в зоната на горене и едно или повече устройства (30) за нагнетяване на вторичен въздух, служещи за доставяне на вторичен въздух в циркулиращиякипящ слой над дъното (16), така че вторично подаваният въздух да достигне дълбоко в корпуса (11).Устройството (30) за нагнетяване на вторичен въздухе флуидно свързано със срещуположно поместени дюзи (31). Долната част (36) на устройството (30) е свързана чрез екрани от тръбни мембранни панели (32) със захранващ колектор (34), разположен под пода(17) на дъното (16), а горната част на устройството (30) е свързана чрез екрани от изходящи мембранни тръби (38) с изходящ колектор над покрива на пещта.
