Description
Изобретение относитс к способу обработки топлива, в частности к способу хиьтческой обработки топлива , и может быть использован в топливо сжигающих установках.
Целью изобретени вл етс повышение экономичности путем снижени недожога.
На чертеже изображена установка дл осуществлени способа химической обработки топлива.
Установка содержит камеру 1 сгор ни , нижн часть которой снабжена патрубком 2 дл подачи топлива и, в случае необходимости, св зывающего серу агента, патрубком 3 дл подачи кислородсодержащего газа, например воздуха, перфорированным распределительна элементом 4, а также патрубком 5 дп подачи мелкозернистого компонента 6 и крупнозернистого компонента 7. При этом в патрубок 5 входит обозначенный стрелкой 8 другой патрубок дл подачи воздуха. Камера I сгорани соединена с циклонным сепаратором 9 через трубопровод }0, установленный в ее верхней части, и трубопровод П с размещенным в нем шаровым KJtaПорошковый известн к,

В сепараторе 9 частицы мелкозернистого компонента отдел ют от поступающего по трубопроводу 10 газового потока и рециркулируют в камеру 1 сгорани через трубопровод 1I. Нижн часть сепаратора 9 снабжена
емкостью 13 дл сбора мелкозернистых частиц, имеющей смотровое стекло 14 и трубопровод 15 дл отвода в емкость 16 золы, попадающей вместе с мелкозернистыми частицами в еьгкость 13. Удаление золы осуществл ют путем подачи воздуха в емкость 13 в направлении стрелки 17. Рециркул ции мелкозернистых частиц в камеру 1 сгорани способствует подача воздуха
и трубопровод 11 в направлении стрелки 18. Циклонный сепаратор 9 снабжен патрубком 19 дл отвода очищенного газового потока на дальнейшую переработку и утилизацию. В камере 1
сгорани размещен бойлер 20.
