Abstract

Представлен способ очистки в рабочем режиме труб в теплообменнике. Способ включает добавление абразивного материала в охлаждаемый газовый поток и абразивное удаление любых частиц или катализаторной пыли, которые прилипли к стенкам трубы. Абразивный материал должен быть твердым водорастворимым веществом, чтобы позволить осуществить удаление абразивного материала в башенном охладителе.
