Abstract
Винахід стосується системи енергетичної оптимізації установки (3) для одержання металів прямим відновленням руд, зокрема заліза прямого відновлення, причому установка (3) включає щонайменше один відновний реактор (12), один пристрій (7, 7а, 7b) для розділення газових сумішей із сполученим нагнітальним пристроєм (4, 4а, 4b), а також приєднаний вище по потоку відносно відновного реактора (12) газонагрівальний пристрій (10). Крім того, частина технологічного газу (2, 2а, 2b) через підвідний трубопровід може бути підведена в установку (3) для одержання металів прямим відновленням руд щонайменше з однієї установки (1, 1а, 1b) для виплавки чавуну, зокрема установки для відновної плавки. У відповідній винаходу системі турбіна (8, 8а, 8b), зокрема турбодетандер, таким чином розміщена між пристроєм (7, 7а, 7b) для розділення газових сумішей і приєднаним вище по потоку відносно відновного реактора (12) газонагрівальним пристроєм (10), що перепад тиску між пристроєм (7, 7а, 7b) для розділення газових сумішей і відновним реактором (12) може бути перетворений у форму енергії, придатну для використання у приводі інших компонентів (4, 4а, 4b, 15, 15а, 15b) установки (3) для одержання металів прямим відновленням руд, зокрема в електричну і/або механічну енергію. За допомогою винаходу простим і сприятливим шляхом знижується вживання енергії установкою (3), і тим самим скорочуються експлуатаційні витрати, оскільки застосовуванням турбіни (8, 8а, 8b) економічно використовується перепад тиску між пристроєм (7, 7а, 7b) для розділення газових сумішей і відновним реактором (12).
