Abstract

Invenţia se referă la un procedeu şi la o instalaţie de reducere a conţinutului de N0dintr-un gaz de evacuare, provenit, în special, de la arderea combustibilului în instalaţiile de încălzire. Procedeul conform invenţiei cuprinde prepararea unei emulsii Pîn lichid apos, injectarea unei cantităţi în gazul de evacuare şi îndepărtarea dioxidului de azot din gazul de evacuare, la o anumită distanţă în aval faţă de poziţia prestabilită, care este astfel aleasă, încât oxidarea accelerată, în prezenţa fosforului, a oxidului de azot din gazele de evacuare să se încheie înainte de evacuarea dioxidului de azot. Instalaţia pentru aplicarea procedeului, conform invenţiei, cuprinde o baie (18) de apă încălzită, pentru topirea fosforului înmagazinat într-un container (12), emulsia formatăfiind preluată într-un rezervor (34) etanş, precum şi nişte mijloace pentru transportul fosforului lichid din container (12) în rezervor (34) şi mijloace pentru omogenizarea amestecului fosforului lichid cu apa, în rezervor (34).
