Abstract

Винахід стосується способу одержання відновлювального газу для відновлення залізної руди шляхом охолодження і сухого знепилення генераторного газу (20), отриманого у плавильному газифікаторі (3) для виготовлення чавуну, а також пристрою для здійснення способу. При цьому генераторний газ (20) після його виведення з плавильного газифікатора (20) і перед його сухим знепиленням охолоджують як вприскуванням води, так і теплообміном.The invention relates to a method for producing a reducing gas for the recovery of iron ore by cooling and dry dusting off the generator gas (20) obtained in the smelter (3) for the production of pig iron, as well as a device for carrying out the method. In this case, the gas (20) after its removal from the melting gasifier (20) and before its dry dusting is cooled by both water injection and heat exchange.
