Title:
シャフト炉への熱ガス送り込み方法
Document Type and Number:
Japanese Patent JP5547799
Kind Code:
B2
Abstract:
The present invention proposes a method for feeding hot gas to a shaft furnace (12), wherein the method comprises feeding a first portion (32) of a first gas flow (24) to a mixing chamber (36) and feeding a second portion (34) of the first gas flow (24) into said shaft furnace. The method further comprises feeding a second gas flow (28) to the mixing chamber (36), allowing the first portion (32) of the first gas flow (24) to mix with the second gas flow (28) in the mixing chamber (36), thereby forming a third gas flow (38), and feeding the third gas flow (38) to the shaft furnace (12). The first gas flow (24) has a first volumetric fluid flow rate (V1), a first temperature (T1) and a first pressure (p1); the second gas flow (28) has a second volumetric fluid flow rate (V2), a second temperature (T2) and a second pressure (p2); and the third gas flow (38) has a third volumetric fluid flow rate (V3), a third temperature (T3) and a third pressure (p3). According to an important aspect of the present invention, the first temperature (T1) is higher than the second temperature (T2) and the first pressure (p1) is lower than the second pressure (p2) and the third temperature (T3) is regulated by controlling the second pressure (p2).
