Abstract

The invention relates to a gas turbine exhaust as hot blast for a blast furnace. In certain exemplary embodiments, a system includes a gas turbine system 12 having a turbine 16, combustor 18, and a compressor 20. The system also includes an output flow path from the gas turbine system 12. The system further includes a blast furnace 80 coupled to the output flow path, wherein output flow path is configured to deliver heated air 102 or exhaust gas 34 from the gas turbine system 12 directly to the blast furnace 80 as a blast heat source.

Description

technical field [0001] The subject matter disclosed herein relates to blast furnaces, and more particularly, to systems and methods for using exhaust and hot extracted air from a gas turbine as hot blast for a blast furnace. Background technique [0002] Blast furnaces are commonly used, for example, in rolling mills to produce metallic iron. Hot blast, such as air heated to very high temperatures, is used in the blast furnace to reduce iron oxide to metallic iron. The hot blast is typically generated by stoves that heat the air before introducing the hot blast into the blast furnace. However, hot blast stoves have a tendency to foul up over time. Contents of the invention [0003] Certain embodiments commensurate with the scope of the initially claimed invention are outlined below. These embodiments are not intended to limit the scope of the claimed invention, but rather these embodiments are intended only to provide a brief summary of possible forms of the invention. ...
