Summary• GE has considerable operational experience using low

calorific fuel gas for both steel mill and IGCC applications

• Blending of available mill fuel gas must be considered to meet minimum fuel heating value constraints

• Mill fuel gas must be extensively cleaned…removing particulate and tars to comply with turbine fuel specification requirements

• GT fuel control systems with load turndown, co-firing, and automation response capability provide flexibility with variable mill operations

• GE Gas turbine/combined cycle plants can be successfully utilized with ultra low heating value steel mill fuels
