Externally fired gas turbine technology: A review

Al-attab, K.A.; Zainal, Z.A. - In: Applied Energy 138 (2015) C, pp. 474-487

Externally fired heat engines were used widely since helium the industrial revolution using dirty solid fuels for example coal, due to the lack of refined fuels. However, with the availability of clean fuels, external firing mode was abandoned, except for steam power plants. Lately, with the...
