Research on the Modification of E-class Gas Turbine Blended with Hydrogen-rich Synthesis Gas

A study was conducted on the modification of SGT5-2000E gas turbine by blending natural gas fuel with hydrogen rich synthesis gas. The blending ability of hydrogen-rich synthesis gas in this type of gas turbine was analyzed, and modification measures were proposed to address technical issues caused by H₂ and CO in hydrogen-rich synthesis gas. The performance parameters of the gas turbine unit before and after blending were compared. Results show that this type of gas turbine can mix up to volume fraction of 50% hydrogen rich synthesis gas. When blending 50% hydrogen rich synthesis gas, the performance parameters of the gas turbine meet the design requirements, and the relevant modifications and improvement measures have achieved the expected results, improving the operational flexibility of this type of gas turbine unit and providing reference for similar blending research.
