There is insufficient literature about solarized gas turbines that achieved high efficiency and solar share simultaneously. It is because the outlet temperature of a solar receiver is always much lower than a combustor and it is difficult to design a high-efficiency exhaust-heat recovery system except for a complicated Rankine cycle. A solar-assisted chemically recuperated gas turbine system is proposed and expected to achieve a good performance by combining with two-stage fuel-steam reforming. The first stage is a low-temperature reformer, recovering exhaust gas heat, and the second stage is a high-temperature one, absorbing concentrated solar radiation. Thermodynamic analyses and comparisons are conducted. This system is expected to have a competitive thermal efficiency of 47.7%, which is 10.6 percentage points higher than that of a solarized gas turbine system without reformers. Meanwhile, it has a solar share of 75.0%, which is 12.8 percentage points higher than that of a solarized gas turbine system with a low-temperature reformer. In the viewpoint of energy level, the two-stage fuel reforming upgrades low-level thermal energy of the turbine exhaust and solar receiver into high-level chemical energy, reducing exergy destruction. The relative upgrade of energy level is 38.2% for turbine exhaust and 17.4% for solar thermal energy. (C) 2017 Elsevier Ltd. All rights reserved.
