The chemically recuperated gas turbine cycle testing platform was designed and built based on theoretical research and experimental study, which included the dual-stage flash evaporation, the diesel steam reformer, and the dual-fuel combustion system. In this paper, an experimental study on the oil (C7H16) prereforming performance is analyzed and the relative increment of the equivalent calorific value is 46.2%. Combustion characteristics are calculated with oil and reformed gas and the results show that main combustion zone temperature drops from 2280 to 1910 K, which leads the ultra-low NO emissions of 1.8 ppm. The flame is stable using reformed gas and the wall temperature is low, but the nonuniformity of outlet is relatively high. Thermal efficiency of combustion is more than 99% even at low load condition.
