In order to improve the thermal efficiency of gas turbine

an idea of effective combination of chemically recuperation (CR) with continuously rotating detonation pressurized combustion (CRDPC) was put forward. The effects of different forms of methane steam reforming on the heat recovery

the characteristics of pressurized combustion flow field and combustion performance of reformed gas were separately investigated through experimental and numerical researches. Results show that synergistic catalytic reforming has the best performance

with methane conversion rate of 46.51% and total enthalpy increase rate of 25.28%; the difference of reformed gas components has little effect on the detonation wave flow structure

but the increase of H2 mass fraction can improve the detonation wave propagation speed

and will intensify the precombustion in the contact discontinuity between fresh mixed gas and detonation products from the previous wave; under the premise of the same total pressure and stoichiometric ratio

when H2 mass fraction increases by about 1.1%

the inlet mass flow rate of premixed gasdecreases by about 4.5%

but the pressurized ratio of CRDPC decreases by about 6.0%

mainly due to the precombustion at the contact discontinuity.
