Authors: H. Pawlak-Kruczek and Team

Towards high efficiency power production the design of a supercritical combustion chamber for combusting H2 and methanol in sCO2 and sXe at extremely high pressure (above 200 bars)

The study utilizes experimental measurements and numerical analysis. The modeling will serve as an initial assessment of the combustor and inlet of fuels and oxidizer configurations to ensure full mixing and stable combustion. Results from modelling are validated by experimental work in combustor designed using numerical modelling results especially for development cooling system reactor.

The main objective is to develop and validate a closed-loop efficient renewable energy system based on a semi-open directly fired supercritical gas turbine engine operating on different fuels (e.g., hydrogen, methanol, and methane) with net-zero greenhouse gas emissions. The issues of high-pressure oxy combustion especially above supercritical conditions of both fuel and oxidizer (O2+CO2 or Xe0) require evaluation of real kinetics of combustion of H2 at high pressure at high concentration of CO2. Also, the research focuses on developing optimal conditions for stable oxy-combustion of methanol in a supercritical CO2 or xenon atmosphere. To investigate these topics – problems utilize experiments and numerical modeling. The modeling serves as an initial assessment of the combustor and inlet of fuels and oxidizer configurations to ensure full mixing and stable combustion. Results from modeling are validated by experimental work in combustors designed using numerical modeling results, especially for the development of cooling system reactors. The goal will be to find the optimum operating conditions, such as stable ignition of hydrogen, by providing sufficiently high adiabatic temperatures, effective mixing of hydrogen with oxidant i.e. design of optimal injection system gas fuel and oxidizer differing significantly in density, and effective cooling of combustion chamber walls with cooling sCO2.The goal will be to find the optimum operating conditions, such as the method of stable ignition of hydrogen, effective mixing of hydrogen with oxidant, and effective cooling of combustion chamber walls with cooling sCO2. Also, the studies on the integration of the Allam cycle with various industrial processes are performed, as well as the improvement options of the Allam cycle studied.
