The paper considers a model of combustion powdered energy-accumulating substances (EAS) in a cylindrical combustion chamber. This camera can be considered as a prechamber of the hydrogen reactor for transport and stationary power plants based on gas turbine engines. For calculations of combustion of powdered EAS in the flow of superheated steam a program is developed. Distribution of the temperature in the chamber axis at different values of the coefficient of oxidant excess (water vapor). The authors determined the size of the depth of the flame front at the given conditions of the combustion chamber with energy-accumulating substances.

The paper considers the results of mathematical modeling of strain state of a non-uniformly heated ceramic frame of rotary heat exchanger of multi-purpose gas turbine engine with the power of 300 kW . Received a conclusion that the implementation of frame heat exchanger made from ceramics will enable the design of the rotary heat exchanger with high degree of regeneration (95-97%), without increasing the amount of air leaks through the seals of the heat exchanger.
