1. Scientific and technical background for the development of coal-fired ultra-supercritical steam power plants.
The project aim: the
main components development for the energy boiler and steam turbine unit
ensuring the creation of highly efficient and reliable power plants with
ultra-supercritical steam parameters (pressure over 35 MPa; temperature over
720°C) with a gross efficiency about 50%.
The main results:
1.
a flow path of the ultra-supercritical steam turbine
has been developed
2.
a new horizontal layout of a pulverized coal-fired
energy boiler has been developed, which reduces the cost of the power plant by
decreasing the high-temperature steam pipes’ length.
2.

thermohydraulic models.
The project aim: the
development of the design solutions for blade cooling of the Russian gas
turbines with an initial temperature higher than 1300°С to ensure their reliable operation.
The main result: gas turbine
blade cooling system for the initial temperature of 1300°C was designed and
tested.
3. Research and development of the pipeline flow stabilizers.
The project aim: the development
of flow stabilization devices reducing the dynamic loads and vibrations in
piping systems for transporting water, air, and steam.
