Steam plant based on high-speed active microturbine with valve-inductor generator as part of power engineering complex for processing of CURRENT and power plant for hydrogen production

Abstract

In the work, the possibility of using microturbine plants to cover auxiliary needs in the electric and thermal energy of complexes for the processing of municipal solid waste, as well as in hydrogen production plants when oxidizing powdered aluminum with water. There were proposed basic thermal diagrams of power units. There were given justification for the choice of wet-steam microturbines, which provide a higher ratio between thermal and electric power, as well as the possibility of their separate regulation in comparison with gas turbine and gas piston units. There were analyzed the working process of a single-stage two-stream active centripetal steam microturbine with an electric power of 50 kW (600 kW - thermal), which was developed, manufactured and tested, both at idle and under load as part of energy technology complexes for the disposal of municipal and agricultural solid waste. Tests showed a reduced blade efficiency of the radial microturbine compared to the calculated one. There were carried out analysis of possible causes of discrepancy and measures were developed to achieve the declared characteristics by subsequent samples of turbogenerators.
