STUDY OF A SMALL STEAM TURBINE AT LOW PRESSURE USING A PERMANENT MAGNET GENERATOR
Currently, there are not many relevant studies in the literature for small steam turbines operating at low pressure, conditioned to the reality of the Amazon region. The main goal of this work is to develop an experimental study of a small steam turbine operating at low pressure, in order to apply it to small energy demand. It is used two bench setups. In the first one, a small steam turbine COPPUS, RLA Type is connected to a cyclonic combustor boiler with a permanent magnet electric generator of 1 kW. In this case, a load bank with equivalent resistance of 2.4 W is used to simulate the electrical load. In the second setup, the generator efficiency is investigated under pressures of 0.1, 0.2 and 0.3 MPa. The experimental bench for this setup is used to take measurements on the behavior of mechanical and electrical powers in relation to the shaft rotational speed of generator. We concluded that the preliminary experimental survey, made in this work, demonstrates a good mechanical behavior of the small turbine and could be an alternative for electricity generation system to supply small demands.
