Energy Technologies & Resource Saving| Summary: | Electrization of working fluid in the wet steam turbine results in occurrence of electromagnetic radiation in the exhaust part of the turbine. The purpose of the investigation is experimental study of parameters electromagnetic radiation and discuss its influence on the efficiency and reliability of turbine. Electromagnetic radiation received by string antennas in the turbine exhaust part. Measurement of electromagnetic radiation parameters was carried out by using a spectrum analyzers. It has been found electromagnetic radiation in the form of noise from kilohertz to tens of megahertz. It was also found high frequency component near 2 GHz. Total power of the electromagnetic radiation of ionized wet steam flow in exhaust part turbine can reach several kilowatts. Proof of this can be found in the experiment damage of cables insulation laid in the turbine condenser. Another manifestation electromagnetic radiation are high frequency current induced in the electric circuit of the probe installed in the exhaust of the turbine. Results presented in the paper show that the electromagnetic radiation can affect on performance and reliability of the wet steam turbine |
