Waste block turbine and generator in Iru Thermal Power Plant

Summary[edit]

Warning The original file is very high-resolution. It might not load properly or could cause your browser to freeze when opened at full size.
Description
English: This is the turbine hall of the Iru Thermal Power Plant in Estonia. The turbine and generator of the waste block are located in the older part of the power plant, in the same hall together with the turbines of gas boilers. The hot 400-degree steam from the waste incineration boiler is piped to this blue turbine. The steam travels under high pressure through the dense blades of the turbine and makes it rotate quickly. The generator is connected to the turbine by means of a shaft, and when the generator rotates, electricity is generated, which is conducted by means of cables at a voltage of 10.5 kV to the transformer behind the wall of the power plant. It raises the voltage to 110 kV, and via Elering's high-voltage power lines, the generated electricity is distributed all over Estonia. By means of a turbine and a generator, only up to 40% of the energy of the steam can be converted into electricity in a thermal power plant. More than 2/3 of the energy of the steam remains as heat, and because of this simple fact, cogeneration in both boiler and nuclear power plants is the most cost-effective and environmentally friendly way of producing electricity - to produce electricity and heat together.
