  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

  • Mixers and Flowmakers: Mixers at BNR plant in Borås, Sweden

    Borås Treatment Plant, the Gässlösaverket, is situated at the river Viskan which is also the recipient. The plant is the largest single discharge to the Viskan, and since the water does not pass any lakes on its way to the sea, the reduction of nitrogen is small. Due to requirements with regard to the reduction of nitrogen discharge set out by the Swedish environmental authorities, the Borås ...
