  • 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 ...

  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • Performances of photovoltaic water pumping systems: a case study

    This paper presents a mathematical motor-pump model for photovoltaic (PV) applications which allow us to contribute in the studies of PV pumping sizing. The modelled motor-pump characteristic is flow rate-power (Q, P). The model is established for centrifugal pump (CP) coupled to DC motor. The non-linear relation between flow rate and solar power has been obtained experimentally in a first step ...

  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • Introduction to the BioCar Nature Based Transportation Systems

    The people of the world are rapidly growing aware of the full impact of current transport systems upon their safety, economy, health and environment. This has not been lost on the major auto companies who have spent millions of man-hours and billions of dollars over the last decade in pursuit of the Next Generation Vehicle. But they have little to show for their efforts having been increasingly ...


  • Mercury and other trace elements in Ohio River fish collected near coal‐fired power plants: Interspecific patterns and consideration of consumption risks

    Many coal‐fired electric generating facilities in the US are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food webs. We evaluated the concentrations of As, THg, ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...
