  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Regenerative Turbine Aeration Technology

    In order to acquire precise control of input and output fluid/gas parameters, wastewater managers and technicians can utilize a regenerative turbine pump, which fully optimizes the gas dissolution process that properly treats wastewater, time after time. Once such parameters have been completely controlled, a well-designed wastewater treatment system should be able to initiate all necessary ...

  • Are wind turbines economically viable in Britain?

    If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...

  • DAF Regnerative Turbine Aeration Technology

    Gas is dissolved into a fluid through pressure in any DAF application.  The regenerative turbine pump applies pressure through a triple action force (centrifugal, axial and friction) to the gas and fluid during a single pass through the pump head.  Whether disolving compressed or atmospheric air, nitrogen or other gases to the fluid, the regenerative turbine pump achieves the highest ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • Pumps as turbines (PATs) in water distribution networks affected by intermittent service

    A hydraulic model was developed in order to evaluate the potential energy recovery from the use of centrifugal pumps as turbines (PATs) in a water distribution network characterized by the presence of private tanks. The model integrates the Global Gradient Algorithm (GGA), with a pressure-driven model that permits a more realistic representation of the influence on the network behaviour of the ...

  • The Real Cost Associated With Neodymium Wind Turbines

    According to a research organized by a group of UK scientists, it is predicated that 15% of the country’s energy requirements in the year 2020 are expected to come from renewable energy sources. They have also considered about the wind farms that are popping in every corner of the country to come into this conclusion. These reports have created several contradictions among people as well. ...

  • Pump as turbine implementation in a dynamic numerical model: cost analysis for energy recovery in water distribution network

    In complex systems characterized by the presence of private tanks and water scarcity conditions, water managers usually apply intermittent distribution, trying to reduce the water volumes supplied to the users and pipe leakages, or use pressure reduction valves for controlling pressure in the network. The application of pumps as turbines (PATs) appears as an alternative and sustainable solution ...

  • A new design of a highly efficient hydraulic turbine on the basis of the specific hydrodynamic effect

    Traditional free flow turbines slow down water stream using its kinetic energy. This article describes a method for deriving energy from a free water stream using a unique hydraulic turbine which unlike traditional hydraulic turbines speeds up the water stream using potential energy thanks to a specific hydraulic effect. The article also describes a method of mathematic calculations of output ...

  • Energy Efficient Vertical Turbine Pumps Promote Sustainable Mining Efforts

    The computational fluid dynamics process advances highly efficient pump designs for difficult applications. Energy is a strategic input for the mining industry in Latin America and worldwide. Mining requires large amounts of energy, which drives up total operational costs. In Chile, mining companies consume 34 percent of the total energy produced in the country and spend approximately ...

  • Exergy analysis of gas-turbine systems with high fogging compression

    Gas-turbine cycles with high fogging compression could offer enhanced efficiency and low complexity. Whereas compression power and heat rates decrease when small amounts of water (up to 2% of air flow by mass) are injected at the machine inlet, increased injection amounts could allow implementation of regeneration, further decreasing the heat rate. In this study, an exergy analysis is carried out ...

  • Cogeneration steam power desalting plants using steam turbines

    This paper presents the reasons and merits of using cogeneration generation power desalting plants (CPDP), the different methods used to rate their performance, and their drawbacks. The ratings of the CPDP are crucial, because the fuel cost allocation between the water and power depends on the rating method used. The ratings are usually based on the first and the second laws of thermodynamics. A ...
