Comparison of cost price for kWh in 1-year and 10-year operation of the equipment.
Prospects for Utilisation
Industrial installations – water treatment plants, cooling and supply water circuits in industrial factories, water supply treatment plant, pumping and cleaning water from mines.
Fishery – fish hatcheries (where producing energy joins water aeration), inflow and outflow from lakes and other artificial tanks. The PROTUR turbines is possible to install to cascades.
Agriculture – Irrigation canals
Forestry – basic energy production in remote places where is not possible to deliver energy from grid (for ex. Protected Landscape Areas). For storing the energy can be used an independent island storage.
All streams, rivers, dams, weirs, canals and other sources of running water with a sufficient gradient and water flow are suitable for the installation of the PROTUR system.
The main advantage of the PROTUR system is the ability to work effectively with small water flow rates and low gradients. For example with a rotor diameter of 0.6 m, gradient 1 m and water flow rate of 100 l/s, the turbine has an output of 0.5 kW. The daily production is 12 kWh of electricity.
If four PROTUR I machines with total production of 10 kWh per day are connected to one system, on gradient 0.8 m, they will produce up to 3.7 MWh of electricity per year. A little bit more than one household consume annually.
Four of such turbines are installed at the Ledvice Power Plant on gradient 0.85 m and water flow 40 l/s per turbine. They also include a battery storage with a capacity of 12 kWh. In the search for the optimal application of connection of the rolling turbines was chosen the location at the outlet of the safety tanks of the wastewater disposal technology so that the residual energy potential of the treated wastewater leaving the power plant is used.
