Abstract
Ever since the dawn of civilization, man has always been using mechanism and machines, which will support and help him to realize his dreams and desires, Energy convertors are one of its kind and have been man’s best friend to make his life better and easier. With the development of science and technology, new mechanism and devices were available to man to aid him in this task. Invention of turbines enabled him to develop a lot, which were later mechanized, and today we have a variety in it. With the development of turbines, man human kind was able to push to the limits of inventions and innovations. This project summarizes the utilization of a kinetic energy going waste in our daily life which can be used to light up the darkness in many ways, new innovations being developed, and breaking the barriers to further development. In this light on a very simple kind of a traditional turbine i.e., a Pelton Wheel Turbine and how we make use of it to harness the energy running in the water pipes of our houses and convert it to usable form of electricity to use for lighting the house at night and load shedding. Thus making the environment greener by saving on Government supplied electricity. Key Words: Kinetic Energy, Turbine, Electricity, Load Shedding, Greener.
1.1 OBJECTIVE OF THE WORK There are 3 main works that we have set for this project and are as follows. 1.
Turbine and generator must adequately charge the battery whenever they run.
2.
To check that turbine works at maximum efficiency always inside the enclosed chamber.
3.
Handling and maintenance of the device should be very easy, handy & cheap.
1.2 TARGET SPECIFICATIONS
As we observe that the energy generated from this setup is sufficient enough to light a room for about 6 to 7 hours which is great importance during power cut offs, this will serve the purpose of human comfort to some extent. This will help to save energy and the saved energy can be utilized by the people of rural areas for agricultural purpose and development of nation is possible.
1.3 LITERATURE SURVEY
We have studied in fluid mechanics that if at the inlet of the turbine, the energy available is only kinetic energy, the turbine is known as impulse turbine. As the water flows over the vanes, the pressure is atmospheric from inlet to outlet of the turbine. The construction and installation of this turbine is much simpler and economic process and it also provides maximum power at the output and hence this setup includes a pelton wheel blades or turbine. The pelton wheel is a tangential flow impulse turbine. The water strikes the bucket along the tangent of the runner. The energy available at the inlet of the turbine is used for high heads and is named after L.A.Pelton, an American Engineer.
1. INTRODUCTION There are two types of turbines, reaction & impulse, the difference being the manner of head conversion. In reaction turbines the fluid fills the blade passages, and the head change or pressure drop occurs within the runner. An impulse turbine first converts the water head through a nozzle into a high-velocity jet, which then strikes the buckets at one position as they pass by. The runner passages are not fully filled, and the jet flow past the buckets is essentially at constant pressure. The Pelton turbine used in this project is an impulse turbine. The Pelton turbine consists of three basic components as shown in Figure. A stationary inlet nozzle, a runner and a casing. The runner consists of multiple buckets mounted on a rotating wheel. The jet strikes the buckets and imparts momentum.
1.4 BRIEF BACKGROUND THEORY As it can be seen from the picture above that is the rain water is collected and forced onto a pelton wheel and the power is extracted. This generated power is saved in a battery of desired capacity and used whenever needed. This basic knowledge is used for our project and limitations of being used only during rainy seasons are eliminated and can be used for whole year without being dependent on natural resources such as rain.
1.5 PRESENT STATE / RECENT DEVELOPMENTS IN THE WORK AREA As seen from the previous invention of portable green unit how the rain water is made use for the generation of power and extracting the benefits from it, there the roof water was
