Steam power plants convert mechanical energy from steam into electrical energy. Steam is generated in a boiler and powers a turbine connected to an electrical generator. The generator produces DC electricity that is stored in a battery. An inverter converts the DC voltage from the battery to AC voltage that powers loads like lamps. Steam power plants have advantages of using renewable steam energy but also have high initial costs and require a fuel source to generate the steam.

1. STEAM POWER PLANT
ABSTRACT:
Steam Power Plant is convert Mechanical rotary energy into Electrical energy. A
mechanical interface, consisting of a boiler, heater and a suitable coupling transmits the
energy to an electrical generator. The output of this generator is connected to the Battery
or system grid. The battery is connected to the inverter. The inverter is used to convert DC
voltages to AC voltages. The load is drawn current from the inverter.
Generator
Mains shaft with Leafs
Amount of Steam (or) Pressure
The power ratings can be divided into three convenient grouping, small to 1kW, medium
to 50 kW and large 200 kW to megawatt frame size.

2. SCOPE OF THE PROJECT:
MAN AND ENERGY:
Man has needed and used energy at an increasing rate for its sustenance and well being ever since
he came on the earth a few million years ago. Primitive man required energy primarily in the
form of food. He derived this by eating plants or animals, whic h he hunted. Subsequently he
discovered fire and his energy needs increased as he started to make use of wood and other bio
mass to supply the energy needs for cooking as well as agriculture. He added a mew dimension
to the use of energy by domesticating and training animals to work for him.
With further demand for energy, man began to use the wind for sailing ships and for driving
windmills, and the force of failing water to turn water wheels. Till this time, it would not be
wrong to say that the sun was supplying all the energy needs of man either directly or indirectly
and that man was using only renewable sources of energy
WORKING PRINCIPLE
The block diagram of steam power plant is shown in figure, it consist of a boiler unit, 12 voltage
battery, an inverter and a florescent lamp. As we studied from the generator gives a D.C. output
of 12V this D.C. output is not always constant there is some variation in this D.C. output this
cannot be given to the battery storage it may weaken the life of the battery. So in order to get
constant D.C. output and also to avoid the reverse flow of current to the panel in the case of no
load a charge controller have been used this help us to allow only the constant voltage of 12V
D.C. to the battery and also it act as an blocking diode and protect the motor principle.
By this way the battery gets charged then this D.C. storage is given to an inverter this
inverter inverts 12V D.C. to input in to AC output, step upped in to 230V.The 230V AC supply is
given to the supply to the lamp. The lamp used for street lighting is 230V, 50 Hz, single-phase
supply.

4. APPLICATIONS
Direct heat applications
Mechanical motion derived from water power can be used to drive heat pumps or to
produce heat from the friction of solid materials, or by the churning of water or other fluids, or in
other cases, by the use of centrifugal or other types of pumps in combination with restrictive
orifices that produces heat from friction and turbulence when the working fluid flows through
them. This heat may then be stored in materials having a high heat capacity, such as water,
stones, eutectic salts, etc.,
A home heating system that uses a water powered pump and a restrictive orifice to derive
direct heat for a building, without first generating electricityalso has been developed.
Electric GenerationApplications:
Water power can be used in centralized utility applications to drive synchronous A.C.
electrical generators. In such applications the energy is fed directly into power networks through
voltage step-up transformers.
