Fabrication Of Miniature (Mini) Boiler
SYNOPSIS
Mini boiler is convert water into steam energy. A mini boiler is consisting of a boiler, heater and gate valve. This pressurized steam is given to the 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.
INTRODUCTION
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, which 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. The industrial revolution, which began with the discovery of the steam engine (AD 1700), brought about great many changes. For the first time, man began to use a new source of energy, viz. coal, in large quantities.Check Out: Introduction to Boilers | Classification Of Boilers
WORKING PRINCIPLE
The block diagram of mini boiler is shown in figure, it consist of a tank, a.c heater and gate valve. The water is kept in the tank with the help of opening the tank. The water is heated with the help of A.C heater. In that time, the gate valve is closed. The steam is produced by heating the water above 100 degree C. The inside steam is pressurised steam.
This steam is used to rotate the turbine to produce electricity or other application.
The quantity of the steam is controlled by the gate valve.
ADVANTAGES
- Steam is produced by the simply the Heating the water
- This is a Non-conventional system
- High pressure steam produced
- Compact in size
DISADVANTAGES
- Initial cost of this arrangement is high.
- Input power supply needed
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 electricity also has been developed.
Electric Generation Applications:
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.
This unit can be integrated with existing hydro electrical networks and used in a “water-saver” mode of operation. When the water is blowing, electrical an amount equal to the being can reduce generation at the hydroelectric plants in the network produced by this unit. Thus, the water turbines supply part of the network load that is ordinarily produced by the hydroelectric generators. Under these conditions some of the water that would have been used by the hydroelectric plant to supply the load is saved in the reservoir and made available for later use when the water is not blowing.
