Thermal Power Plant : Principle, Parts, Working, Advantages and Disadvantages

Basic Introduction or Principle: We all are aware with the term "Generator". A device which converts mechanical energy into electrical energy is known as generator. This generator makes rotate with the help of some kind of external energy. When this energy extract from the energy of steam, the plant is known as steam power plant.  A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a  boiler   which converts it into high pressurized super heated steam. This high energized steam passes through steam  turbine  (a mechanical device which converts flow energy of fluid into mechanical energy) and rotate it. Owing to extract full energy of steam, three stage turbines is used which is known as LPT (Low pressure turbine), IPT (intermediate pressure turbine) and HPT (High pressure turbine). The turbine shaft is connected to the generator rot

Differential Gear Working

Differential is the main component of the power train. It is bolted on the rear axle and connects the propeller shaft to the rear wheels. While a vehicle taking a turn, its outer wheel run faster than the inner wheel. If we connects the propeller shaft by rear axle without using of differential gear, than the torque transmitted both the rear wheels is equal in any condition. So the both rear wheels will run at same speed while taking a turn which occur a problem in driving a vehicle. To eliminate this problem a device is used which is known as differential gear.

Differential is the mechanism of gears by means of which outer wheel runs faster than the inner wheel while taking a turn or moving over upheaval road. It is a part of the driving axle housing assembly, which includes the differential, rear axles, wheels and bearings. It consists of a system of gear arranged in such a way that connects the propeller shaft with the rear axle and transmit the different torque to rear wheels if necessary. 


Differential Gear:

Construction of differential gear:


Differential is an arrangement of gears which work together and allow the vehicle to take a turn smoothly. In the differential, bevel pinion gear is fixed to the propeller shaft which rotates the crown wheel. The crown wheel has another unit called the differential unit. It consists of two bevel gears (sun gear) and two bevel gears (planet gear). The bevel gears are in contact with the half shaft of the rear axle. When the crown wheel is rotating, it rotates the differential unit. The bevel (sun) gears of the differential rotate the two shafts.

What is Differential Gear Used in Automobile?

Working of differential gear:

When the car is on a straight road, the ring gear, differential case, differential pinion gears, and two differential side gears all turn as a unit. The two differential pinion gears do not rotate on the pinion shaft. This is because they exert equal force on the two differential side gears. As a result the side gears turn at the same speed as the ring gear, which causes both drive wheels to turn at the same speed also. However, when the car begins to round a curve, the differential pinion gears rotate on the pinion shaft. This permits the outer wheel to turn faster than the inner wheel.

Its Working can be easily understandable by following video.

New imaging technique could detect acoustically 'invisible' cracks

The next generation of aircraft could be thinner and lighter thanks to the development of a new imaging technique that could detect damage previously invisible to acoustic imaging systems. The nonlinear acoustic technique developed by researchers from the University of Bristol's Ultrasonics and Non-destructive Testing (NDT) research group is published in the current issue of  Physical Review Letters  together with an accompanying article in  Physics . It has long been understood that acoustic nonlinearity is sensitive to many physical properties including material microstructure and mechanical damage. The lack of effective imaging has, however, held back the use of this important method. Currently engineers are able to produce images of the interior of components using ultrasound, but can only detect large problems such as cracks. This is like detecting only broken bones in a medical environment. Imaging of acoustic nonlinearity is achieved by exploiting differences in

Main Parts of an Internal Combustion Engine

Today we will learn about main parts of an engine. An internal combustion engine is the engine in which combustion (burning of fuel) takes place inside the cylinder of engine. By burning of the fuel high temperature and pressure force generates. This pressure force use to move the vehicle or rotate wheels by use of some mechanism. In an engine many parts work together and achieve the goal of converting chemical energy of fuel into mechanical energy. These parts are bolted together and the combination of all these parts is known as engine. Today I am going to tell you about these parts and how they work so you can know the basic of automobile engine. Main Parts of an Internal Combustion Engine: 1. Cylinder block Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston. It is in direct contact with the products of combustion so it must b

Pedal Operated Hacksaw

Pedal Operated Hacksaw Operating a hacksaw manually is a very tiring and time consuming task. It requires a lot of manual effort and delivers uneven cutting. Operating a electrical hacksaw does deliver good results but consumes a lot of energy. So here we propose a semi automated hacksaw using pedal power. Here we design and fabricate a hacksaw that is run by pedal power and achieves even cutting with very less efforts. Here we use a chain sprocket arrangement to transfer power from pedals to hacksaw. A strong and firm base frame allows for efficient power transfer between the system. We use bearings and mounts to mount and setup the entire system and ensure a smooth circular motion of pedals. Now we attach a hub to the other sprocket. This hub is connected with a connecting rod which moves with the hub in order to produce a lateral motion. We now develop a supporting frame and connect a saw to the other end in order to achieve desired cutting movement of saw. We also attach
