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...

Pedal Operated Hacksaw

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 some weight to the upper saw frame in order to have some load on the hacksaw for a cut through movement system.
Components

Automated Portable Hammering Machine

Automated Portable Hammering Machine Hammering is the most widely used industrial as well as construction activity. Hammering or screws, metal sheets, parts etc requires a lot of time and effort. So here we propose an automated hammering system that allows for fully automatic hammering process. This allows for accurate, fast and automated hammering wherever and whenever needed using a 12V battery. The person just needs to insert workpeice and start the hammering machine. This machine can be used for automatic hammering work as and when needed. We here use a dc motor in order to move the hammer. The DC motor consists of a pulley attached to it which is connected to a larger pulley for efficient power transfer and to increase torque. This large pulley is connected to a shaft that has a connecting rod attached to it. This rod is used to achieve lateral motion from the spinning shaft. We now connect the other end of hammer to this connecting rod through a mid swinging arrangement in ...

Automatic Paper Cutting Machine Using Geneva Mechanism

Here we propose the design and fabrication of a fully automated paper cutter based on geneva mechanism. Our proposed system cuts paper pieces of equal lengths based on geneva mechanism. System uses a 12V motor in order to drive the entire system. We use a shaft which is directly connected to the motor. This shaft has a connecting rod which is connected to a scissor in order to drive the cutting mechanism for cutting paper. This motor shaft is connected to a sprocket which is in turn connected by a chain to another sprocket. This sprocket is now connected to a genava mechanism wheel. This wheel is used to drive paper feed into the cutter mechanism. Here we use geneva mechanism driven by another connecting z shape rod. This mechanism ensures paper feed of equal length inserted at proper time intervals. System uses a supporting frame that maintains proper coordination between feed and cutting mechanism.
