Internship is an great opportunity for us to have an hands on practical experience of the things which we learn theoretically in class rooms. As engineers, it is of great importance for us to have the knowledge of how things actually work on site to have a clear picture of the subjects. Keeping this in mind, I would like to thank ‘Aditya Birla Group Carbon Black, Gummidipoondi Plant’ for giving me this platform to work on.
I would like to thank Mr. P.L. Das, H.O.D (HR Department), also Mr. R. Kumar & Mr. Vijay Karthik Reddy of thr HR Department, who have played an important role in giving me this opportunity and also carry it smoothly during the entire period of the intern. I would also like to thank Mr. Rajesh Kumar Mishra, H.O.D (Mechanical Department) who’s been kind enough to accept my proposal to carry out this internship program. Also, I am grateful to Mr. Mahidhar Varma & Mr. Vamsi Krishna Reddy who are part of the engineering team of the Mechanical Department. These people have played a crucial role in guiding me and making me understand the process and duties of the plant as an engineer. The knowledge inculcated by these people is really appreciable.
I am also grateful to Mr. E. Prakasam, Manager (Utility Department) without whom this project would have been impossible. He’s been really helpful in contributing his time and knowledge and complete this project successfully.
This chapter is all about discussing the theory and concept from the past projects. The objective is to explain the perspective and method which has been used in the past projects and to observe how this project can be related with existing research and theory. This shows how the theory and concept have been implemented in order to solve project problem. The theory understanding is crucial as a guidance to start any project. The result of a project cannot be assessed if it's not compared to the theory.
1. Introducing an additional combustion chamber to inject the additional suitable fuel and then allow it to expand which forms the part of turbo charger unit. And this additional fuel is burnt through the waste heat from the exhaust. Waste heat can be used to produce the electrical energy by using a thermoelectric generator.
2. In the third methodology energy recovery can be done by coupling a compressor and an alternator to the turbine
3. shaft for the production of electrical energy and air is compressed which can be used for running any auto auxiliaries.
Cogeneration is the method of simultaneous production of heat and other form of energy in a process. Many cogeneration techniques have been employed in IC engines to recover the waste heat. Turbo charging is also a kind of waste heat recovery technique in which the exhaust gases leaving the engine are utilized to run a turbine to produce power.
An exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes.
Depending on the overall system design, the exhaust gas may flow through one or more of:
a. Cylinder head and exhaust manifold
b. A turbocharger to increase engine power.
c. A catalytic converter to reduce air pollution.
d. A muffler / silencer , to reduce noise.
The chosen architecture for the electric motor is the Surface Permanent Magnet Synchronous Motor, which can assure a high torque density with reduced weight and space required. The electrical machine has its rotor keyed to the drive shaft of the internal combustion engine, and is capable to supply torque.
The battery pack has been designed considering Lithium-Polymer cells, which have the advantages of not being ammable and to have axeible structure that can assure a smarter usage of the available space.
There are two main types of generators.
1. Direct-current (DC) generators produce electric current that always flows in the same direction.
2. Alternating-current (AC) generators, or alternators, produce electric current that reverses direction many
Times every second. Both kinds of generators work on the same scientific principles. But they differ in the ways they are built and used. Basic Principles. A generator does not create energy. It changes mechanical energy into electrical energy. Every generator must be driven by a turbine, a diesel engine, or some other machine that produces mechanical energy. For example, the generator in an automobile is driven by the same engine that runs the car.
