Question

This term project primarily aims to make the students think out of the box and try to solve a given problem using their existing knowledge/experience and by exploring the relevant information from books (e.g., use of library) and web search. The students will build confidence in solving unknown but relevant problems in the field. The students will improve their teamwork skills. Scope The scope of the project is slightly above the level of usual class-work such as homeworks, exercise and practice problems. Background As we know, pulp and paper manufacturing involves a great deal of humidity, which presents a preventive maintenance and corrosion challenge. A paper mill is a factory devoted to making paper from vegetable fibers such as wood pulp, old rags and other ingredients using a Fourdrinier machine or other type of paper machine. The modern paper mill uses large amounts of energy, water, and wood pulp in an efficient and complex series of processes, and control technology to produce a sheet of paper that can be used in diverse ways. Scenario I Suppose that you were hired by a paper mill as an engineer, which is planning to use some of its waste products as an energy source from excess process steam, it means that the management is looking for installing turbine generators to produce electricity. Assume that the company has the following choices: Three 10MW turbine generators, or One 20MW and one 10MW turbine generator, or A single 30MW turbine generator. As a company's engineer, you were asked to give your opinion/recommendation about the three given choices to build this new electric co-generation facility. Also, the company advised you to consider cost, reliability and efficiency as the most important factors while giving your recommendation. What will be your choice/recommendation? Justify your answer by explaining the advantages and disadvantages of each choice and support your claim.

Explanation / Answer

coming to the question it is nothing but optimising the given resources.

from case (1) :

if you want to supply a demand of 9 MW , as the three 10 MW generators are connected in parallel. only one can be in service to satisfy that demand . no energy wastage. if the demand increases the remaining generators can be connected in parallel with theexisting one.

highly reliable and low cost

from case(2)

if you want to supply a demand of 9 MW the only 10MW can be connected if the demand is 17 MW only 20 MW can be connected so there exists flexibility.

but the reliability is some what less compared to three 10MW in case 1

and the cost of single 20 MW generator is greater than cost of 2 10MW generators

from case (3) :

if you want to supply a demand of 9 MW then we have to connect one 30 MW generator and remaining 21 MW is of no use .. lot of energy wastage and realiabily is very less because if any fault occurs the generator is out of service.
