Automatic Temperature Control In Vacuum Brazing Furnace Using P.L.C

ABSTRACTBrazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel as based filter material in air or atmosphere the braze joint will porous and braze strength is not achievable. To avoid the presence of oxygen while brazing, either inert gas furnace or vacuum furnace can be used. Vacuum furnace is superior to inert gas controlled by furnace ...

Production Of Biodiesel From Jatropha Crop

ABSTRACT:    The interest in using Jatropha  curcas  L.  (JCL)  as a feedstock for  the  production  of  bio-diesel  is  rapidly  growing.   The  properties  of  the  crop  and  its  oil  have  persuaded  investors and policy  makers to consider  JCL  as  a  substitute  for  fossil  fuels  to reduce  greenhouse&nbsp...

Biostimulation Of Crude Oil Contaminated Soil Using Local And Foreign Stimulants

ABSTRACT Bioremediation is an important technology for the restoration of oil polluted environments by indigenous or selected microorganisms. In general, the rate of biodegradation depends on the number and types of micro-organism, the nature and chemical structure of pollutants to be degraded and the environmental conditions. In this study, the efficacy of the biodegradation potentials of foreign (  PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339 ) and loca...

Cryogenic Science And Engineering

   ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics     Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundament...

Design of a Hudraulic Escalator

ABSTRACTAn escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage are; shopping malls, airports, transit systems, convention centers, hotels, and public buil...

Thermodynamic Principle Of Energy Conversion

ABSTRACTEnergy conversion engineering (or heat-power engineering, as it was called prior to the Second World War), has been one of the central themes in the development of the engineering profession. It is concerned with the transformation of energy from sources such as fossil and nuclear fuels and the sun into conveniently used forms such as electrical energy, rotational and propulsive energy, and heating and cooling. A multitude of choices and challenges face the modern energy conversioneng...

DESIGN OF MANUAL CHIP PACKAGING MACHINE

ABSTRACTPackaging of food which is viable means of  business opportunity has been exploited by individuals and corporate bodies for a very long time because the importance of packaging food products are very enormous ranging from protection of the product to preventing the food from spoiling. There is no way one can successfully go into business of chips production without exploiting a proper means of packaging the product. Over the years, different types of packaging machines have been ...

GENERAL OVERVIEW OF RENEWABLE ENERGY

ABSTRACTThe rapid increase in energy consumption particularly in the past several decades has raised fears of exhausting the globe’s reserves of petroleum and other resources in the near future. The huge consumption of fossil fuels has caused visible damage to the environment in various forms. Approximately 90% of our energy consumption comes from fossil fuels. Due to industrializations and population growth our economy and technologies today largely depend upon natural resources, which are...

An Overview Of Remediation Techniques Of The Environment

ABSTRACTOil spillage which can simply be referred to as the release of oil into the environment (land or water) either through a deliberate act, accident or as a result of equipment failure indeed has an alarming effect on the affected communities due to the fact that it either renders the environmentuseless or sometimes take a longer time for the affected area to have a natural process of attenuation.In addition, having given the necessary compensation to the affected communities in line wit...

REPAIR AND REHABILITATION OF A FAULTY AIR- CONDITIONER IN ENGR. AYOGU AND OKPE’S OFFICE AT INSTITUTE OF MANAGEMENT AND TECHNOLOGY (IMT) ENUGU

ABSTRACT In all types of air –conditioning work a through knowledge of basic principal is varying important. The report of the project “re pair and rehabilitation of a faulty Air–conditioner” serves as guide to project implementation. It explains and illustrates the import principle of operation and various maintenance procedures in an understanding manner.The report is divided into four chapters, which covers the practical application of air-conditioner in the field of domestic, bu...

A PROJECT REPORT ON THE REFURISHMENT OF FLUID FLOW DEMONSTRATION UNIT

ABSTRACTThe refurbishment of the fluid flow demonstration unit was carried out in the Chemical Engineering pilot plant laboratory of the Institute of Management and Technology Enugu.The refurbishment process was carried out to ensure adequate functioning of the unit, to allow the continuous use of equipment in the pilot plant, so that student would use it in understanding the nature of the flow of fluid through pipe lines, these process was also for the development of the knowledge of every o...

DESIGN AND FABRICATION OF AN ELECTRIC STOVE / OVEN

ABSTRACT In this project (3) alternative design solutions were considered for the locally made electric run. The authors utilize the available local raw demerits of each alternative with respect to the considered group were discussed and the solutions of the alternative that best satisfied the limitations was selected for production. Material selection, design and cost of analysis, production processes and operation maintenance and problems encountered during the design were also included.&n...

DESIGN AND OPERATION OFA SHELL AND TUBE HEAT EXCHANGER

INTRODUCTIONThe most common type of heat exchanger used in industry contains a number of parallel tubes enclosed in a shell and is thus called a shell and tube heat exchanger.  These heat exchangers are employed when a process required large quantities of fluid to be heated or cooled.  Due to their compact design, these heat exchangers contain a large amount of heat transfer area and also provide a high degree of heat transfer efficiency.Over the years, many different types of shell...
