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  gas emissions. In  this report,  we  gave  an  overview  of  the  currently  available information  on  the  different  process  ste...

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 local ma...

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 fundamentals of cryogenic engineering...

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 deve...

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...

WASTES AND SEWAGE AS A SOURCE OF ELECTRICITY GENERATION

ABSTRACT Waste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to energy (electricity) using different technologies including collecting and converting current landfill gases, wet or dry anaerobic ...

DESIGN AND FABRICATION OF MINI COPULA FURNACE AND AN ATOMIZER FOR THE PRODUCTION OF POWDERED METAL FROM WASTE ALUMINIUM CANS

ABSTRACT This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design drawings.Mild steel was used for the internal linings of the furnace casing while other materials were selected based on functionality, durability, cost ...
