A SUCCESSFUL INDUSTRY BASED AND ENERGY CONSERVATION RELATED SENIOR PROJECT

ABSTRACT One such student and his manager proposed The Mechanical Engineering program at Union analyzing a cascade of industrial compressors that now College which is on a trimester system requires a two consumes electric power at the rate of more than $ term Engineering Senior Project with the option of 1,000,000 per year to better understand the system and extending to three terms. The normal procedure is to identify changes in design or operating procedures during the junior year each faculty member provides the that could reduce this electric power bill. students with a list of their interests and then the The system was modeled, property tables students can interview each faculty member that has a developed and analysis performed based upon the 1st project of potential interest before making the final and 2nd law of thermodynamics. This resulted in decision. The alternative procedure is for the student to identifying a change of operating procedures that define a project and then find a faculty member to work reduced power requirements by 15 % and additional with. recommendations for equipment modifications and Most of the students are full time day students, but upgrades. This paper will describe this project. there are significant numbers of students who are employed by local industries and attend part time, and 1. Introduction these students often propose work related projects to Laboratory based research development and various faculty members. Such projects have included testing of gas turbine and aircraft engine combustion methods for deicing airplane on ground and in flight, processes requires a supply of compressed air at design and installation of an autopilot system for an pressures, temperatures and flow rates comparable to airplane, analysis of air infiltration to and from hospital the operating conditions from the compressors of the clean rooms and performance of tests and analysis actual engine in which the compressor is powered by the directed toward increasing the efficiency of a cascade of turbine. However, in the laboratory the compressed air power intensive industrial compressors. is typically provided by a cascade of compressors with This paper will describe each of these four projects some intercooling and driven by large nominally fixed and then provide a detailed description of then a more speed three phase induction motors. The control of the complete presentation of the tests, analysis, output pressure and flow has been performed with a recommendations and results of the industrial combination of throttle and dump valves in the cascade compressor senior engineering project that is now while final temperature is attained by natural gas fueled saving the industry about $100,000 per year in electric heaters. An existing system has had an energy cost in power costs by changing the operating configuration excess of $2,000 per hour.
