  3. James Watt : A Statue !!! • Mrs. Campbell, Watt's cousin and constant companion, recounts, in her memoranda, written in 1798: • Sitting one evening with his aunt, Mrs. Muirhead, at the teatable, she said: • "James Watt, I never saw such an idle boy; take a book or employ yourself usefully; • for the last hour you have not spoken one word, • but taken off the lid of that kettle and put it on again, • holding now a cup and now a silver spoon over the steam, watching how it rises from the spout, • and catching and connecting the drops of hot water it falls into. • Are you not ashamed of spending your time in this way? "

  4. A Message to 20th Century • The problem of which Watt solved a part is not the problem of inventing a machine, but the problem of using and storing the forces of nature which now go to waste. • James Watt’s law: "The cylinder is kept as hot as the steam that enters." • "How simple!" you exclaim. • “Is that all? How obviously this is the way to do it!" • Very true, surprised reader, but true, also, that no condenser and closed cylinder, no modern steam engine. • “How is it Better?’’ • A Kilogram of weight can be lifted through more distance using one kilogram of steam! • “How Big is this Engine?’’ • A small engine is equivalent to Few Horses : Horse Power! • How to harness this power and store it-that is the problem of the inventor and the engineer of the twentieth century, a problem which in good time sure to be solved.

  5. James Watt : Father of Performance of A Prime Mover • James Watt was born in Greenock in 1736, the son of a ship's chandler (trader in canvas, etc). • In his late teens he went to London to learn to be a "mathematical and philosophical instrument maker“. • He got a job making instruments with Glasgow University, who gave him accommodation and a workshop. • In 1763 John Anderson asked him to repair a New Comen steam engine he had acquired. • Two years later, while wandering aimlessly through Glasgow Green, Watt hit upon the idea of condensing the steam in a separate vessel. • In 1882, 63 years after Watt's death, the British Association gave his name to the unit of electrical power.

  6. The Concept • Performance: Production Capability & Efficiency of Power Plant & Equipment. • The performance of a power plant can be expressed through some common performance factors as • ·     Heat rate (energy efficiency) • ·     Thermal efficiency • ·     Capacity factor • ·     Load factor • ·     Economic efficiency • ·     Operational efficiency • Performance Analysis : Evaluation of performance factors using measured plant data. • Design Performance : Where You Should Be • Monitored Performance: Where You Are
