  1. MEL 725: Power Plant Steam Generators P M V Subbarao Professor Mechanical Engineering Department A First Stage Technology for the Development of Civilization!!

  2. P M V Subbarao Mechanical Engineering, IIT Delhi Steam, The origin of Scientific & Industrial Civilization. • Trace the origin of steam. • Think about the impact of Steam on Science. • Enumerate the impact of steam on Technology. • Appreciate the role of steam in industrial world.

  3. The Philosophy of Steam -- Mill • There are many features which characterize this progressive economical movement of civilized nations. • The best of the best feature which excites attention – What is it? • This is the feature which intimately connected with the phenomena of production • This is the perpetual. • The unlimited growth of man's power over Nature so far as human foresight can extend.

  4. P M V Subbarao Mechanical Engineering, IIT Delhi Science of Cooking Methods Gas Stove Wood Stove Micro Wave Camp fire

  5. Science of Lighting Electric Lamp Gas Lamp Wick lamp

  6. P M V Subbarao Mechanical Engineering, IIT Delhi Science of Motive Power : Land Car Steam Wagon Horse Cart

  7. Science of Motive Power : Sea Steamer Steam Engine Ship Man power Ship

  8. P M V Subbarao Mechanical Engineering, IIT Delhi Science of Motive Power : Air Supersonic aircraft Turbojet Aircraft Propeller aircraft

  9. How Come?

  10. P M V Subbarao Mechanical Engineering, IIT Delhi Human being is a WEAK Animal Yet dominates the GLOBE !?!?!?! Human being has ability to provide power, set LIMITS to the rate of growth of Civilization.

  11. The Philosophy of Steam -- Mill • Our knowledge of the properties and laws of physical objects shows no sign of approaching its ultimate boundaries!!!!! • It is advancing more rapidly, and in a greater number of directions at once, than in any previous age or generation. • Affording such frequent glimpses of unexplored fields beyond as to justify the belief that our acquaintance with Nature is still almost in its infancy.

  12. P M V Subbarao Mechanical Engineering, IIT Delhi Origin of Steam : Basis of Scientific & Technological Research • Denis Papin, while working at Huygens and of Boyle, started to be interested in the vapor. • Several geniuses of science tried before him to try out an unspecified machine which would run on the vapor, but their efforts were useless. • It is into 1707 that Denis Papin made his first great realization: the boat with vapor. • This superb invention brought much controversy near the boatmen, who destroyed the ship.

  13. The Boiler ……… • Boilers are accepted equipment of everyday life. • A prime device which connects natural resources and human-made facilities. • A fire… • A furnace…. • A boiler ….. • A Steam generator.

  14. P M V Subbarao Mechanical Engineering, IIT Delhi The Steam Machines were in industrial use since 1712. Establishment of the first and second laws of thermodynamics by Clausius, Kelvin et al., occurred in 1855!!!

  15. This Led to Formulation of Greatest Science …. Thermodynamics

  16. P M V Subbarao Mechanical Engineering, IIT Delhi Thermodynamics A Science of Human Development through Energy Utilities.

  17. Depth of Knowledge of Thermal Sciences isA Measure of Growth of Technology & Civilization……
