Power Engineering 2

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Requires annual review of SOPs






2. Primary fuel produces high thermal energy for processes - the waste heat is used to produce electrical energy

3. Counter act force and load on thrust bearings






4. 1. prevent wear 2. reduce friction 3. remove heat 4. reduce corrosion 5. provide sealing






5. 1. CCME 2. CEQG 3. CWQG 4. US EPA






6. Air drawn from atmosphere - working fluid






7. 1. compressor discharge 2. condenser 3. liquid receiver






8. The condenser






9. Cooling of air between stages - condense below atmospheric temperature removing moisture - not primary function






10. 'booster' compressor






11. 1. spray 2. fog 3. special evaporator pads






12. At high temperatures a material stretches






13. Main purpose to protect the evnironment (air - water and soil) and create public awareness - involves training - monitoring and reporting






14. Controlled pressure from intermediate stages of turbine






15. Dry surface coolers - no contact convection hx - aka finned tube exchangers






16. Removal of exhaust gases by blow air through






17. Refers to the production of electricity form two sources utilizing one fuel source






18. An 'overrunning' clutch






19. 1. intake 2. compression 3. power 4. exhaust






20. 1. inlet to the convection section 2. betwen convection and radiant section 3. at radiant section outlet






21. As prime movers in pulp and paper industry






22. 1. compression ration across compressor 2. turbine inlet temperature






23. Use antifriction bearings






24. Atmospheric or hyperbolic






25. Straight condensing






26. Cause high discharge pressures - more power requirements - reduces capacity






27. The utilization of one form of input energy to generate two or more forms of output energy






28. The crankshaft and valve train






29. Fuel supplied firstg produces electrcial power with thermal energy as a by- product

30. 1. electricial purity 2. silver nitrate - milky white






31. Large turbines with a generator on each shaft






32. 1. Difference in pressure across moving blades 2. steam leaks around edges 3. minimal blade clearances 4. unbalanced thrust






33. Calcium chloride and water - -51






34. Increased efficiency due to decreased frictional losses






35. 1. verticle cyclinder 2. cabin heater 3. central tube wall






36. Ground water monitoring device






37. Reduces steam pressure and velocity in two or more steps






38. Help maintain definite thrust toward exhaust






39. Made of polyethylene - skimming from the surface






40. Means to come together and form one mass - removes oil and water from air






41. Results in a gain in velocity - the moving blades change direction producing force






42. 1. Responsive to speed changes 2. responsive to pressurre changes






43. 1. plate 2. channel






44. 1. lowers power consumption 2. load changes frequently 3. pilot valve controls loading - adjustable






45. Fall under provincal boiler pressure regualtions - wcb and local fire marshall regulation and insurance company - need log book - safety device testing records






46. Throttle body






47. Increase pressure affecting performance of condenser but do not incresase temperature






48. Direct prosses applications - absorption refrigeration - heat recovery boiler






49. 1. convergent 2. convergent- divergent






50. 1. lubricate sliding surfaces 2. cool bearings
