Example of Rankine Cycle - Problem with Solution. Let assume the Rankine cycle, which is the one of most common thermodynamic cycles in thermal power plants. In this case assume a simple cycle without reheat and without with condensing steam turbine running on saturated steam (dry steam). In this case the turbine operates at steady state with inlet conditions of 6 MPa, t = 275.6°C, x = 1
Question: Boiler pressure In tanker vessels we use boilers for cargo heating. Lets say that steam pressure to deck line adjusted to 5 bar. What will be most economical? Boiler pressure adjusted to 7 bar or to 16 bar ? Answer: The higher pressure would be advantageous if the boiler is oil-fired, but the difference is hardly measurable.
Answer: Soot on the heating surfaces. Even a thin layer of soot will reduce the boiler efficiency. Not the right fuel for the burner. For instance, diesel oil to a rotary cup burner wouldn't do. Too low feed water temperature. Boiler Questions and Answers

Answer: The water enters the boiler from the cascade tank will evaporate .Produced steam is very fine and will contain so chloride as it is heavier .So the chloride will remain in the water drum. As more feed water will enter the boiler the chlorides will be added .This process is continuous and if the chlorine id not blown down regularly it
Ans: Water tube boilers raise steam fast because of large heat transfer area and positive water circulation. Thus they respond faster to fluctuations in demand. Further single tube failure does not lead to catastrophe. 24. What type of boiler does not need a steam drum? Ans: Super-critical pressure boiler. 25.
