You are to design an electrically powered steam generator for use in a laboratory experiment. The boiler is to provide 1 g/s of dry saturated steam at 150 kPa. The primary design considerations are cost, ease of use, and safety. For simplicity, you may consider a pool boiler arrangement, with an electric-resistance heating element similar to that used in a tea kettle. Discuss how the electrical heating element would be sized and attached, placed in the pool, water quality issues, and how you would control the device to ensure that it could produce steam continuously.
