Chemistry

A manufacturing facility requires saturated steam at 120°C at arate of 1.2 kg/min. Design an electric steam boiler for thispurpose under these constraints: • The boiler will be incylindrical shape with a height-to diameter ratio of 1.5. Theboiler can be horizontal or vertical. • A commercially availableplug-in type electrical heating element made of mechanicallypolished stainless steel will be used. The diameter of the heatercan be between 0.5 cm and 3 cm. Also, the heat flux at the surfaceof the heater cannot exceed 150 kW/m2. • Half of thevolume of the boiler should be occupied by steam, and the boilershould be large enough to hold enough water for a 2-h supply ofsteam. Also, the boiler will be well-insulated. You are to specifythese: (1) The height and inner diameter of the tank; (2) thelength, diameter, power rating, and surface temperature of theelectric heating element; and (3) the maximum rate of steamproduction during short periods (less than 30 min) of overloadconditions, and how it can be accomplished
