In a thermal power plant, stainless steel (SS) pipe is used to carry the steam generated from the boiler section to the turbine section. The condition of the generated steam is super-heated at 600°C. The inner and outer diameters of the SS pipe are 300 mm and 320 mm respectively. To minimize the heat loss from the steam during transportation, it is suggested to add a layer of calcium silicate insulation of thickness 50 mm over the SS tube. Consider the thermal conductivity of SS and calcium silicate as 45 W/m- K and 0.15 W/m-K respectively. Assuming the inner wall temperature of the SS tube equal to the temperature of super-heated steam and the bulk temperature of the surrounding fluid medium as 27 °C with convective heat transfer coefficient as 6 W/m²-K, a. Draw the electrical network with appropriate symbols if thermal resistance due to imperfect contact between the pipe and insulation layer is Rc b. Determine the heat loss per unit length of the pipe if Rc= 1x 10-³ m²-K/W Find the inner and outer temperature of the insulation layer and also sketch the temperature profile in the pipe and insulation layer.
