If the rate of heat flow through a furnace wall is 0.94 kW/m². The wall consisting of 0.20 m thick inner layer of chrome brick, a center layer of kaolin brick of 10.0 cm and an outer layer of masonry brick 100 mm thick, having a thermal conductivity of 1.25 W/m°C, 0.74x10 kW/m°C and 0.555x103 kW/m°C respectively. The unit surface conductance at the inner surface is 74 W/m2 °C and the outer surface temperature is 70 °C . The temperature of the gases inside the furnace is 1670 °C , assume steady heat flow, Calculate the following: 1- The temperatures of the gases inside the furnace. 2- The interior surface temperature of the inner and outer layers.

Task 2 The transfer of heat from one fluid to another is an essential component of all chemical processes. Whether it is to cool down a chemical after it has been formed during an exothermic reaction, or to heat components before starting a reaction to make a final product, the thermal processing operation is core to the chemical process. It is essential that heat transfer systems for chemical processes are designed to maximize efficiency. Because the heat transfer step in many chemical processes is energy intensive, a failure to focus on efficiency can drive up costs unnecessarily. Task expected from student: a) Compare the basic design between the classifications of heat exchanger equipment's (Any three HE equipment's). b) Summarize the merits, demerits, limitations and applications of heat exchanger equipment's with neat sketch.
