Application of Microcomputers in Thermal Insulation Design and Analysis
Thermal insulation for hot surfaces of industrial installations such as storage tanks, steam and hot water pipes and other thermal process equipment is essential for their safe and economical operation. With the present high cost of fuel, inadequate insulation leads to excessive heat losses and higher operating cost. On the other hand, the effectiveness of the additional insulation diminishes as thickness increases. The concept of determining an optimum insulation has long been appreciated. However, the lengthy and laborious calculations required to establish heat losses through varying insulation thickness with a wide range of temperatures always discourage such optimisation exercise. Many resort to estimation based on previous experiences or guessed work. These will inevitably lead to under estimation as the increase of fuel price is not well incorporated.
