Abstract

Heat transfer is performed experimentally in the outer coil insulation and the 
externally finned coil. Experiments are performed with a total height of 50 cm and an 
inside diameter of 1.5 cm. A length of approx. 4 m and an inside diameter of 0.44 cm 
were used with with external small fins (approx. 266 fin)   During the experiments, three 
different hot water   flow rates and five different cold water  flow rates were tested with 
a constant temperature difference (∆T = 20 ℃). The temperature distribution along the 
heating equipment and the heating rate were determined and discussed. The results 
showed that the temperature of the projectile increased with altitude, which was 
positively affected by the flow of the projectile mass. The accepted value of the lateral 
rotational speed of the front was determined in accordance with the current operating 
conditions. Finally, the heat transfer rate was significantly affected by the mass rate of 
coil side.
