Thermal Conductivity

2. Objective
Furnaces or chemistry plants need insulation materials and heat protection equipment. To design equipment, heat loss needs to be calculated. Thermal conductivity is essential information for the calculations.

C. Discuss the situation when the experiment is performed at different temperatures 100℃, 200℃ and 300℃
(1) We performed the experiment near 200℃. (test piece A in 201℃ and 233℃ / test piece B in 200℃ and 230℃). If only the temperature changed to 300℃ and other conditions are same, the temperature difference between the ambient and the heat source will be greater than the experiment of 200℃. The greater temperature difference is associated with an increase in amount of heat lost. The increase in temperature difference will increase the amount of heat lost by heat flow about conduction, convection, and radiation although there is a hold protector that have a role of preventing heat loss.
