The document provides data from a test on a flat-walled furnace with inner and outer brick walls of unknown conductivity. It gives the temperatures measured at various points within the furnace walls. It then calculates the percentage of heat loss that would be saved by adding 5cm of magnesia insulation to the furnace outer wall. Without the insulation, the heat loss is calculated to be 1612.87W, and with it added the heat loss is reduced to 542W, saving 33.61% of the heat loss.
