Thermodynamics and Energy


A Note on Heat Multiplication Factor

Authors: Radhakrishnamurty Padyala

Kelvin, one of the founders of thermodynamics, proposed an economical, thermodynamic method to heat houses. The method employs a combination of two Carnot heat engines. One engine runs in clockwise direction while the other runs in counterclockwise direction. This combination is claimed to provide much more heat into the house for a given amount of fuel used, compared to that obtained through burning that fuel inside the house. The ratio of the two heats, one obtained by Kelvin’s method and the other obtained by the burning the fuel inside the house, is known as heat multiplication factor (HMF). This factor could theoretically be quite high (a typical calculation gives more than a factor of 6). We show in this note that Kelvin’s method is fallacious - it is impossible to get any more heat by using Kelvin’s method than the heat that could be obtained from combustion (burning) of the fuel.
