Features of the Heating System of the House-Museum of K.G. Paustovsky in Tarusa

The House-Museum of the writer Konstantin Georgievich Paustovsky in Tarusa (Kaluga region), the history of its acquisition and the interior of the house, the walls of which are decorated with paintings by the youngest son of the writer artist A.K. Paustovsky, are described. It is noted that the peculiarity of Paustovsky’s house is that round-shaped ovens in a metal casing made of galvanized steel painted black were used for heating, and not just a traditional dutch oven. The thermal efficiency of such ovens is ensured by their constructive solution, the presence of an internal chamber and a chamber with a lifting well, through which the heated gas rises up between two parallel operating lowering wells, as well as a gradual decrease in the thickness of the wall, starting from the fireplace. The calculation of the amount of heat supplied from the oven to the room, developed by the authors, is given, which takes into account the components of the convective radiant heat transfer of the oven surface. The average coefficient of convective heat transfer is determined based on the solutions of criterion equations for the turbulent mode of air movement near the oven surface. The radiant heat exchange coefficient of a cylindrical oven in a black iron casing is determined based on the solutions of the equations of radiant heat transfer between the oven and the surfaces of the room. This made it possible to obtain the value of the average heat transfer of the oven. The comparison of average heat transfer values showed that with a one-time heating with a period of 24 hours, 1,5 times more heat enters the room from a cylindrical oven in an iron casing, painted black, than from a cylindrical oven with a galvanized iron casing.
