Abstract:This study aims to integrate a thermophotovoltaic system into the combi boiler as gas-fired combi boilers are widely used in both the individual heating system and the preparation of domestic hot water. For this purpose, the numerical investigation of the thermophotovoltaic system integrated into the combi boiler is investigated in this study. Firstly, a TPV system model has been designed for the combustion chamber of the combi boiler. Then, the temperature of the combi boiler’s combustion chamber has been determined by operating the combi boiler at the minimum and maximum heating power. Numerical analyses have been done with these temperatures. Finally, the emitter thickness, the distance between the filter-TPV cell, the distance between the emitter-TPV cell and the filter thickness have been optimized in the TPV system model. Consequently, the optimum thickness of the emitter, the optimum distance between the filter-TPV cell, the optimum distance between the emitter-TPV cell and the optimum thickness of the filter have been determined as 20 mm, 1 mm, 34 mm and 4 mm, respectively. With this optimization, the electric power density of the TPV system model varies between 68,97 W/m2 / 515,66 W/m2 for the determined temperatures of the emitter surface. In addition, the TPV system model has an efficiency varying between 1,05% and 2,56%.
