A method for regulating the load in a thermal engine having a power generator in order to keep the voltage or the frequency at the terminals of the power generator constant during load changes using constantly even power usage. Load regulation during load changes by maintaining a constant voltage or frequency in the terminals of the power generator, an electronic system determining the difference between maximum power capacity and present electrical load and this difference being conducted back to the thermal energy process as high-temperature heat by a variable load resistor.

Method for load regulation in a thermal engine having a power generator

A thermophotovoltaic generator having a solid body located in a combustion chamber of a burner, with the surface of the solid body being excited to a state of radiation by an air-fuel mixture that is supplied by a delivery unit to the burner, where it combusts, and the radiation strikes a photocell, which then generates electrical energy; and having an exhaust pipe discharging the hot combustion gases from the combustion chamber. A premixing chamber is closed from the combustion chamber to the outside by a porous solid body, the photocell is positioned opposite the porous solid body and upstream from the latter in the premixing chamber, a reflector is located downstream from the solid body and opposite the latter outside the premixing chamber so that it reflects the radiation produced by the combustion of the air-fuel mixture on the solid body in the opposite direction from the combustion gases flowing to the photocell, and the air-fuel mixture is delivered by the delivery unit to the premixing chamber so that the non-combusted air-fuel mixture flows around the photocell from behind, thus cooling it.
