Abstract
An apparatus (1) is disclosed for controlling oxidation of a fuel in an oxidation source (2,3). The apparatus includes photovoltaic means (5) for receiving electromagnetic radiation (6) from the oxidation source and for producing electric power having a given electric power magnitude. An oxidation control (8, 1A, 1B, 288, 325) is coupled to, and driven, by, the photovoltaic means for controlling the oxidation. The oxidation is adjusted when the electric power is less than the given electric power magnitude. Oxidation may also be adjusted when a hazardous gas is detected. The apparatus (1A) may be used to power various electronic circuits. The apparatus (1B) may also be used to maintain the efficiency of the combustion source. A novel arrangement (248) for operating a fuel control valve is also disclosed. An apparatus (418) for controlling a portable heater is also disclosed.
