Herein we disclose an apparatus, comprising: an air feed; a fuel feed; a combustion zone, capable of mixing and combusting air and fuel therein; a temperature sensor positioned within the combustion zone, capable of measuring the temperature of at least one point within the combustion zone; and a control system, comprising: a processor to which the temperature sensor is capable of reporting the measured temperature; and an air flow adjustment apparatus controlled by the processor and capable of adjusting the flow rate of air to the combustion zone in response to the reported temperature. We also disclose a reformer, a power plant, and a fuel cell comprising or associated with the apparatus. In addition, we disclose a method of maintaining the temperature of at least one point within a combustion zone within a desired temperature range, comprising: specifying the upper bound of the desired temperature range; feeding air and a fuel to the combustion zone, wherein the air is fed at an air feed rate, the fuel is fed at a fuel feed rate, the amount of air and the amount of fuel present in the combustion zone define an oxygen to fuel ratio ("O/C ratio"), provided the O/C ratio is greater than the stoichiometric O/C ratio; measuring the temperature of the at least one point within the combustion zone; and increasing the air feed rate, if the temperature of the at least one point within the combustion zone is greater than about the upper bound of the desired temperature range, provided the O/C ratio remains greater than the stoichiometric O/C ratio. |
