Methods and apparatus for regulating furnace combustion air flow are provided which measure a gaseous combustion product in furnace gas after combustion, generate a present signal responsive to the measurement and change flow rate of combustion air in response to the generated signal in a manner the same as flow rate was changed in response to a previously generated signal if the present signal relates to the previous signal in the manner the previous signal related to a signal ancestor thereto but change the flow rate of combustion air in response to th...
Apparatus for regulating flow of combustion air to a furnace thereby to maintain a relatively optimum fuel-air mixture for high combustion efficiency in response to a measured level of carbon dioxide in furnace gas after combustion thereof, comprising: a. gas analyzer for sensing relative level of carbon dioxide in furnace gas after combustion thereof and producing an electrical signal proportional to sensed carbon dioxide level; b. amplifier means, receiving said electrical signal from said gas analyzer, for boosting said signal to a second signal level...
