ABSTRACT:
A combustion control system for a furnace monitors the oxygen content, carbon monoxide content and temperature in the flue gas exhausting from the combustion chamber. These parameters are used to calculate total heat loss due to unreacted oxygen and the other excessive air components associated therewith, and carbon monoxide. Such heat loss calculations are continuously made and compared to determine whether total heat loss, oxygen related heat loss and carbon monoxide heat loss are increasing or decreasing. Depending upon the combination of increase and decrease associated with the various heat losses, the combustion air supply is increased or decreased. In this manner it is possible to minimize heat loss and maximize furnace efficiency even though the combustion characteristics of the combustion unit may change with time.
