ABSTRACT:
In a system for combustion of fuel to produce heat in which there are alternate primary and secondary means to supply combustion air and in which the fuel flow is ratioed to the total air flow, the flow of fuel to the combustion chamber is controlled on shutdown of operation of the primary means for supplying combustion air by activating the secondary means for supplying combustion air and relaying a signal to the ratio controller which falsely indicates sufficiently low flow of air to the combustion chamber to cause an immediate reduction of flow of fuel to the combustion chamber to be within safe limits.
