Abstract: A logic circuit provided with first and second cross-coupled NAND/NOR gates and third and fourth cross-coupled NAND/NOR gates. The second NAND/NOR gate is arranged to have a delay of output variation longer than that of the first NAND/NOR gate. A desired logic input signal is applied to one input of the first NAND/NOR gate. A first clock pulse is applied to the first and second NAND/NOR gates. A second clock pulse of opposite polarity to the first clock is applied to the fourth NAND/NOR gate. The output of the first NAND/NOR gate is coupled with the input of the third NAND/NOR gate.

Abstract: Disclosed is a furnace whose NOx emission may be reduced to a minimum degree so far unattainable in any prior art furnaces by optimumly controlling the ratio of exhaust gas mixed with the combustion air to be supplied to the burners to the exhaust gas to be mixed with the two-stage combustion air which is admitted through air nozzles into the combustion chamber and also by optimumly controlling the distribution of the two-stage combustion air in the combustion chamber depending upon the operating conditions. The present invention may be applied to any types of furnaces.
