In this paper, the D.D.C. experiments in a mono-tube boiler by a digital computer are reported. The test boiler used was a once-through mono-tube boiler with pressurized furnaces.The digital process control computer is installed instead of conventional analog controllers, and the boiler is operated by this Direct Digital Control device. The algorithm used in these D.D.C. experiments was a PID control, ratio control and feed forward control.From these experiments, the following results are obtained:1.The performance obtained by the D.D.C. system is good.2.An operator is able to change the control mode and adjust control constants easily, if it is necessary. So an operator can select the suitable control mode and constants during the boiler operation.3.D.D.C. system is stable, practical and accurate enough for the boiler operation.
