摘要： PURPOSE:To measure the cumulative amount of powder transported to individual destinations even if destinations are changed for each batch. CONSTITUTION:A load cell 8 measures the weight of powder stored in a transmitter 4 and inputs the measured weight to a maximum value holding circuit 9. The circuit 9 always holds the latest signal and outputs the signal to adder circuits 14a and 14b. A first logic circuit 12 outputs a reset signal 13 to a memory 11 when both carrying-out valves 7a and 7b become idle. A second logic circuit 15 outputs an integration commanding signal 16a or 16b to the adder circuit 14a or 14b corresponding to either one of the valves 17a and 17b when the valve 7a or 7b becomes idle. Upon receiving the signal 16a or 16b, the circuit 14a or 14b integrates the amount of powder transported to each destination by adding weight signals stored in the memory 11 to the integrated value until the preceding time.

摘要： PURPOSE: To measure a drum level accurately regardless of operation or stoppage in a drum level detector which is attached to a steam and water drum type boiler to measure the water level of the boiler. CONSTITUTION: A condensing pot 4 is connected to an upper steam layer 1a of a drum 1 for detecting a drum level through a horizontal piping 5. Condensed water in the condensing pot 4 is taken out through a third horizontal piping 6 from the bottom surface of the condensing pot 4 to radiate heat sufficiently with the third horizontal piping 6 so that the temperature of the condensed water is lowered almost to the temperature of atmospheric air when flowing into a vertical piping 8. Thus, a hydrostatic head of the vertical piping 8 can be constant through the operation and stoppage of a boiler thereby making possible measuring of the drum level accurately regardless of the operation and stoppage.

摘要： PURPOSE:To increase utilization efficiency of fuel, and eliminate danger by exhaust gas by mixing inactive gas into fuel gas to be supplied. CONSTITUTION:Fuel gas H2 mixed with inactive gas N2 is supplied to a fuel layer 3 of a power generation furnace 4. The quantity of the fuel gas H2 is thus decreased by the quantity of the inactive gas N2 mixed, so a ratio of H2 of fuel gas to react to the quantity of the supplied fuel gas H2 is increased. Utilization efficiency of the fuel gas H2 can thus be increased, and running cost can be decreased. Because concentration of residual fuel gas H2 in exhaust gas is also decreased, danger by the exhaust gas can be eliminated.

摘要： PURPOSE:To prevent a sudden change in a model output at the time of switching a parameter of a linear model, and to improve the control performance, by installing a variation rate limiter for limiting a variation rate of an input of an integrator, in front of the integrator of the final stage for constituting a part of the linear model. CONSTITUTION:A variation rate limiter 3 for limiting a variation rate of an input of an integrator 4 is installed in front of the integrator 4 of the final stage. Therefore, when the variation rate of the variation rate limiter 3 is set in advance to the maximum variation rate value within a range in which modeling can be executed correctly at the time of a regular operation of a process being a controlled system, a control output is not brought to a sudden change exceeding a variation rate by which the process can be varied, even at the time of switching of a parameter 5 or a parameter 6 of a linear model by a model switching deciding circuit 7. Accordingly, an abnormal sudden change of a model output is prevented, and an output of the model moves smoothly. In this regard, the variation rate limiter 3 applies a limit to a variation rate of an input of the interrator 4, and sets the variation rate in advance to the maximum variation rate value by which a correct model output can be obtained at the time of a regular operation of the process being the controlled system.

摘要： PURPOSE:To minutely adjust a heat-exchange mediums of respective units to respective reference flow quantities by calculating the optimal distribution quantity of the heat exchange quantity with respect to a unit from the external condition and maintenance of a high controllability. CONSTITUTION:The requested heat exchange quantity is calculated from signals from a B gas transmitter 9, a B gas flow quantity transmitter 10, an exhaust gas temperature transmitter 11, and an exhaust gas flow quantity transmitter 12 by use of a function 13. By use of a signal from the function 13 the reference flow quantities with respect to respective units are set by functions 14A and 14B. The flow quantities are determined so that respective units are prevented from utilized in a region where the controllability is poor and the negative pressure operation is not carried out. The reference flow quantities are added to signals from water level deviation adjusting meters 7A and 7B of an evaporator. The opening degrees of circulating water control valves 4A and 4B are controlled by the adding signals.
