Title: Combustion control method in incineration plant with boiler
Inventor: KOBAYASHI YOICHI
IPC: F23G5/50
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To achieve a stabilization and an efficiency in the generated output of electric power by stabilizing the boiler outlet pressure and the flow rate of steam. SOLUTION: A boiler pressure process value PPV (t) at a boiler outlet is measured cyclically and a pressure set value is corrected according to the deviation between the pressure process value and a pressure set value PSV (t) to obtain a corrected pressure set value PSV (t)'. The corrected pressure set value is supplied to a boiler pressure adjusting meter 2 in stead of the pressure set value and based on the value, the boiler pressure adjusting meter generates an output for adjusting manipulated variables K (t) such as number of revolutions of a dust feeder to adjust the amount of a fuel to be supplied to an incinerator. The correction of the set value is executed by performing a model forecasting control based on a model such as ARX model previously generated using the pressure set value of a boiler at the boiler outlet as input and the pressure process value as output.  A more proper control is possible by correcting the coefficient of the model using the corrected pressure set value and the pressure process value obtained by the measurement.

Abstract: PURPOSE:To eliminate the erroneous measurement of a function test while making it possible to remove the pellet inferior to pressure resistance of a gate oxide film in a wafer check stage and to enhance yield, by irradiating a MOS semiconductive apparatus with light after a voltage stress test and performing the function test of each specification. CONSTITUTION:Voltage of about 10V is applied from the input and output terminals of a MOS semiconductive apparatus, for example, a dynamic RAM to impart voltage stress to the MOS transistor and capacitor of each memory cell and the pressure inferiority of a gate oxide film is inspected. Next, the irradiation of light is performed, for example, by lighting the lamp 2 of a tester for 2-3sec and the charge charged by a voltage stress test is discharged to the capacitor of the boot strap circuit of the dynamic RAM. Thereafter, light is turned OFF and the function test of each specification of the dynamic RAM is performed by a tester. Because the voltage stress test is performed at first, the chip inferior to pressure resistance of the gate oxide film can be removed in a wafer state and, therefore, assembling yield is enhanced.
