摘要： PURPOSE:To permit to restore an appropriate air-fuel ratio within shorter time for the rapid increase of the combustion volume in the incinerator by a method wherein a differential value with respect to time for an internal pressure in the incinerator is seeked for, by which the basic operating volume is revised and composed, and based on that data the operating panel for adjusting air volume is operated. CONSTITUTION:PV01, an output concerning the furnace internal pressure sent from a furnace internal pressure transmitter 15, is sent to a differential computing element 21, to which a differential computing is made, and its differential value is transformed into signal y2, which is allowed to be sent to an adder 23 only for the case that the furnace internal pressure is varied to the positive side. In the adder 23, MV12, an output operating signal computed from an oxygen concentration contained in the combustion exhaust, and the said signal y2 are composed, which enable to actuate SV03, the setting value of the secondary air adjusting gage 26, variable. A flow rate of the secondary combustion air 8 is detected by a flow detector 24, which is compared with the setting value SV03 by the operating signal MV03, that is able to actuate a damper 10 to control the secondary air flow rate. In this controlling process, the setting value SV03 is made variable by the signal MO02 from the adder 23, and the cascade control is applied to the secondary air flow rate.

摘要： PURPOSE:To surely prevent the furnace pressure from becoming a positive pressure in an incinerator of urban rubbish etc. by determining whether the detected furnace pressure is higher or lower than the set value, and, when the detected value is higher than the set value, making the gain of the control system larger than that gain which is obtained when the detected value is lower than the set value. CONSTITUTION:The furnace pressure of an incinerator 1 becomes the output PV1 via a pressure transmitter 10 and a primary delay filter 15. By a subtracting unit 16, the difference from the set value SV of a PID adjusting unit 11 is determined. By an input compensation nonlinear arithmetic unit 17, when SV PV1 is selected to output PV3. In response to the output PV3, the PID computation is conducted in the PID adjusting unit 11 to output MV1, and the output MV0 is outputted via an adding unit 20. As the actuating output MV0 has become larger when SV PV1, the actuating speed of the damper 4 is made higher by the output MV0, the furnace pressure is promptly prevented from being increased to become a positive pressure.
