    摘要： PURPOSE:To cause a anti-earthquake automatic fire extinguisher or an alarm unit to be operated by a method wherein a cooperating body is arranged through an operating frame for operating an antiearthquake fire extinguisher device in response to a thermal deforming element and an engagement part to be engaged with the cooperating body is arranged near the thermal deforming element. CONSTITUTION:When a lack-of-oxygen condition is found and the temperature near the wick 1 guiding cylinder 2 and the wick 1 outer cylinder 3 is decreased due to a lack of oxygen in the combustion air, a displacement force of the bimetal 5 arranged at the upper surface of the core guiding cylinder 2 is utilized to cause the interlinking body 8 having an inverted L-shape at its extremity end to be rotated and the interlinking body 8 is disengaged from the engagement part, dropped due to a force of spring 10 or own its weight, the antiearthquake automatic fire extinguisher 7 is operated through the operating frame 9 arranged at a lower end of the interlinking body 8 and the fire is extinguished. In case that the antiearthquake automatic fire extinguisher device is set under a lack of oxygen, the interlinking body 8 is pushed up by a lock lever, the extremity end of an inverted-L shape of the interlinking body 8 is automatically rotated toward the engagement part under a rotating force of the compression spring 10 and so it can be set at the engagement part.

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.
