Abstract
Official abstract text for this publication.
A flame detecting system includes a flame sensor to detect light and a calculating device, in which the calculating device includes an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of flame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times, and in which a difference in sensitivity of individual flame sensors is corrected from sensitivity parameters related to a first flame sensor and sensitivity parameters related to a second flame sensor.
First claim

The invention claimed is: 1. A flame detecting system comprising: a flame sensor configured to detect light; and a calculating device, wherein the calculating device comprises: an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of a flame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times, and wherein the central processing unit is configured to obtain quantities of received light respectively from sensitivity parameters related to a first flame sensor and sensitivity parameters related to a second flame sensor, compute a ratio of the quantities of received light, and correct a difference in sensitivity of individual flame sensors. 2. The flame detecting system according to claim 1 , wherein using the ratio of the quantities of received light, a presence or absence of flame determination threshold related to the first flame sensor is multiplied by the ratio of the quantities of received light and the value obtained by the multiplication is used for a presence or absence of flame determination threshold related to the second flame sensor. 3. A flame detecting system comprising: a flame sensor configured to detect light; and a calculating device, wherein the calculating device comprises: an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of a flame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times, and wherein the central processing unit is configured to obtain quantities of received light respectively from sensitivity parameters related to a first flame sensor and sensitivity parameters related to a second flame sensor, compute a pulse width ratio based on the obtained quantities of received light of individual flame sensors, and correct a difference in sensitivity of individual flame sensors.
