摘要： PURPOSE:To detect the clogging of a burner by comparing scatter in variations in luminance and the coefficient of transmissivity with a threshold value. CONSTITUTION:A variation C in luminance is sought by making comparison calculation with a plurality of standard images after seeking the temporal average luminance Bij which is given by measuring and averaging luminances Aijk (for example, the luminances of red(R) components) for respective image elements i, j by sampling in N times carried out for a certain time division in a time range of constant load after the treatment to make a standard image. The sought variation C in the luminance is compared with a threshold value which is experimentally sought beforehand, and if it is larger than the threshold value, the clogging of burner is judged and it is taken as a first judgement reservation signal. As for transmissivity tau a statistical data for transmissivity under stable combustion (ordinary combustion) in a time range with a constant load (average value m, variance value sigma) is beforehand made to seek the degree of scatter f(tau). The degree of scatter f(tau) of the sought transmissivity tau is compared with the threshold value, for example 3sigma, which is experimentally sought, and if it is larger than the threshold value, the clogging of the burner is judged, and it is taken as a second judgement reservation signal.

摘要： PURPOSE:To perform comparison with an excellent burning state readily by decomposing the output of the image obtained by photographing the flame of the burner of a furnace into the color components of three primary colors, and providing a high-temperature-area-rate operating circuit which receives red and blue signals and computes the area rate of the high-temperature part of the flame. CONSTITUTION:A flame-temperature-index operating circuit 25 receives the red and blue signals of a flame memory and computes the area rate of high temperature. The circuit 25 further receives the output of a high-temperature-area-rate operating circuit 20 and computes the temperature index of the temperature of the flame. A transmittance operating circuit 21 receives the red signal of the flame memory 7 and computes the transmittance of the flame. A low-luminance-area operating circuit 22 receives the red signal of the flame memory and computes the low-luminance area of the red component. A flame-transparency-index operating circuit 26 receives the outputs of the circuit 21 and the circuit 22 and computes the transparency index of the flame. A time-stability operating circuit 23 receives the green or red signal of the flame memory 7 and computes the time stability of the flame. An average- luminance-level operating circuit 24 receives the red signal of the flame memory 7 and computes the average luminance level of the flame. A flame-stability-index operating circuit 27 receives the outputs of the circuit 23 and the circuit 24 and computes the stability index of the flame. A diagnostic circuit 28 receives the outputs of the circuit 26 and the circuit 25, obtains the predefined individual-burner evaluating functions and outputs the result of the diagnosis of the burning state of the individual burner.

摘要： PURPOSE:To enable easy reregulation of a burner into an ideal combustion state by a method wherein when the burner is previously in a given combustion state, a ratio of the area of a given section to the area of all sections is determined, and an air flow rate, a fuel flow rate, and a recirculating gas amount are controlled so as to maintain the same ratio during operation. CONSTITUTION:Temperatures at points at the side of flame obtained by measurement are divided at intervals of a proper temperature step, for example, 10 deg.C to prepare a constant temperature line distribution diagram ranging from 1500 deg.C to 1200 deg.C. The area of each temperature section is determined, the areas are S1, S2, S3, and S4. In the case S0=S1+S2+S3+S4, regards a ratio between R1=S1/S0 and R2=(S1+S2)/S0, a value in the combustion state of each burner in a normal combustion state is previously experimentally determined. An air flow rate control damper 11, a primary air flow rate regulating damper 13, and a secondary air flow rate regulating damper 14, and a fuel injection valve 08, a recirculating gas flow rate control damper 10, and a burner recirculating gas regulating damper 12 are operated so that R1 and R2 are adjusted to respective values. The combustion state of each burner can be easily maintained in an excellent state.

摘要： PURPOSE:To detect the quantity of supply of air for burning which is supplied to each burner, by providing a converting means for converting the concentration of wet O2 of the air for burning into the concentration of dry O2. CONSTITUTION:An O2 concentration computing unit 121 is connected to an O2 sensor 52 measuring the concentration of wet O2 of air for burning, and it controls the sensor 52 while applying prescribed correction to a voltage signal corresponding to a measured concentration of wet O2. A Wet/Dry converter 125, which is connected to the computing unit 121, computes a gas component in a burning gas and the mixture ratio thereof from the concentration of wet O2 in the air for burning, the concentration of wet O2 in a burnt exhaust gas and burning composition, and converts the concentration of wet O2 of the air for burning into the concentration of dry O2. A flow velocity/ temperature compensation computing unit 131 is connected to a flow velocity sensor 71 measuring the flow velocity of the air for burning and applies temperature compensation to a measured value corresponding to the flow velocity obtained. By an output of the concentration of O2 (or the flow of the air) obtained from the sensor 52 (or 71) through each circuit, according to this constitution, the quantity of supply of the air for burning can be adjusted by applying a feed forward control to a block member or the like, and NOx in a burning gas can be lessened by conducting appropriate multi-stage burning.

摘要： PURPOSE:To expedite the substitution of gas, to improve the responsiveness of measurement and to enable the protection of a measuring electrode from thermal impact, by providing a gas channel from inflow to outflow of a gas to be measured which passes in the vicinity of the base end part of an oxygen sensor formed of a solid electrolyte. CONSTITUTION:A plurality of oxygen sensors 10 fitted to a main pipe 1 are set in the flow of a gas to be measured. The gas enters an internal space 21 through a filter 15 from gas inflow ports 24 provided in four spots of a filter cover 2 of a sensor 10, and the substitution of the gas is implemented by gas diffusion and thermal convection due to a difference in concentration of the gas, in a place from the internal space to a measuring electrode. The other part of the gas passes through a gas inlet-outlet port 25, a gas passage and a gas exhaust port 22 and is released outside. When a calibration gas is introduced through an introduction pipe 18, it is passed through an introduction port 20 and the inlet-outlet port 25 and filled up in the space 21. Since the space 21 is put in a state of positive pressure on the occasion, the inflow of the gas to be measured is prevented. Part of the calibration gas is brought into contact with the measuring electrode by pressure introduction. The other part of the calibration gas is exhausted from the exhaust port 22 through the gas passage at the time point where the space 21 is put in a state of negative pressure.
