Abstract

PURPOSE: To enable to rapidly and simply perform measurement with good accuracy, by measuring emitting quantity of smoke in combination with a measuring apparatus of intensity of transmitted light and a piezobalance weight gauge.
CONSTITUTION: Intensity of transmitted light in smoke emitting vessel 1 is measured by the light source 2 and the sensor 3. The exit 9 of the vessel 1 is connected with the massive particle collector 14, electric dust precipitator 15 and piezobalance weight gauge 16 through the piping 10 and circulation for the vessel 1 is carried out through the pump 18. By said construction, absorbance is found by the ratio between the transmission intensity of light at the time of no smoke in the vessel 1 and the intensity after emitting smoke. Further, weight of the smoke is found from that of the smoke dust by the gauge 16. Emitting quantity of the smoke is determined by the value at the time when the maintaining ratio of absorbance is zero, because the relation between the absorbance and the weight of smoke is nearly straight line. Hereby, emitting quantity of the smoke is found without depositing the whole particles and rapid and highly accurate measurement is carried out.
