摘要：A review was undertaken of all the tests of indoor air pollution from unventilated heating apparatus carried out at our institute since 1896. Fukuhara et al. (1941) found that the CO concentration in the flue gas from a briquette stove was 0.304% and that the CO generation rate of the briquette stove was 10.34 L/h. Shoji et al. (1942) found that the use of oval briquettes raised CO concentration to a maximum of 0.3% and that the use of a briquette brazier raised indoor CO concentration to 0.03-0.06% (300-600 ppm) (air exchange rate: 1 L/h, volume of room: 12m3). Watanabe et al. (1966) found that the use of a convection-type kerosene heater raised CO concentration to 25ppm and NO2 concentration to 1 ppm. Miyazaki et al. (1979) found that the NO2 generation rate of the convection-type kerosene heater was 4-5 times that of the radiation-type kerosene heater and that the CO generation rate of a used radiant-type kerosene heater was twice that of a new one. Miyazaki (2005) found in the chamber test that the generation rate of the kerosene fan heater was 2.5 times that of the radiation-type kerosene heater for NO2 and 5.6 times for NO.
