Paper Abstract

A method and its theory of measuring the total heat flow of hot equipment by two IR systems are set forth in this paper. One Of the IR systems includes a pyrometer with a hemispherical reflector and the other includes a pyrometer with a hemispherical absorber. These two IR systems are used to measure the surface temperature and emissivity of the hot equipment. Given the temperature of the relatively cold background and the height of the measurement point on the equipment surface, the total heat flow can be figured out easily. The measurement uncertainty of the method is less than 5% if the surface temperature and the emissivity of the hot equipment are greater than 200°C and 0.7 respectively.
