Abstract
This paper reports on the implementation of two-colour optical pyrometry to measure the distribution of surface temperature of a burning black liquor droplet in a flat flame environment. The black liquor was burned in the flame provided by the flat flame burner at two flame conditions, fuel lean (Øbg = 0.8), and fuel rich (Øbg = 1.25). Two identical digital singlelens reflex (SLR) cameras were used to allow the simultaneous measurement of the surface temperature and particle size. This provides an opportunity for more reliable measurements of surface temperature for black liquor than has previously been available.
