Black liquor is the fuel of Kraft recovery boilers. It is sprayed into the furnace of a recovery boiler through splashplate
nozzles. The operation of a recovery boiler is largely influenced by the particle size and particle size distribution of black
liquor. When entrained by upwards-flowing flue gas flow, small droplet particles may form carry-over and cause the
fouling of heat transfer surfaces. Large droplet particles hit the char bed and the walls of the furnace without being dried.
In this study, particles of black liquor sprays were imaged using a high-speed infrared camera. Measurements were done
in a functional recovery boiler in a pulp mill. Objective was to find a suitable wavelength range and settings such as
integration time, frame rate and averaging for the camera.
