Abstract

The droplet heat and mass transfer processes are important for liquid spraying technologies, which were investigated when applying the theoretical and numerical modelling and experimental methods. In this work, results of experimental research on the heating of water droplets in purified biofuel flue gas were presented and analyzed. In experimental investigation, the purified biofuel flue gas is replaced by additionally humidified airflow. The experiment methods and results processing are discussed and provided. Impact of air heating and additional humidification was estimated. While heating and additionally humidifying the air flow was focused on boundary conditions in condense economizers, when the flue gas temperature is 20-100°C and water vapor volume fraction is 0-0.2.
