Combustion experimental study of reed black liquor (RBL) droplets and particles in fluidized bed

摘要

The experiments were carried out to investigate combustion characteristics of RBL droplets (RBLD) and RBL particles (RBLP) in fluidized bed. The combustion experiments were focused on the influence of six different bed temperatures in the ranging from 530 to 780°C on gas production rates, yields of product, carbon and hydrogen conversions, releases of Na, K and Cl and emissions of NO_x and SO_2. The experiments results indicate that the combustion behaviors of RBLD and RBLP mainly depend on bed temperatures. The conversions and emissions have linear relation with bed temperature, respectively. And denitrification and desulfurization processes must be had during incinerate RBL in industry application.
