Alkali sulfation during combustion of coal in a pilot scale facility using additives to alter the global sulfur to potassium and chlorine to potassium ratios

Due to the urgent needs reduce anthropogenic carbon dioxide emissions there is an increasing interest in use of alternative fuels. For this reason, a need for new knowledge on how design and adapt existing heat power plants biogenic waste-derived This work relates co-firing biomass coal sulfation alkali chlorides coal-fired flames doped with chemical additives. We aim examine global time scales chlorination based combustion experiments that were conducted 30-kW flame. Temperature, gas particle composition measurements conducted. Both modelling support apparent kinetics are fast flame it dominated entirely by presence SO2. The availability oxygen monoxide, or hydrocarbons, also critical sustain reaction cycle; low concentrations sufficient. industrial boilers implies sulfur addition, combination reburning, should constitute efficient strategy mitigate alkali-chlorination related high temperature corrosion.
