摘要: Ferric sulfate is used as an additive in biomass combustion to convert the released potassium chloride less harmful sulfate. The decomposition of ferric studied a fast heating rate thermogravimetric analyzer and volumetric reaction model proposed describe process. yields sulfur oxides from under boiler conditions are investigated experimentally, revealing distribution approximately 40% SO3 60% SO2. combined with detailed kinetic gas-phase KCl sulfation K2SO4 condensation simulate by addition. simulation results show good agreements experiments conducted grate-firing reactor. indicate that main contributor effectiveness addition sensitive applied temperature conditions. © 2013 American Institute Chemical Engineers AIChE J, 59: 4314–4324,
