摘要: Abstract The concentration of submicron particles, HCl and SO2 in the flue gas from combustion straw wheat, barley oil seed rape was studied by field measurements on two utility boilers. particles varies 75–2000 mg Nm-3 § mean diameter range 0.2 to 0.6 μm. principal constituents are potassium sulfhate chloride. composition depend content K, Cl S straw. These elements a great extent volatilized zone. A theoretical analysis indicates that particle conversion occurs during cooling homogeneous nucleation K2SO4 which act as condensation nuclei for subsequent KCl. It is found kinetics oxidation SO2, slow below 800°C, important chemical changes gas. can be approximately predicted assumption determined equilibrium sulfation reaction at 812±10°C.
