Abstract
InvestigationonHg emission characteristics undercoal and biomass co-firing conditions is of great significance.Two sorts of coal were blended with two sorts of biomass at 95∶5,90∶10 and 85 ∶15 mass ratios,and the combustion experiments were conducted at 1250 ℃ in a high temperature electrical reactor.The gaseous Hg contents in the flue gas of different conditions were measured.The Hg contents and Hg emissions of unit calorific value of the blended fuels were calculated.The results indicate that the ratio of Cl to Hg of the fuel increases after blending biomass.And the increase of biomass blend ratio leads to increased Hg2+ratio and decreased Hg0 and total gaseous Hg ratios for coal 1; while the gaseous Hg ratio for coal 2 decreases first and then increases with the increase of biomass; after adding biomass,under the condition of unit calorific value,Hg2+emission increases,Hg0decreases,and total gaseous Hg emission decreases; for coal 2 that adding cotton stalk,when the blending ratio is 15％,the total gaseous Hg emission of unit calorific value is higher than that of the raw coal.关键词
