Mercury transformation and speciation in flue gases from

16 biomass burning. Mercury in coal, ores and other raw materials is released to flue gases 17 in the form of Hg0 during combustion or smelting in boilers, kilns or furnaces. 18 Decreasing temperature from over 800°C to below 300°C in flue gases leaving boilers, 19 kilns or furnaces promotes homogeneous and heterogeneous oxidation of gaseous

Mercury removal performance of brominated biomass

Feb 01, 2021 · Abstract. Brominated biomass activated carbon, with impactful gaseous mercury removal performance, has become a novel cost-effective and environment friendly alternative adsorbent for activated carbon. In this paper, the mercury removal behavior of brominated rice husk activated carbon (RHAC-Br) injecting was investigated in a simulated flue gas entrained-flow experimental system, a …

A review on methods of flue gas cleaning from combustion

Jan 01, 2014 · Flue gases and particulate from biomass combustion. The flue gas arising from combustion of biomass can be wet or dry depending on moisture content of biomass fuel used. Also the composition of flue gas varies mainly because of the type of biomass fuel and method of combustion adopted. Flue gas mainly has two parts, particulate matters and toxic gases.
