Effects of Flue Gas Internal Recirculation on NOx and SOx Emissions in a Co-Firing Boiler
Volumetric combustion has been developed to realize a high substitution ratio of biomass in co-firing boilers, which features an intensive flue gas internal recirculation inside furnace. However, the characteristics of NOx and SOx emissions in large-scale boilers with volumetric combustion were not fully clear. In this paper, an Aspen Plus model of volumetric combustion system was built up base...

متن کاملThe thief process for mercury removal from flue gas.
The Thief Process is a cost-effective variation to activated carbon injection (ACI) for removal of mercury from flue gas. In this scheme, partially combusted coal from the furnace of a pulverized coal power generation plant is extracted by a lance and then re-injected into the ductwork downstream of the air preheater. Recent results on a 500-lb/h pilot-scale combustion facility show similar rem...
متن کاملPILOT-SCALE NOx AND SOx REMOVAL FROM BOILER EMISSION USING RADICAL INJECTION AND CHEMICAL HYBRID PROCESS
The pilot-scale NOx and SOx simultaneous removal from boiler emission was performed using radical injection and chemical hybrid process. The radical injection is often called as indirect plasma (or remote plasma) and air radicals are produced at room temperature with less than 1/10 of the flue gas flow rate. The flue gas from the boiler was in the range of 450~1,470 Nm/hr, the gas temperature o...
متن کاملUsing bromine gas to enhance mercury removal from flue gas of coal-fired power plants.
Bromine gas was evaluated for converting elemental mercury (Hg0) to oxidized mercury, a form that can readily be captured by the existing air pollution control device. The gas-phase oxidation rates of Hg0 by Br2 decreased with increasing temperatures. SO2, CO, HCl, and H2O had insignificant effect, while NO exhibited a reverse course of effect on the Hg0 oxidation: promotion at low NO concentra...
