Effect of External Mineral Addition on PM Generated from Zhundong Coal Combustion
نویسندگان
چکیده
The effect of intrinsic metal mineral elements in the combustion process pulverized coal on formation and transformation mechanism PM was investigated a drop-tube furnace air atmospheres at 1200 °C, which laid solid foundation for control particulate pollutants. results show that reducing evaporation or generated PM1 aggregating to form PM1–10 particles bigger than 10µm can reduce emission process. amount PM0.2, PM0.2–1, PM1–2.5 PM2.5 produced by raw coal-carrying Mg are reduced 36.7%, 17.4%, 24.6% 21.6%, respectively. PM10 is almost unchanged. addition increases viscosity submicron effectively, making it easier aggregate bond together ultra-micron particles. PM1–2.5, Ca 36.3%, 33.0%, 42.8%, 38% 17.7%, adding compounds better Mg. Fe 15.6%, 16.2%, 31.1%, 22.4% 5%, While production PM2.5–10 increased from 0.17 mg/g 0.34 mg/g, clear significant fraction during transformed into After comparing matter Mg, Fe, shows these three effectively ash melting point, so combustion, part sub-micron particles, easy remove.

CO2 Gasification Reactivity of Chars Derived From Zhundong Coal
Coal gasification with carbon dioxide is a process for generating clean gaseous fuels and relieving greenhouse effect. Zhundong coal has high alkali and alkali earth metals (AAEMs) content, medium volatile and low ash in nature. Isothermal CO2 gasification of char derived from Zhundong coal (R-char) and char from acid washing R-char (AR-char) are performed in thermo-gravimetric analyzer (TGA). ...
متن کاملMercury from Coal Combustion
A 1997 study in Minnesota indicated a relationship between mercury deposition trends and regional coal combustion (as well as other possible sources) spanning a period of two centuries (Engstrom and Swain 1997). Sediment core sampling from rural lakes in eastern Minnesota indicated a growth in mercury deposited from the air since the first half of the 1800s, with the amount peaking in the 1960s...
