Flus gas characteristics | White ash kiln flue gas temperature is low, generally around 140-220 ℃; flue gas water content is low, generally at 5%-8% (vol%); SO2 content is low, generally at <50mg/Nm3, but there are fluctuations; dust calcium content is extremely high, generally at around 60-80%. | High NOx content, glass melting process temperature up to 1500 ℃ or more, high temperature combustion generates a large amount of thermal NOx; change fire operation, flue gas volume and flue gas components fluctuate greatly; alkali metals, alkaline earth metals (Na salt, K salt, CaO, etc.) content is high, resulting in rapid loss of catalyst activity; small particle size of soot, strong adhesion and high corrosion, containing a variety of acidic gases (HCl, HF, etc.). | Coke oven flue gas temperature is low, higher than sintered pellets, generally around 200-260°C. The water content of flue gas is large, generally in the range of 12%-18% (vol%). Different fuels lead to different levels of NO content in coke oven flue gas, generally in the range of 300-1500mg/Nm3. SO2 content varies greatly from coke plant to coke plant. The SO2 content in coke oven flue gas is generally in the range of 50-800mg/Nm3. The dust content is low, generally in the range of 2O-50mg/Nm3. |
Product characteristics | The catalyst needs to meet the denitrification activity under low temperature; it needs to meet the resistance to sulfur poisoning under low temperature; it needs to meet the resistance to alkali (calcium) poisoning. | The diversity of fuels (using fuels such as heavy oil, natural gas, coal gas, petroleum coke, etc.) leads to large differences in the composition of flue gas pollutants; the catalyst needs to meet the denitrification activity at low temperatures; it needs to meet the resistance to sulfur poisoning; it needs to meet the resistance to alkali poisoning; it has the ability to resist corrosion of acid gases. | The catalyst needs to meet the performance of denitrification at low temperature; it needs to have the ability to resist sulfur poisoning at low temperature; it needs to have the ability to resist water poisoning at low temperature. |
