摘要
通过热力计算基本公式分别对O2/CO2=30/70气氛与空气气氛下300MW锅炉的烟气及锅炉各项功耗效率、燃煤量的计算与对比分析。通过计算得出富氧燃烧的锅炉效率略有增加。富氧燃烧锅炉的烟气主要是CO2,CO2具有较大的比热,但是富氧燃烧的烟气量减少了很多,因此折合的烟气焓值减小,最终的综合计算,富氧燃烧的排烟损失比常规燃烧的排烟损失减小了。同时本文通过经济计算对PC、PC+MEA、O2/CO2三种方式下进行经济性分析。通过对供电成本和CO2减排成本的对比分析表明,富氧燃烧技术在CO2减排的应用中比MEA吸附技术更加经济。
The thermodynamic calculation of the basic formula in MW boiler flue gas and boiler of the power efficiency, the amount O2/CO2 = 30/70 calculation and comparison of the 300 of coal in the atmosphere and air atmosphere. A slight increase in calculated oxygen-enriched combustion boiler efficiency. Oxygen-enriched combustion boiler's flue gas CO2, COz larger than the heat, but the amount of oxygen-enriched combustion flue gas has decreased a lot, and therefore equivalent to the flue gas enthalpy is reduced, the final calculation, the emission of oxygen-enriched combustion reduce smoke loss than the conventional combustion exhaust gas losses.Through economic calculation and economic analysis on the PC, PC+MEA, in O2/CO2 three ways. By comparison of the cost of electricity and CO2 abatement cost analysis showed that the oxyfuel technology in the application of CO2 emission reduction technology is more economical than the MEA adsorotion.
