  • 摘要: 为了使应用高温低氧燃烧技术的加热炉达到高效节能、低污染物特别是低NOx排放的目的,采用计算机数值模拟优化设计了加热炉的蓄热式燃烧系统,并运用冶金反应工程学方法开发了成套技术.该技术在唐钢高速线材厂的实际应用表明:在热装钢坯条件下单位能耗为0.879 GJ/t,炉子热效率在67%以上,各蓄热室的排烟温度在160℃以下,NOx排放小于40×10-6(体积分数).

     

    Abstract: In order to achieve high efficiency, energy saving and low contamination emission for a reheating furnace with the high-temperature low-oxygen combustion technology, a regenerative combustion system of the furnace was designed by the way of numerical simulation, and a set of patent technologies was developed by the theory of metallurgical reaction engineering. An applied result of the patent technologies in Tanggang High-Speed Wire Mill indicated that the energy consume is 0.879 GJ/t, the thermal efficiency of the furnace exceeds 67%, the temperature of emission exhaust gas from the regenerator is below 160℃, and the NOx content in exhaust gas is less than 40×10-6 in voluminal fraction.
