蓄熱式COG燃燒器應用於盛鋼桶加熱爐

Energy and Environment Research Laboratories, Industrial Technology Research Institute

摘要


蓄熱式燃燒器靠著蓄熱體與燃燒空氣的直接熱交換,在1200℃的爐溫時,可將排氣溫度降至約250℃,可利用的燃燒空氣溫度則提升至800℃以上,如此可有效地回收熱能,COG氣體其熱值大約為NG的一半但因燃燒所需之空氣的升溫可擴大火焰穩定範圍與空氣與燃料可燃比之範圍,而其切換燃燒的方式亦可提高燃燒區域的平均熱通量也可加強爐內的均溫性。本技術目前運用在盛鋼桶預熱台,連續式加熱爐都有十分顯著的節能效果。

Regenerative combustion technology uses honeycomb-type regenerator to exchange and recover heat with flue gas directly. The flue gas temperature can be down to 250℃ and the combustion air temperature can rise to 800℃ when the furnace temperature is 1200℃. Regenerative combustion technology can save fuel and also enhance the flame stability of combustion with Coke Oven Gas (COG.) The reciprocal firing also enhances the total heat flux and the uniform temperature for furnace. The Regenerative combustion technology is used in Ladle furnaces and heating furnaces so far that can achieve more energy saving.
