把脉动燃烧技术与回热式回收装置结合可以使得燃烧系统比仅用回热烧嘴更为高效。生产中的几个应用实例(实现了燃料节省)在该文中得以详述。在美国,热处理炉每年大约消耗了200×10~(12)Btu(英国热量单位,1Btu=252卡)的能量。在许多情况下,特别是更小的热处理炉,热回收还不实用。这样热效率就很低。过去,由于能源成本低,以及回收设备的投资高而造成的收回成本时间太长的原因,余热的回收在经济上还没有多少吸引力。可是,八十年代早期,热回收技术开
The combination of pulsating combustion technology and regenerative recovery can make the combustion system more efficient than using a regenerative burner alone. Several application examples in production (fuel savings realized) are detailed in this article. In the United States, heat treating furnaces consume about 200 × 10-12 Btu (British thermal units, 1Btu = 252 cards) annually. In many cases, especially smaller furnaces, heat recovery is not practical. This thermal efficiency is very low. In the past, the recovery of waste heat was not economically attractive yet due to the long recovery costs due to low energy costs and high investment in recovery equipment. However, heat recovery technology was started in the early 1980s
