摘　　要：不用水蒸汽的大气式热力除氧法，是利用温度高于或等于１２５℃的余热，经表面式换热器将压力高于或等于０．４ＭＰａ的软水加热到１１０℃以上，软水进入除氧器后，因压力降低而沸腾，从而达到除氧的目的。采用此方法除氧，相当于将工艺余热的温度提高了３０～５０℃，节省了大量燃料，为企业中大量难以回收的１２５～１５０℃的低温热的利用开辟了新的途径。Atomospheric type thermodynamic deaeration without using steam method is that by using of waste heat at temperature equal or larger than 125℃ to heat soft water to above 110℃ at pressure equal or larger than 0.4MPa in surface heat exchanger.After soft water enters into deaertor,the soft water boiled caused by pressure drop,then obtained the goal of deaeration.Adopting this method is commensurate with the processing waste heat to increase 30～50℃.So that,a large numbers of fule are saved.A new way for using numerous low temperature(125～150℃) heat,which is difficult to recover in industry,is started in enterprise.
