摘　　要：对国内直接空冷机组冷端乏汽节能减排技术进行了优缺点分析。结果表明:夏季,乏汽利用技术还有待提高;冬季,乏汽利用技术效果比较显著,其中以热网凝汽器回收乏汽和蒸汽喷射泵回收乏汽技术最好,投资少,节能减排效果明显。An analysis was conducted on the advantages and disadvantages of energy saving and emission reduction technologies for cold end exhaust system of domestic direct air-cooling units. Results show that the exhaust steam application technology has to be improved in summer. But it presents remarkable effects in winter, in which the waste heat recovery technologies by the way of heating network condenser and steam jet pump are proved to be the most advanced ones, featured by low investment, and high energy saving and emission reduction effects.
