热管换热器是一种高效的余热回收装置,但由于应用在燃煤炉窑的烟气中容易积尘失效,所以一直未得到很好的应用。中国有色金属工业总公司长沙公司节能技术服务中心(湖南有色金属研究所)为湖南新化瓷厂2~#隧道窑设计研究的热管换热器于一九八七年八月一日正式投产运行,使用了振动和吹灰的方法,解决了换热器积尘问题。经一个多月的运行,换热效果良好,回收热量达35～40万千卡/小时。使该厂烘坯产量提高了三分之一,效益十分显著,为陶瓷行业推广应用热管换热器回收余热取得了新经验。
Heat pipe heat exchanger is an efficient waste heat recovery unit, but it has not been well applied due to the failure of dust accumulation in the flue gas of coal-fired furnaces. China Nonferrous Metals Industry Corporation Changsha Energy Saving Technical Service Center (Hunan Institute of Nonferrous Metals) for the Hunan Xinhua Coking Plant 2 ~ # tunnel kiln design and study of heat pipe heat exchanger on August 1, 1987 formally put into operation , The use of vibration and soot blowing method to solve the heat exchanger dust problem. After more than a month of operation, the heat transfer effect is good, recovering heat amounting to 35 to 40 million kcal / hour. So that the factory baked blank production by one-third, the benefit is very significant, for the ceramic industry to promote the use of heat pipe heat exchanger waste heat recovery has gained new experience.
