以高效传热元件——热管组成的热管换热器已在余热回收中得到日益广泛的应用,并取得了明显的节能效果。广泛应用的水-铜热管和水-钢热管的制造工艺已趋于成熟。在我国,热管节能技术正处于不断完善提高和逐步推广应用的阶段。目前我国研制的热管换热器,大部分用于烟道气的余热回收。烟道气从燃料的品种来分,可分为燃煤的烟道气、燃烧重油的烟道气、燃烧气体燃料的烟道气;从炉子的结构和用途来分,
The heat pipe heat exchanger composed of an efficient heat transfer element and a heat pipe has been widely used in waste heat recovery and has achieved obvious energy saving effect. Widely used water - copper heat pipe and water - steel heat pipe manufacturing process has matured. In our country, heat pipe energy-saving technology is in the stage of continuous improvement, improvement and gradual promotion and application. At present, China’s development of heat pipe heat exchanger, most of the waste heat for flue gas recovery. Flue gas from the fuel species to points, can be divided into coal-fired flue gas, heavy oil combustion flue gas, combustion gas fuel flue gas; from the furnace structure and use to points,
