提出了碳化硅陶瓷管高温换热器管束辐射传热模型,管内“辐射—导热—对流”偶合传热理论分析及辐射强化传热措施,并进行了管内强化传热实验研究及现场工业窑炉生产试验。试验表明,使用本换热器可节能27%;并认为,主要控制热阻为管内不吸收辐射能的透明体常温空气一侧。因此,在高温下建议管内使用扭比系数大的麻花铁或扁钢、十字格、星形格等结构的内插件以作为强化管内辐射传热的措施。 The radiation heat transfer model of tube bundle of silicon carbide ceramic tube high temperature heat exchanger, the theory of coupled heat transfer in tube and the heat transfer enhancement by radiation in the tube were put forward. The experiment of heat transfer enhancement in the tube and field industry Kiln production test. Tests show that the use of the heat exchanger can save 27%; and that the main control of heat resistance is the tube does not absorb radiation transparent body temperature air side. Therefore, at high temperature, it is advisable to use plugs, such as twist iron or flat steel, cross grids and star grids with large torsional ratio coefficient, as the measures to intensify the radiative heat transfer in the pipe.
