摘要:
能源的再回收与利用是目前节能和能源行业关注的焦点,余热锅炉是余热回收过程中最重要的部件,相关参数的优化与分析己成为现阶段余热利用研究的重点,参数优化的结果可为余热锅炉工程设计提供参考。文章基于2500 t/h水泥窑窑尾烟气工况,针对水和其他5种有机工质进行余热锅炉参数设计优化,并利用Matlab编程进行数据计算,对不同工质相同参数与同种工质不同参数分别进行换热性能及压降分析,探究烟气迎面质量流速、管间距以及换热管长对余热锅炉换热面积、烟气和工质侧压降的影响规律。结果表明:6 种工质按参数变化进行比较,其中水的换热面积最大;随着烟气质量流速和换热管长的增加,所需换热面积减小,而随着管间距增加,所需换热面积增加;在烟气侧压和工质侧压分别降低至50、1 kPa的条件下,换热面积最小的工质为庚烷,其值为183.3 m2。
Abstract:
Recycle and utilization of energy is currently the focus of energy conservation and energy, waste heat boiler is one of the most important parts in the process of waste heat recovery, related parameter optimization and analysis of the waste heat boiler has become the key point of the waste heat utilization, and parameters optimization results can provide reference for engineering design of waste heat boiler. This paper, based on 2500 t/h cement kiln preheater working condition of flue gas, water and other five kinds of organic substance in waste heat boiler design optimization of parameters, by using matlab programming for data calculation, analyzed heat transfer and pressure drop performance analysis respectively of the same parameters of different working medium as well as the different parameters with the same working medium, and investigated the influence of the flow rate, tube spacing and heat transfer tube length on the heat transfer area, flue gas and lateral pressure drop of the heat exchanger. The results show that compared with the change of parameters, the heat exchange area of water was the largest. With the increase of flue gas mass velocity and heat transfer tube, the heat transfer area reduces. However, with the increase of pipe spacing, the heat transfer area increases. Under the condition that the flue gas side pressure was reduced to 50 kPa and the lateral pressure of the work force was reduced to 1 kPa, the heat exchange area was the minimum quantity of industrial heptane, and its heat exchange area was 183.3 m2.
