宝能供热厂锅炉全年运行,为北京西站区域解决蒸汽需求,并服务热力厂周边区域8.6万m2建筑的冬季供暖需求.为节省资源,宝能供热厂回收烟气余热代替以往燃烧天然气所产生的部分热量,以满足供热厂周边建筑最大为4.90 MW的供暖负荷.为了在保证烟气余热回收效果的同时,解决设备被腐蚀的难题,选用先进改性聚合物材料,设计一款用于烟气深度冷凝余热回收系统的改性聚丙烯冷凝式换热器;并通过数值模拟的方法对换热器的设计进行结构性优化,从而满足工程应用上对于设备寿命长、故障率低、耐腐蚀以及换热性能优良的要求.
Design and numerical simulation optimization of heat exchanger for modified polypropylene
The boilers at the Baoneng Heating Plant operate year-round to meet the steam demand of the Beijing West Railway Station area and the winter heating demand of 86 000 m2 of buildings in the area surrounding the heating plant.In order to save resources.Baoneng Heating Plant recovers flue gas waste heat instead of part of the heat generated by burning natural gas in the past to meet the maximum heating load of 4.90 MW of the buildings around the heating plant.In order to ensure the effectiveness of the flue gas waste heat recovery and at the same time to solve the problem of corrosion of the equipment,this paper selects advanced modified polymer materials to design a modified polypropylene condensing heat exchanger for the flue gas deep condensation waste heat recovery system;and the design of the heat exchanger is structurally optimized by numerical simulation to meet the requirements of long life,low failure rate,corrosion resistance and excellent heat transfer performance.
