针对油气行业使用的水套加热炉在实际运行中存在水浴温度较低的现象,利用水套加热炉换热模型分析了其水浴温度较低的原因,给出了提高水浴温度的解决方案:在水套加热炉设计过程中采取合理的换热管束换热面积,使水浴温度尽量达到理论设计水平,实现水套加热炉的优化设计。提出利用水的沸腾时间衡量水套加热炉设计优化的标准,即在保证合适的换热管束的换热面积情况下,使换热介质水的质量达到最小,且其沸腾时间控制在0.5~2 h。优化措施能有效降低该炉型的制造和运行成本,达到节能减排的目的。(表2,图2,参9)
The water jacket heating furnace used in the oil and gas industry has the phenomenon that the water bath temperature is low during the actual operation. The reason why the water bath temperature is lower is analyzed by using the heat transfer model of the water jacket heating furnace, and the solution to raise the water bath temperature is given. The water jacket heating furnace design process to take a reasonable heat exchanger tube bundle heat transfer area, so that the water bath temperature as much as possible to achieve the theoretical design level, water jacket heating furnace to achieve optimal design. Proposed the use of water boiling time to measure the water jacket furnace design optimization criteria, that is, to ensure proper heat transfer tube bundle heat transfer area, the quality of the heat transfer medium water to a minimum, and the boiling time controlled at 0.5 ~ 2 h Optimization measures can effectively reduce the furnace manufacturing and operating costs, to achieve energy-saving emission reduction purposes.
