摘要

提高热交换器的性能是该行业研究人员和工程师的主要目标之一。本文针对壳管式换热器在污垢阻力、进口温度和流体流速等对换热器性能影响最大的因素影响下的效率进行了实验研究。本研究采用31.24型试验设计方法,共48次试验,3次重复。考虑以下因素:原油流体和TEG流体的入口温度和流量在两个水平上,污垢阻力在三个水平上。通过回归分析,建立了基于影响变量的效率数学模型。允许从最优中选择响应面和等值线图,并预测参数的行为。随着污垢阻力的增大、进口温度和流量的降低,其效率显著降低。

Experimental and statistical analysis on the effects of fouling and effective parameters on performance of heat exchanger
Increasing the performance of heat exchangers is one of the main objectives of researchers and engineers in the industry. In this paper an experimental work is carried out aiming at modeling the efficiency of shell and tube heat exchanger under the influence of the most contributing factors on performance as fouling resistance, the inlet temperatures and the flow rate of the fluids. An experimental design method of type 31.24 was used for the studies, requiring 48 tests with three repeats. The following factors are taken into account: the inlet temperature and flow rate of crude oil fluid and TEG fluid on two levels, and the fouling resistance on three levels. Regression analysis was produced a mathematical model for the efficiency based on the influential variables. The response surface and contour plots were allowed the selected from the optimum and predicted the behaviors of parameters. The effectiveness decreases considerably with the increase in fouling resistance and the decrease of inlet temperatures and flow rates.
