Experimental Study On The Fouling Factor Of Helical Finned Tube

A semi-industrial experiment on fouling factor of helical finned tube bundle is done in a 75t/h boiler unit. Profiles of the fouling factor with different flue gas velocity are observed. It is found that the fouling factor of the experiment is much smaller than the recommended value by the former Soviet Union standard, which is widely used in China. And it is as the same order as the result of other researchers in China, which is resulted from lab. Discussions are made between the differences. Compared with the work of other researchers in China, the result of this article is more suitable.
