Ash deposits - Initiating the change from empiricism to generic engineering. Part 2: Initial results
The goal is to develop and use calculations and measurements from several engineering disciplines that exceed the demonstrated limitations of present empirical techniques for predicting slagging/fouling behavior. In Part I of this paper, general relationships were presented for assessing effects of deposits and sootblowing on the real-time performance of heat transfer surfaces in pilot- and commercial-scale steam generators. In Part 2, these concepts are applied to the gas-side fouling of heat exchanger tubes. Deposition and heat transfer are calculated for superheater tubes in laboratory and utility furnaces. Numerical results for deposit thickness and heat flux are presented. Comparisons with data show agreement, demonstrating that the broad-base engineering approach is promising.
