Making the Tube System's Fitting Parts of the Low-Pressure Evaporators Used in the Heat-Recovery Boilers of Combined-Cycle Units More Resistant to Erosion-Corrosion Wear During Operation

摘要

We present the results of calculation-analytical investigations into the effect of various parameters and factors on the rate of wear in the tube system elements of low-pressure evaporators used in the heat-recovery boilers of combined-cycle plants. Factors causing damage to these elements are established, and the dominating mechanism through which this damage occurs (erosion-corrosion) is determined. Measures for making the tube systems of combined-cycle plants more resistant to erosion-corrosion wear are proposed.
