DO THE ANALYSIS

摘要

There are numerous problems here: 1) unknown condensate pressure; 2) possible boiler-water corrosion issues; 3) an indication of capacity overload; 4) possible two-phase flow in the 6-in. vent header; 5) steam at multiple pressures added to a steam header; and 6) un-insulated pipe where condensation can occur. The best solution to this problem is to continue walking down the pipe; get very familiar with the isometrics. Typically, these drawings are a mess. Create accurate drawings. Collect pressure and temperature data. Use an infrared gun to verify which traps aren't working. Identify the sources of the steam, which should give you the pressures. Measure the pressure at the suction side of the condensate pump. Re-calculate the capacity of the flash drum and discuss your findings with one of the steam equipment companies.
