Oct 12, 2020 · The coefficients for the intermediate-pressure evaporator are noticeably lower than the ones for the high and low-pressure evaporators. From the results presented in Fig. 15 and Tables 4 and 5, it is clear that the low-pressure evaporator has the most significant impact on the boiler efficiency, when fouling is present.
Read MoreThe remaining steam continues to expand to 6 kPa. Steam is then condensed at constant pressure and pumped to the boiler pressure of 8 MPa. Steam leaves the process heater as a saturated liquid at 500 kPa.
