Hitting the Layup: Case study on HRSG corrosion protection

Dec 21, 2020 · Thus, oxygen-laden water may enter the steam generator during normal operation and, even more critically, during boiler fillings. In the latter case, the influx of cold, oxygen-saturated water can

Lay-up of Heating Boilers

1 — Draining the boiler. Perform a bottom blow-off on the boiler before and then after shutdown to remove sediment and scale and to drop the unit's pressure and temperature. Once the unit is at zero psi gage pressure and water temperature is under 140°F, open an air vent and boiler drain to empty the boiler.

Analysis of Flue Gases with GC and TCD Detection

and Molecular Sieve 5A with valve oven and TCD. A typical schematic diagram of the valve oven is given in Figure1. The GC analytical conditions are listed in Table 1. Introduction Flue gas is the gas that exits via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler, or steam generator to the

A second danger is a blow-out of components due to pressure build-up. Source of the pressure is the steam produced by constant heating of the reboiler, or that injected from a separate steam generator. Pressure builds up if too much resistance occurs from the flow of gas up the column or the flow of product out of the condenser.
