Recovery boiler economizer
Webbför 2 dagar sedan · In a conventional steam generator such as a package boiler, the exit gas temperature is independent of steam pressure. With say a 230 F feed water … WebbThe advantages of economizers are as follows. It increases the efficiency of the boiler. It reduces fuel consumption. It reduces heat losses due to flue gas emissions. The temperature of flue gasses ranges between 370°C and 540°C, which reduces thermal stresses in the boiler due to a smaller temperature differential.

Webb1 juli 2002 · Large utility steam boilers are equipped with economizers that use a water-to-air heat exchanger to preheat feedwater using recovered stack heat from hot boiler flue gases. This same basic idea can be used in smaller hydronic heating boilers where there is a nearby demand for hot water. WebbReducing stress magnitude will most often be achieved by raising the temperature of the boiler shell (i.e., raising the bulk water temperature of the boiler) and attempting to isolate the boiler as much as possible from system temperature changes. This can …
