Outlet temperature of steam generator

5. A steam generator unit generates 80 to/hr of steam

A steam generator unit generates 80 to/hr of steam at 50 bars and 400 °C from feed water at 103 °C. the unit consist of boiler, superheater, and economizer and has an efficiency of 82%. The air to fuel ratio is 19:1 while the flue gases temperature at exit from economizer section is 360 C. in order to increase the efficiency to 86% an air

The Boiler Circulatory System: Beyond the Steam-Generating

They are so named because they spray water or wet steam as a means of temperature control. The 811ºF temperature steam circulates through the secondary super-heater tube sections, going up and down until it reaches the secondary super-heater outlet header. The temperature of the dry super-heated steam is now 1,005ºF.

With this particular example, a curve is shown in FIG. 5 (referring to function f(x) in function generator 111) indicating that when the average inlet temperature t INL at the inlet to the heat recovery steam generator goes as high as 1345° F., the admissible outlet temperature for the superheated steam will be as low as 952° F., whereas when such inlet temperature is down to 1205° F., and there is a need for more heat from one boiler, the outlet temperature …

7.6. Rankine cycle | EME 812: Utility Solar Power and

Increasing the boiler pressure results in higher average steam temperature in the boiler. This effect allows additional work to be done in phase 2-3 (Fig. 10.3c). However, there is some loss of useful work in phase 3-4 because of necessity to re-heat the steam. Reheating is used to mitigate higher moisture content of the high-pressure steam.
