The Essentials of Continuous Evaporation | AIC
Thus, the steam economy will always be less than one. Depending on the initial feed temperature and system losses, the steam economy of a single-effect evaporator typically is 0.75–0.95 kg water/kg steam (4). Improving steam economy. Consider the example of the single-effect evaporator . For heat transfer to occur, the temperature of the ...Get a Quote
Design methodology of heat recovery steam generator in .
The results show that the maximum heat transfer occurs in the evaporator section for high-pressure levels, and in the economizer section for low-pressure levels. The optimum design pressure for the high-pressure level of the steam generator was found to be 100 bar, while that for the low-pressure level was found to be 10 bar.Get a Quote
