Part 1 - Determine the fuel cost. Each kilogram of condensate not returned to the boiler feedtank must be replaced by 1 kg of cold make-up water (10°C) that must be heated to the condensate temperature of 90°C. (ΔT = 80°C). Calculate the heat required to increase the temperature of 1 kg of cold make-up water by 80°C, by using Equation 2.1.4.Get Price

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.Get Price
