| Abstract: | Based on the conventional heat balancing method, by making use of the basic theory of equivalent heat drop and in terms of an expression of specific work done by fresh steam and flow coefficient of steam and water, a mathematical model is derived for thermal cycles of fossil fired power plants, both generally applicable for calculating the thermal efficiency as for distribution calculation of steam and water. A practical example shows that results obtained with this generally applicable mathematical modal for heat cycles of fossil fired power plants are the same as those obtained with the conventional method of heat balancing. |
