Developing Steam System Optimization Model

4 Maximal Efficient Operation = Minimal Cost Operation  [Pg.417]

The burning question becomes Is the maximal efficient operation mode also the minimal cost mode The answer is not simply yes or no but with a necessary and sufficient condition to be satisfied. [Pg.417]

The PEE for the condensing path is only 20% as calculated before. Therefore, economically, power import beats the condensing path in this case. [Pg.417]

Until now, we can safely derive the conclusion It is not always tme that maximal efficient operation is the most economical operation. It is tme only when words, the necessary and sufficient condition can be stated as When the PEE is higher than on-site power generation efficiency, the maximal efficient operating mode is also the minimal cost operating mode. Under this condition, the problem of optimizing the steam system is converted to a simplified problem to maximize the cogeneration efficiency. [Pg.417]

Energy supply optimization is about generating steam and power at the lowest cost via optimizing boilers and turbines. At the same time, it is about optimizing power [Pg.417]


Complex steam systems usually feature many important degrees of freedom to be optimized. To establish the steam costs for retrofit of site processes requires an optimization model to be developed. This allows the steam loads for process heating to be gradually decreased and the steam system reoptimized at each setting. The result in cost... [Pg.651]

Although the details of establishing steam balances are discussed in Chapter 16 while steam equipment modeling equations are given in Chapter 15, the intention here is to combine all the related equations to develop a complete simulation and optimization model for the steam system. For specific applications, users can revise the model by providing specific configuration and conditions for the steam system. [Pg.418]
