Optimizing steam system cogeneration efficiency

No matter how much the steam system could be optimized, one relevant and important question is What is the maximal efficiency that the steam system can achieve The answer will be provided by the concept of cogeneration efficiency that is discussed next. 

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.
