Recuperated water injection plant

Similar calculations (Fig. 6.10) were made for intercooled cycles, without and with water injection, i.e. comparing the efficiency of the dry CICBTX cycle with an elementary recuperated water injection plant, now a simple version of the. so-called RWl plant (see Section 6.4.2.1). Again there is an increase in thermal efficiency with water injection, but it is not as great as for the simple EGT plant compared with the dry CBTX plant the optimum pressure ratio, about 8 for the dry intercooled plant, appears to change little with water injection.

There have been a larger number of proposals for recuperated cycles with water injection and evaporation, but all these can be interpreted as modifications of the EGT plant, which is essentially a wet CBTX cycle, as explained above.
