and 107d used to form low pressure feed water heaters 107 in fig1 and 2 and the interconnections of the steam lines between these heaters a number of sensors are positioned throughout the plant at various locations to provide immediate and continuous sources of information to warn the power plant operator of potential problems and to generally monitor the operation of the power plant for efficiency purposes for instance referring to fig1 and 2 temperature detectors 60 are preferably positioned at various locations throughout a power plant specifically as shown in fig3 temperature detectors 60 are preferably positioned before and after low pressure feed water heaters 107 and before and after high pressure feed water heaters 105 as well as between high pressure feed water heaters 105a and 105b and between low pressure feed water heaters 107a 107b 107c and 107d likewise as shown in fig1 and 3 temperature detectors 60 may actually be positioned inside low pressure turbine 124 intermediate pressure turbine 122 and high pressure turbine 120 also as shown in fig2 and 3 temperature detectors may also be positioned in the passageways transferring steam extracted from the turbine to specific equipment such as steam lines 123a and 121b similarly level detectors 50 that detect the level of condensation are preferably placed in low pressure feed water heaters 107 and high pressure feed water heaters 105 to detect the level of condensation inside low pressure feed water heaters 107 and high pressure feed water heaters 105 note level detectors 50 are actually labeled 50a 50b 50c 50d 50e and 50f in fig3 and temperature detectors 60 are actually labeled 60a 60b 60c 60d 60e 60f.
