We here take an interest on how to maximize the work delivered by the steam turbines using the so-called Thermo Vacuum Pump (TVP). This work represents a design innovation paper proposed in a theoretical emphasis.
There is a knowledge gap in utilizing the Condensation in maximizing the overall efficiency of the Thermal Power Plants. The paper basically aims to propose the TVP as a new method to close this gap where the Air Cold Condenser type is used.
Thermo vacuum pump (TVP) is a thermodynamic machine increases and controls the vacuum at the steam turbine outlet by circulating specific amount of condensate, or steam in some cases, and injecting it in engineering manner into the steam stream at the condenser inlet again.
This paper justifies the research results using theoretical equations because the paper is aimed at providing a basic knowledge about the TVP. However, the paper confirms the validity of a new design opportunity, in principle, which needs further work out in the future.
Anyhow, installing TVP will basically (1) enable to increase the loading capacity of the steam turbine at winter and (2) enable to reduce the load reduction at summer.

It is an engineering study introduced to show some of the design considerations that must be perceived to avoid set of the common engineering mistakes. These mistakes are clarified practically depending on the case study adopted in fuel oil unloading system at one of the main power plants in country of Jordan. Fuel oil unloading system at Amman power station works with an overall efficiency of about 13.8%. This low efficiency comes from several design mistakes, which are mistakes in the pumps number selected and arrangement selection, pumps characteristics selection and pumps suction head selection. This work introduces two alternatives to solve these problems in shade of the design considerations deduced from the existing design mistakes and " Repowering " concept. The first alternative is to replace the pumps used in this system with screw type pumps; this solution increases the efficiency to about 75% and makes savings of about 11,283annuallyforpaybackperiodof20years.Thesecondsolutionistooperatetheexistingpumpinadifferentmannerwithmakingslightchangesinthesystem;thissolutionincreasestheefficiencytoabout37.9611,283 annually for pay back period of 20 years.

Al-Husain thermal power plant, which used to be one of the main power plants in Jordan, is redesigned in this project and proposed as a combined cycle power plant. This work introduces a wide and various practical information about power plants, so it can help the studiers and the students to coin a comprehensive, wise and true concepts about power plants design and performance.
