Fill in the blank (word in bracket) with the appropriate word from the list of words given below. Cogeneration | regeneration | constant | superheating | reheated | lowering | increased Combined cycles | higher | combined cycle The thermal efficiency of the Rankine cycle can be increased by increasing the average temperature at which heat is transferred to the working fluid and/or by decreasing the average temperature at which heat is rejected to the cooling medium. The average temperature during heat rejection can be decreased by the turbine exit pressure. Consequently, the condenser pressure of most vapor power plants is well below the atmospheric pressure. The average temperature during heat addition can be by raising the boiler pressure or by the fluid to high temperatures. Lowering the exhaust pressure or raising the boiler pressure, however, increases the moisture content. To take advantage of the improved efficiencies at higher boiler pressures and lower condenser pressures, steam is usually after expanding partially in the high-pressure turbine. This is done at by extracting the steam after partial expansion in the high-pressure turbine, sending it back to the boiler where it is pressure, and returning it to the low-pressure turbine for complete expansion to the condenser pressure. During a process, liquid water Another way of increasing the thermal efficiency of the Rankine cycle is (feedwater) leaving the pump is heated by steam bled off the turbine at some intermediate pressure in devices called feedwater heaters.
