thermal efficiency of the ideal cycle for the gas turbine power plant depends only upon its pressure ratio r and specific heat ratio y- The efficiency of the ideal cycle is independent of the temperature of the cycle. Fig. 4-3 Air cycle efficiency versus pressure ratio for the ideal open cycle gas turbine power plant.
Large combined cycle power plants were originally developed as baseload units (one start in every 1000 hours of operation). The reality has been very different and most combined cycle power plants are operating under cyclic conditions where the load at off prime time could be …
SELECTION CONSIDERATIONS OF COMBINED CYCLES AND COGENERATION PLANTS Gas (combustion) turbine research performed in the 1970s hinted that high pressure ratios and very high temperatures are required to achieve high efficiency. However, modern engine technology proved that the Carnot cycle’s fundamentals are valid. Only high tem per-

Key words: cation conductivity, cycle chemistry, combined cycle, diethylhydroxylamine, neutralizing amine, flow-assisted corrosion (FAC), acid anions, chloride ABSTRACT Cation (or acid) conductivity is the main control parameter in the cycle chemistry of many combined-cycle power plants today.
Degradation of efficiency and power characteristics of combined cycle power plant. The selection of the working parameters of the entire power unit, including efficiency and electric power of the unit, is made at the design stage of the combined cycle power plant.
Extensive layout designs indicate that NET Power's gas cycle will have a footprint of one-third to one-half the size of a traditional combined cycle plant of similar output. This small footprint is also a result of the high pressure nature of the cycle, which leads to smaller components.
Combined Cycle Gas Turbine Combined Cycles Today • Plant Efficiency ~ 58-60 percent – Biggest losses are mechanical input to the compressor and heat in the exhaust • Steam Turbine output – Typically 50% of the gas turbine output – More with duct-firing • Net Plant Output (Using Frame size gas turbines) – up to 750 MW for 3 on 1 ...
new generation of plants achieves impressive results In last month’s issue an analysis of the operational characteristics of various power generation technologies (pp 61-65) concluded that modern combined cycle power plants, with cycling and fast start capabilities, have

Natural Gas fired (including LNG fired) power plants account for almost 20 % of the world’s electricity generation. These power plants use Gas Turbines or Gas Turbine based combined cycles. Gas turbines in the simple cycle mode, only Gas turbines running, have an efficiency of 32 % to 38 %.
in a combined cycle power plant is presented. The results show that the method can increase the total efficiency and reduce the initial cost of the power plant. The method is applicable for both retrofitting existing plants and for new plants. The to effect ofusing low- calorific bio-fuels in a combined-cycle power plant was investigated.
