The aim of the present paper is to examine the effect of ambient temperature on the performance of a combined cycle power plant. For this work, the combined cycle plant chosen is NTPC (National Thermal Power Corporation) Dadri, India where a gas unit of 817 MW is installed. The effect of ambient temperature on combined cycle efficiency, gas turbine cycle efficiency, exergy destruction in differ...

This paper shows an improvisation for gas turbine power plants. It incorporates a hydraulic compressor to compress air prior to combustion. The aim is to reduce in-house consumption of the power generated in the turbine, thus increasing the overall efficiency of the power plant. The proposed compressor could also be used in different scenarios.

The biomass and lipid productivity of Chlorella sp. MTF-15 cultivated using aeration with flue gases from a coke oven, hot stove or power plant in a steel plant of the China Steel Corporation in Taiwan were investigated. Using the flue gas from the coke oven, hot stove or power plant for cultivation, the microalgal strain obtained a maximum specific growth rate and lipid production of (0.827 d(...

This process through the indirect use of intense heat in the absence of oxygen is able to reduce the material covered in fuel gas and organic matter. which reduces the material in a combustible gas and inorganic matter. The Thermax© pilot plant allows a thermal degradation that completely sanitizes waste destroying its toxic components through molecular dissociation. This technology also stands...

The concern of risk management has continuously increased in international construction projects. International projects have a high level of risk and complexity, which results in greater possibilities of cost overruns and schedule conflicts when compared with local projects. Therefore, the goal of risk management is to improve project performance by systematically identifying and assessing pro...

The economy of desulfurization system is of great significance for operation of desulfurization system and improving the environment quality in power plant. Based on the desulfurization power price policy, this paper analyzes the cost and benefit structure of the wet flue gas desulfurization system in Chinese power plant; that puts forward the calculation methods of total cost present value, to...

In the ongoing global efforts to reduce Green House Gas (GHG) emissions, a strong emphasis is placed on improving power plant efficiency. Fossil fuel-fired power plants today supply over 65% of electricity in the world, with coal-fired power plants accounting for about 40% of the total. The efficiency of power generation (amount of fuel to deliver a unit of electricity) varies significantly acr...

In this paper, a recurrent fuzzy-neural network (RFNN) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. Since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...

The chlorine containing deposits in the power plant environment is very harmful in terms of degrading the plant component materials. The cyclic reaction starts by the chlorine gas shorten the life of the plant components. In this study, this cyclic reaction is study in detail, which is required further to find the preventive methods for slow down the degradation of the plant components, especia...

This paper deals with the valuation of energy assets related to natural gas. In particular, we evaluate a baseload Natural Gas Combined Cycle (NGCC) power plant and an ancillary instalation, namely a Lique…ed Natural Gas (LNG) facility, in a realistic setting; speci…cally, these investments enjoy a long useful life but require some non-negligible time to build. Then we focus on the valuation of...
