There exists a widespread interest in the application of gas turbine Power Augmentation Technologies (PATs) in both electric power generation and mechanical drive markets. This interest is attributable to liberalization in the power generation sector, increased electric rates during peak demand period and need for a proper selection of the gas turbine in a given application. In the Part II of this study, an analytical evaluation of the ambient temperature effect on gas turbines performance is presented. Further, the achievable power boost due to the installation of the most adopted PAT strategies is deeply investigated. Considering a whole year of operation for a large number of worldwide locations, also the behavior change — due to the use of the PATs — on both the energy production and the economic aspect will be analyzed and discussed.

The problem of sludge dehydration assumes an ever growing importance, owing also to the constant increasing diffusion of water treatment plants. To better understand the entity of the problem it is enough to pay attention to the fact that water treatment plants can produce up to hundreds of tons per day of sludges, whose disposal is of not less importance if compared to the treatment of liquid effluents.

The present work describes a method of small-scale generation of electric power using a horizontal axis Magnus Wind Turbine (MWT). Present levels of environmental pollution from fossil fuels and the high cost of generating electricity can be solved by using Green energy extracting wind turbines. Many researchers are trying to use renewable sources of energy to solve this problem. The present work investigates the generation of electricity by using Horizontal axis Magnus wind turbine. It is observed with a small investment and proper selection of the location of the site for deployment, the wind power is a better economical solution than other methods

Abstract A thermodynamic and economic analysis of a GT10 gas turbine integrated with the air bottoming cycle is presented. The results are compared to commercially available combined cycle power plants based on the same gas turbine. The systems under analysis have a better chance of competing with steam bottoming cycle configurations in a small range of the power output capacity. The aim of the calculations is to determine the final cost of electricity generated by the gas turbine air bottoming cycle based on a 25 MW GT10 gas turbine with the exhaust gas mass flow rate of about 80 kg/s. The article shows the results of thermodynamic optimization of the selection of the technological structure of gas turbine air bottoming cycle and of a comparative economic analysis. Quantities are determined that have a decisive impact on the considered units profitability and competitiveness compared to the popular technology based on the steam bottoming cycle. The ultimate quantity that can be compared in the calculations is the cost of 1 MWh of electricity. It should be noted that the systems analyzed herein are power plants where electricity is the only generated product. The performed calculations do not take account of any other (potential) revenues from the sale of energy origin certificates.

There is a widespread interest in the application of gas turbine power augmentation technologies such as evaporative cooling or mechanical chilling in the mechanical drive and power generation markets. Very often, the selection of the design point is based on the use of ASHRAE data or a design point that is in the basis of design for the project. This approach can be detrimental and can result in a non optimal solution. In order to evaluate the benefits of power augmentation, users can use locally collected weather data, or recorded hourly bin data set from databases such as TMY, EWD, and IWS. This paper will cover a suggested approach for the analysis of climatic data for power augmentation applications and show how the selection of the design point can impact performance and economics of the installation. The final selection of the design point depends on the specific application, the revenues generated and installation costs. To the authors’ knowledge, this is the first attempt to treat this topic in a structured analytical manner by comparing available database information with actual climatic conditions.

Hybrid PSOFC/GT cycles consisting of pressurized solid oxide fuel cells integrated into gas turbine cycles are emerging as a major new power generation concept. These hybrid cycles can potentially offer thermal efficiencies exceeding 70% along with significant reductions in greenhouse gas and NOX emissions. This paper considers the PSOFC/GT cycle in terms of electrical and mechanical power generation with particular focus on gas pipeline companies interested in diversifying their assets into distributed electric generation or lowering pollutant emissions while more efficiently transporting natural gas. By replacing the conventional GT combustion chamber with an internally reformed PSOFC, electrical power is generated as a by-product while hot gases exiting the fuel cell are diverted into the gas turbine for mechanical power. A simple one-dimensional thermodynamic model of a generic PSOFC/GT cycle has shown that overall thermal efficiencies of 65% are attainable, whilst almost tripling the specific work (i.e. energy per unit mass of air). The main finding of this paper is that the amount of electric power generated ranges from 60–80% of the total power available depending on factors such as the system pressure ratio and degree of supplementary firing before the gas turbine. Ultimately, the best cycle should be based on the “balance of plant”, which considers factors such as life cycle cost analysis, business and market focus, and environmental emission issues.
