Abstract As the exhaust rate of the conventional sources has geared up already, this is compelling the power industries to install the power plants based on the non-conventional sources so that future demand of the energy supply can be fulfilled. Among the various sources of renewable energy like wind, hydro, tidal etc., solar energy is the most easily accessible and available renewable energy source. Ensuring the feasibility of any energy source not only technical but also the economical perspective is the most important criteria. This paper has incorporated both the perspective and has done the techno-economic analysis to determine the optimum combination of the PV array size and battery size to minimize the overall electricity generation per unit. In this paper, a standalone solar PV system has been analyzed for the location of Jamshedpur, where an effort has been done to choose the optimum combination of the solar array and battery size within the desired range of LLP so that the electricity generation cost per unit can be minimized. The overall duration of the analysis has been done for a year and the outcome of the research has been verified with the help of MATLAB software.

Conveyor Roller

Belt conveyor is widely used in mine, coal, chemical industry, ports, and power plants. It’s one of the significant devices of continuous conveyor. Roller is a crucial component with regard to belt conveyor system, which supports belts and cargos. In the design of the belt conveyor, a third of major consumption went into rollers. The critical consideration for minimum cost, which including operating, manufacturing, maintenance expenditure, is the selection of idler spacing. For optimization purposes, the optimum pitch between the rollers is regard as more decisive variable, especially for minimizing consumption and reducing rollers’ number than other various factors. This paper discusses the idler spacing to proceed from original technical first, secondly analyzes the effective factors in detail and then deduces rational arrangement mathematical expressions of idler spacing. Simultaneously, combining with the corresponding parameter, we draw up the hierarchical layout figure of idler spacing distribution through the calculation expression. It’s the optimal option of idler spacing that providing an outstanding reference in the actual production.

Background/Objectives: This paper focused on the simplified design of passive mount modulein electric power plants using only spring and damper elements.Methods/Statistical analysis: The selection of elements in a proposed simplified passive mount module was proceeded under the requirement, which is to show the response level same or less as compare to the case of current mount module. The response at the upper location of mount affect to negative effect on the responsible electric power plants so the design criterion should be satisfied with the newly proposed simple mount module.Findings: The frequency response function between the force and response acceleration at upper position of mount module was calculated from the theoretical mount module and the transmissibility function, between two response accelerations at two different passive mount modules, was evaluated for interesting harmonic frequencies (from 1X to 4X). The primary interesting frequency(X)was determined at 30(Hz) since the operation condition of the combustion engine in electric power plant is scheduled to be operated at constant 1,800(rev/min). Several simulation cases can be obtained for different combination of selected dampingcoefficients at the proposed mount module. The magnitude of transmissibility function should be less than one all interesting frequencies and the reasonable condition of the simple mount module can be derived from the simulation result.Then, the validation of the designed simplified mount module was conducted by preparing two kinds of mount module and the acceleration responses were measured at 1,800(rev/min) operation under 100% electric load. The spectral response at interesting frequencies confirms the superiority of the newly proposed mount module.Improvements/Applications: The simplified structure of mount module can be possible to save installation cost and time simultaneously and it is easy to conduct the maintenance of mount module.

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.

The study was conducted in 2019-2020 to assess the perception of the farmers on cropresidue burning (CRB) in Haryana. A total of 180 farmers from three purposively selecteddistricts, namely Karnal, Kurukshetra, and Fatehabad from Haryana, were chosen to collectdata. Stratified random sampling was employed in the selection of blocks, villages, andrespondents. For measuring farmers’ perception, a scale was constructed using Likert’smethod of summated ratings. Farmers perceived CRB as an economical and viable optionand considered it an efficient practice. Most farmers did not perceive the happy seeder asfeasible since it needed a high horsepower tractor. Farmers’ perception was positively andsignificantly correlated with education, operational land holding, and annual income (P<0.05).Hence, there is a need to promote community-based approaches like custom hiring centre,bio-mass-based power plants, mushroom cultivation, etc., through extension and advisoryservices. It may lead to adopting alternative crop residue management options and mitigatingresidue burning in the long run.
