This paper aims to design, analyze, and find the optimized performance of a novel municipal solid waste fired combined cycle power plant, to cater the utility electrical needs of an urban municipality. Performance of the plant is evaluated through energy, exergy, economy and environmental analyses. Response surface methodology is used as optimization tool for finding the optimal performance of the plant. Air compressor outlet pressure, air turbine inlet temperature, hot end temperature difference of the dual combustor and heat recovery unit, organic vapor turbine inlet temperature, and organic vapor turbine inlet pressure are considered as input parameters for finding out the optimal values of the response parameters such as exergy efficiency and levelized unit cost of electricity. This particular regression model offers extremely accurate results for the response parameters. The optimal values of exergy efficiency and cost of electricity are found to be about 39% and 0.085 $/kWh (5.3 INR/kWh), respectively at the air compressor outlet pressure of 4 bar, air turbine inlet temperature of 1100 °C, hot end temperature difference of 70 °C, and organic vapor turbine inlet temperature and pressure of 201.8 °C and 5 bar, respectively. At this optimal operating point, the plant can deliver 1810 kW electricity with an environmental damage cost savings of 270 $/year compared to the environmental damage cost associated with the conventional land-filling of municipal solid waste. Composite desirability for this model is found to be 1, indicating the fact that the model predicts the best suitable results for the proposed plant’s performance optimization.

Machining of titanium-based hybrid composites by conventional method is very complicated due to its enhanced strength-to-weight ratio, corrosion resistance, abrasion resistance and fatigue resistance which is extensively used in aerospace, spacecrafts, marine, automobile, sports and biomedical applications. This paper provides an optimization technique of wired electro-discharge machining (WEDM) of titanium-based hybrid composites varying peak current and pulse duration as main input process parameters for machining complicated complex silhouette which is practically unfeasible to develop by conventional machining. In this paper, investigation is done on response surface methodology (2 factors 4 levels) design of experiments (DOE) on output response like surface roughness, and satisfactory results are obtained and authenticated by the confirmatory test. Both the process parameters displayed enormous impact on the output response, and an optimal condition and solution is obtained to achieve the best output response.

This study reveals thermodynamic, economic and environmental evaluation of full site-repowering proposal of coal-fuelled thermal power station through integrated gasification combined cycle (IGCC) technology with downstream MCFC integration for CO2 capture. High-ash Indian coal is mixed with petroleum coke and then gasified in conventional Shell gasifier. The syngas is used to run the integrated gasification combined cycle. Then at the downstream of the combined cycle, natural gas-fired MCFC unit is integrated for CO2 capture. The findings suggest that the repowering results in 6% capacity increase, 9.2% point efficiency enhancement with a 90% capture of emitted CO2 from the plant. The cost of electricity becomes high as 108 $/MWh. Once the cost of MCFC price would go down, it would go down further.

The present study reports the model development and thermodynamic analyses of an integrated municipal solid waste (MSW) fuelled externally fired air turbine (AT) plant and hot water generation plant for Indian cities. Waste generated from a typical Indian municipal town (Kandi) is considered to be the fuel input to the plant. Dry and segregated MSW is burnt in the combustion chamber of dual combustor-air heating (DCAH) unit which then heat-up the working fluid (air) of the topping AT cycle. Exhaust heat from the DCAH unit is utilized to produce hot water to meet the demand of town. Effect of topping compressor’s pressure ratio (rp = 4–16), air turbine inlet temperature (ATIT = 900, 1000 and 1100 °C) and hot end temperature difference (HETD = 70–150 °C) on the energetic, exergetic and environmental (3-E) performance of the plant is analyzed and reported here. It is observed that the plant can deliver 1100 kWe of electricity and about 2450 L of hot water (hourly basis) at the base case scenario. Maximum exergy is destroyed at the DCAH unit and at the WHU, respectively. Sustainability index (environmental parameter) value is found to be 1.56 at the base case. Furthermore, it is observed that these plant operational parameters can be influential for evaluation of 3-E performance of the plant.

A comparative analysis of cascade refrigeration system is presented in this paper. Different pairs of refrigerants are used in this simulation. Both energy and exergy analyses have been conducted. Since a cascade system uses two different refrigerants, R744 is used in the low-temperature unit and R134a, R717, R1234yf, R290, R1234ze, R600 are used alternatively in the high-temperature unit for the purpose of comparative study. Values of COP and the second law efficiency are evaluated and compared with each different pairs of refrigerants used. This paper shows whether the use of refrigerants with low ODP and GWP values is viable or not. The sole purpose of this paper serves in identifying an appropriate refrigerant pair with lower environmental risk which can be really efficient in operating a cascade system. It was observed that R744-R717 attained the highest COP value equivalent to 7.848, and the highest ECOP value of 0.9838 was also attained by R744-R717. R744-R600 also obtained COP value of 7.741 and ECOP value of 0.9833 which is quite good.

Efficient energy utilization from renewable energy sources can resolve multidimensional problems of environmental pollution, energy security and reduction in conventional fossil fuel reserves. In this circumstance, biomass-based energy systems can play an important role. In this study, modeling and analysis of an advanced integrated co-generation system comprising of a biomass gasifier, a solid oxide fuel cell module and a heat recovery steam generator have been carried out for generating power and process heat. The proposed system has been evaluated through exergetic and economic methods. Furthermore, response surface methodology has been applied for the multi-objective optimization of the system. Current density, pressure ratio of the secondary air compressor and saturation pressure of steam at the heat recovery steam generator are considered as the inputs for predicting the optimum performance parameters i.e., exergy efficiency, levelized cost of energy and levelized cost of exergy. Regression models, generated from the analysis of variance tool, are found to have a very high degree of accuracy for the exergy efficiency, levelized cost of energy and levelized cost of exergy. The optimal levels of the current density, pressure ratio and saturation pressure of steam are found to be 5101.01 A/m2, 4 and 12 bar, respectively. At this optimum condition, exergy efficiency, levelized cost of energy and levelized cost of exergy of the cogeneration system are 46.58%, 0.0454 $/kWh and 0.0657$/kWh, respectively. Composite desirability is found to be on the higher side (around 0.90), which indicate that the setting seems to attain favorable results for all the responses as a whole.

This article proposes an innovative distributed hybrid power system where the biomass gasification technology is integrated with the molten carbonate fuel cell, an externally fired gas turbine, and a supercritical carbon dioxide cycle. The thermodynamic, economic and environmental performances of the proposed system are extensively studied to show the impact of the main operational and design parameters. The proposed small capacity hybrid power system yields the highest energy efficiency of 40.88%, which is close to the efficiency level of the large-scale biomass gasification based combined cycle system. The maximum exergetic efficiency of the proposed power system is estimated to be around 34.07%. The biomass gasifier (31.79%) contributes the highest amount of exergy destruction, followed by the primary heat exchanger (15.97%), combustion chamber (14.01%) and the molten carbonate fuel cell (12.53%) unit. The sensitivity analysis reveals that the cost of electricity can reach up to 0.1057 $/kWh. A comparative performance analysis, among other biomass-fueled power generation systems suggests that the developed power system yields better techno-economic performance than the other previously proposed system configurations. The environmental analysis reveals that the proposed plant can reduce maximum up to 1510 ton of CO2/year, which yields an environmental benefit of 21,901 $/year, in comparison to a fossil fuel-based plant of similar capacity.

During any machining process, there exists an essential criterion to determine the surface characteristics to achieve the desired product quality. Considering this fact as a primary objective, the present study is carried out to determine the average surface roughness (Ra), root mean square (Rq), and average maximum height of the profile (Rz) values of surfaces generated during the machining of MS rod. Plain turning operation is carried out in a lathe considering different machining parameter, viz. cutting speed and depth of cut and using different cutting fluids, viz. mustard oil, kerosene oil, olive oil and water as well as in dry condition (without coolant) via MQL technique. Single-point cutting tool, made of high-speed steel (HSS) has been used in this experimentation work. The study shows that higher spindle sped and depth of cut result in higher surface roughness, irrespective of cutting fluid used. Furthermore, it is experienced that if low viscous cutting fluids (e.g., kerosene and water) are used as cutting fluids, the machined surface becomes rougher.

Factual material selection is essential in the manufacturing arena with a superior product and minimum cost. This paper highlights on the advanced multi-criteria approaches namely additive ratio assessment (ARAS) and multi-attributive border approximation area comparison (MABAC) methods for the best material selection of a hybrid composite using aluminum (Al) as base material varying different reinforcement weights and recycling with various industrial wastes by stir casting. Al/WCE gives superior tribomechanical properties at lower cost than the other reinforcements. ARAS and MABAC methods are applied, based on the properties and attributes of the hybrid composites, to compare between the computational and experimental results. The results exactly corroborate with the previous research results which authenticate the expediency of these methods during the solving of complex hybrid material selection problems. Out of 48 different samples, the best hybrid composite material obtained by ranking is material number A30 by ARAS approach (rank 1) which is Al+Al2O3 at 12.5% wt. addition and material number A24 (rank 2) which is heat treated 12.5%wt. WCE. But the same A30 is obtained to be rank 5 and A24 is obtained to be rank 1 by MABAC method. A24 is obtained to be the best hybrid composite after the experimentation.

The study emphasizes on the modeling and thermodynamic performance prediction of a novel biomass gasification-based combined cycle plant. It consists of a topping indirectly heated topping gas turbine (GT) cycle and a bottoming supercritical CO2 (S–CO2) cycle for combined power generation. Sawdust is considered as the driving fuel of the plant, which is gasified in a downdraft gasifier and thus the derived producer gas is further burnt in a combustor-heat exchanger combined (CHX) unit. The CHX unit indirectly heat-up the working medium (air) of the topping GT cycle and the CHX exhaust is further utilized in the bottoming S–CO2 cycle to produce electricity in a combined manner. Simulated performance of the plant is judged over wide ranges of considered pressure ratio (rp) and the gas turbine inlet temperature (TIT). The rp value is varied between 4–16 and the TIT is varied between 900 and 1100 °C. Overall electrical efficiency of the plant is about 46% at rp = 4 and TIT = 1000 °C. At the same thermodynamic state points, calculated value of required biomass input is 0.017 kg/s and also the combined net output from the plant is about 140 kW. Overall electrical efficiency value increases with increase in rp value, for all GT TITs as well as hot end temperature difference (HETD) of the CHX unit.

This paper presents a techno-economic and environmental assessment of a biomass gasification based power plant integrating a solid oxide fuel cell module, an externally fired gas turbine and an organic Rankine cycle. The proposed biomass based system is nonparallel with the conventional biomass based power generation system because of biomass gasification, solid oxide fuel cell, externally fired gas turbine, organic Rankine cycle have been combined in a single system. The thermodynamic and economic performances of the plant have been investigated under the varying operating and design parameters. The maximum energetic and exergetic efficiencies of the system are computed to be 49.47% and 44.2%, respectively. Exergy analysis predicts that the biomass gasifier unit contributes highest amount of exergy destruction (38.91%) in terms of total exergy destruction of the system, followed by solid oxide fuel cell (21.24%) and secondary heat exchanger (13.11%). Economic analysis forecasts that the minimum levelized unit cost of electricity would be 0.086 $/kWh. A performance comparison with other conventional biomass based power generation systems shows that the proposed system exhibits better efficiency and cost of electricity than others. Environmental analysis predicts that the maximum CO2 emission reduction potential is computed to be 3564 t CO2/year compared to the fossil fuel based power plant.

In this paper, a biomass gasification-based molten carbonate fuel cell (MCFC)-integrated advanced power system has been modelled and analyzed. The proposed system consisted of a biomass gasifier with hot gas cleaning equipment, a MCFC module, an indirectly heated air turbine and an organic Rankine cycle. Energetic, exergetic and economic (3E) analyses of the proposed power generation have been carried out. The effects of variation of operating and design parameters on the overall performances of the system have been showcased. Base case energetic and exergetic efficiency is found to be 38.49% and 32.7%, respectively. Exergetic analysis discloses that the highest exergy destruction takes place at gasifier (34.15%) followed by primary heat exchanger (16.15%), after burner (14.88%) and MCFC (13.80%).

This paper presents economic impact analysis of partial repowering of a 250 MW existing coal fired power plant. In this repowering scheme, out of five operating coal mills, two mills are proposed to be taken out and a pressurized combustion chamber is introduced which burns the coal of the ousted coal mills. The product gas of pressurized combustion is cleaned and expanded in a Gas Turbine and its exhaust is fed to the existing boiler with modified burners. Feed water heating is proposed by using the waste heat of repowered boiler exhaust. The study shows that the unit cost of electricity (COE) of the repowered plant is less what it would have been if the plant was retrofitted with monoethanolamine (MEA) based CO2 capture system for equivalent emission reduction. The cost of CO2 avoided (CCA) for this repowering scheme is also far better than that achievable with MEA retrofit.
