The pyrolysis of non-cured Japanese burley tobacco leaves was carried by varying tobacco particle sizes, temperature, and nitrogen gas flow rates. Linear regression and statistical analysis using ANOVA were conducted to investigate the significance of the parameters in bio-oil yield and nicotine concentration in bio-oil. The flow rate of nitrogen gas showed a direct correlation with a decrease in liquid yield and an increase in gas yield. On the other hand, the temperature and size of particles showed only a slight impact on the liquid yield. These two parameters also strongly affected bio-oil chemical composition, particularly the nicotine concentration, which has promise for medicinal applications. These results show that the particle size can change the selectivity of tobacco bio-oil chemical compounds and should be carefully examined as a key process parameter.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"454 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116071060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially the samples were dried at 105°C to remove moisture content up to 15% and then pellets were prepared using biomass and cow dung in 1:1. The samples were characterized using FT-IR, compressive strength and TGA analysis during which their compositional, mechanical, thermal and physicochemical properties were analyzed. The energy density of biomass pellets was also calculated. Bamboo leaf being the promising candidate exhibited improved properties compared to other biomass pellets with maximum compressive strength of 11.6MPa and energy density of 19434.8 MJ/m3 along with enhanced structural properties. Whereas wood mix indicated the least compressive strength i.e. 3.73MPa but highest energy density i.e. 20456.5 MJ/m3 and good thermal characteristics. The lignin content present in cow dung is one of the main sources that makes it good biofuel. The experimental results revealed that cow dung is a most suitable binder as it is abundantly available and also increases the durability of biomass pellets comparative to other binders used in different studies.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127324648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetrons are expensive and sensitive to variations in terminal voltage. Generally a soft start procedure is adopted to save the magnetrons that requires a specific pulse shape and transient behaviour of the power supply. This paper implements PI control for a previously designed power supply to make it reliable for a 10 kW magnetron. The requirements and issues are discussed in detail with respect to unregulated resonant DC power supply and it is argued that PI control is an attractive choice for its simplicity. Simulations are performed in PSIM and MATLAB-SIMULINK using real values of the circuit components and the controller is applied to the circuit instead of a mathematical model. Hence the work presented in this paper provides a strong foundation for the realization of the practical system. The controller is evaluated rigorously for line and load regulation and other transient characteristics. The proposed PI control is found very promising for the intended application and the resonant DC power supply design presented previously.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132532689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the harmonic analysis will be presented in Industry using Fluke Energy Analyzer. The measured THD values for the Voltage and current will be used to model and analyze overall harmonics in the complete three-phase distribution system of Textile Plant through simulation using ETAP software.

The proposed CQD solar cell is of the architecture of glass substrate: fluorine tin oxide (FTO)/ZnO/titanium dioxide (TiO2)/PbS- tetra-butyl ammonium iodide (PbS-TBAI)/PbS-1, 2-ethanedithiol (PbS-EDT)/gold (Au) – contacts with power conversion efficiency (PCE) of 15.28% and is modeled and investigated in solar cell capacitance simulator (SCAPS). Here FTO is the oxide layer (OL), TiO2 is used as an electron transport layer (ETL), PbS colloidal quantum dots (CQDs) layer treated with PbS-TBAI serve the purpose of generating electron-hole pairs whenever a solar cell is exposed to solar insolation and PbS CQDs layer treated with EDT is used to extract the holes. The impact of varying layer thicknesses on PCE, open-circuit voltage (Voc), short circuit current density (Jsc) and fill factor (FF) is also discussed in the paper. The quantum efficiency (QE) of the proposed solar cell reveals that the proposed PbS- CQD solar can capture a wider range of incident light wavelengths across the broader range of solar spectrum depicting that this research effort can become a useful guide in the future fabrication of high efficient PbS CQD solar cells.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127514063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a rapidly growing load demand at 10% per year, Punjab is currently facing a substantial demand-supply gap of 5,000MWs. With two-third of the entire consumption of total generated power in Pakistan, Punjab is worst affected by the shortfall, economic and social consequences resulting from electrical load shedding. Inefficient energy industrial processes, building designs and electricity usage by consumers drives up overall and peak demand and impose great stress on the available energy supply. Acknowledging the issue, the provincial government of Punjab established the Punjab Energy Conservation and Energy Efficiency Agency (PEECA) in 2015, to promote, develop and implement energy efficiency (EE) projects and policies at the provincial level. To continue widening the scope and increase the scale of Energy Efficiency projects in Punjab, other than direct funding from the Government, monetary investment from other entities such as state enterprise and private investors is instrumental. However, various challenges exist in attracting private investors to invest in EE related projects. In order to have a complete understanding of the challenges involved, questionnaires were issued to various stakeholders such as Multi-Laterals, Power Distribution Companies (DISCOs) and Energy Service Companies (ESCOs) in consultation with the client (PEECA). From the responses, regulatory issues, bureaucratic delays and lack of awareness of EE among the investors and community were some of the factors highlighted. Considering the issue from a holistic perspective, the team reviewed various investment models in the energy efficiency sector from the developing and developed world and proposed two refined investment models, taking into account the factors highlighted in the questionnaire and addressing the political, social and environmental issues involved. The team believes that the policy proposal will help PEECA manage the demand side of electricity more effectively and help reduce the consumption of fossil fuels, and GHG emissions. This will encourage the people of Punjab to live within the finite resources of earth and act as a form of stewardship towards future generations. It will further improve the lives of millions since climate change is the cause of frequent floods in Pakistan and damages are caused due to this calamity.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121132592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To be able to do this, it is necessary to take an initial step by conducting an energy audit, which is a method for calculating the level of energy consumption of a building/building. In this study, the authors will analyze the energy consumption and potential energy efficiency at the Diponegoro University Campus. Energy efficiency analysis will be based on electrical energy consumption data from 2016-2020, calculating the Energy Consumption Intensity (IKE) and Electric Power Quality. The consumption of electrical energy at the Undip Campus reaches 20,253,418 kWh or Rp. 16,415,550,042 in 2019.

Temperature and irradiance levels have a high impact on the power generation of photovoltaic modules, but due to non-uniform irradiance levels, PV modules generate non-linear P-V curves. Maximum power point tracking control is introduced to harvest maximum power from PV modules. In this paper, a general regression neural network trained with sailfish optimizer (GRNN-SFO), a hybrid MPPT technique is presented. Highly effective global optimization of sailfish optimizer combined with precise estimation capability of the general regression neural network makes GRNN-SFO highly effective for MPPT control. Comparison is made with GRNN-PSO and GRNN-P&O to check the performance of the proposed technique. Two cases are presented in order to validate the superior performance of GRNN-SFO. The comparison shows that GRNN-SFO tracks the global maxima with greater than 99.9% efficiency and 12 ms faster tracking time under fast varying irradiance and partial shading condition. The analysis of statistical data has also been exhibited in order to examine the robustness and responsiveness of the proposed technique.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125812151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
