Energy auditing of payment tiles making small scale industry: Suggestions and recommendations for energy conservation

Even 3Ms Management Principle shifted to 4Ms including managing of energy which is critical factor in operation of any industry. In Energy Management, Electrical form of energy has given more priority because of direct impact on price fixing. Even modern energy conserving devices are comes into market, Small Scale Industries due to lack of awareness, proper selection and utilization is not arrived. This paper discussed about complete energy auditing in small scale tiles making industry by Gandhigram Rural Energy Centre Students using energy auditing Instruments like Power Analyzer and given suggestions for improving the Power Quality.

Energy conservation potential in rural industry: A case study on coir industry

Energy Conservation takes a critical point in deciding the profit cost of any product. However the concept of energy auditing or energy conservation potential study in Rural Industry not fetched because of lack of awareness. This study aims in studying the unorganized Rural Industry - Coir Industry about their power consumption and saving potential. Online Power analyzer, Thermal Imager has been used. Form the analysis it was found that unbalanced loading was there. By proper sequencing the balancing of loading has been achieved it not only reduces the power but also reducing the power factor penalty.

Performance and economic study of on-grid and off-grid solar photovoltaic system

Solar PV power production is one of the developing system in India under JNNSM. This paper proposed the performance and economic analysis of on - grid and off - grid system. This paper discussed about the power usage of building, panel required, Inverter rating, charge controller and battery analysis for both on-grid and off-grid system. This paper also analyzed the economic analysis and net profit at 6th, 11th and 16th year of on - grid and off - grid system and also comparative study carried out in both system.

Increasing solar PV output by controlling environmental parameters

Even though India started commercial solar PV power plants, the efficiency of the PV system has not been raided. Many investigations have been made material design and characterization. But the major influencing parameters for the solar PV output is environmental parameters like dust, temperature, air velocity etc. In this project an attempt has been made to increase ambient humidity near the panel to near saturation humidity which leads 12-16 % increase power output. In a huge power plants this device can be put in to use to increase the net power output and reduce the cost.

Decentralised Waste Management System for Sustainable Habitat Development

Municipal Solid Waste plays a vital role in creating pollution to the environment. The present scenario shows that household waste contributes nearly 35% from the total MSW generation in India, in which more than 25% of waste is biodegradable. By considering 127,285 metric tonnes per day MSW generation in India, this paper concentrates on the household solid waste management in a cluster level which reduces the overall collection and transportable energy and cost. The wastewater generated in the cluster particularly spent was water from the kitchen, and washing has been effectively worked for Colocasia and Cana Indica. The main advantage of Colocasia is that it can be used for medicinal purposes such as strengthening bones and teeth. For the biodegradable solid waste, effective micro-organisms’ method has been adopted to convert the waste into fertiliser at fast rate.

A critical analysis of Power Quality issues in Data Center

Data Center in electrical power system is used to record and store all the activities in the power system network. Data center have the Information Technological (IT) equipment Power Supply Unit (PSU) to process the power system data. Uninterrupted power supply (UPS) unit required for powering IT equipment PSU. IT equipment PSU and UPS absorbs more reactive current and inject harmonic current into the power system network. This paper analyses the Power Quality issues of IT equipment PSU and UPS used in the Data Center. This paper also give a suggestion for mitigation of harmonics present in the data Center.

Implementation of energy conservation and management activities and its economics in GRI boy's hostel - a case study

Although energy conservation and management has played a major role for improving the energy efficiency in developing countries. In India, industries are mainly focused on the energy conservation and management. Educational institutions/ private/ government hostels and hotels have not fully implemented the energy conservation and management (ECM) measures. This paper focuses on the energy conservation and management approach, without affecting the quality and quantity of electrical and thermal load in boys hostel at The Gandhigram Rural Institute (GRI) - Deemed University. The GRI mess is separately provided with Electrical Service Connection from Tamilnadu Electricity Board (TNEB) and thermal energy needed for the cooking has been supplied by Wood feeding Boiler and LPG. Additionally, DG set has been provided in order to support at the time of power failure. The electrical load and thermal load of boiler cooking of mess can be optimally compensated through Cogeneration combined cycle method. By incorporating this method, Wood consumption for boiler will be avoided. In addition to this power consumption from TNEB is reduced. Economic study on replacing LPG gas cooking by Biogas is also done. This paper discuss about the economic savings after the implementation of Cogeneration. Additionally, the economic approach is extended for the additionally ECM approach in GRI mess (replacement of fluorescent tube lamps with LED tube lamps). This paper also discusses the economic effect of cogeneration by additionally ECM approach and overall economics and performance after and before implementing ECM activities.

Value addition of agro products using renewable energy sources: Bottlenecks and solutions

the design of solar drier is still an art rather than Science. Science of drying of product should be understood well before developing the solar drying technology. Once the technology is well established, then solar drying engineering should be attempted so that the technology is cost effective and user-friendly. Unfortunately these aspects are not followed. With the result, many solar dryers are in the market with very poor performance and exorbitant cost. The present day solar dryers have driven away the users from “going for it”. A best performing solar dryer within the reach of common mans budget would definitely increase the confidence among public and would result in quality and products in quantity. As a case study we have taken solar dryer with biomass combustor to analyze dryers performance which was exclusively used for coconut drying.

Performance analysis of LED and florescent lamps a case study of street lightning system

Now there is tremendous appeal of ensuring energy security by using the energy saving. The recent trend is using LED lightning. This paper is the performance analysis of LED and conventional florescent lamps of 22 street lightning load. From the results it can be concluded that LED have reduced power consumption about 40% less not only that capacitors used in LED drivers gives magnificently high power factor near unity. In this analysis we found the power factor improvement of 44.4%. It is also found that harmonic is very low in case of LED as compared to conventional florescent lamp.

Performance evaluation of groundnut shell in a downdraft gasifier

In India total Groundnut production was 7.54 Million Tonnes during 2010-11, approximately 45% - 50% is from Andhra Pradesh, Karnataka and Tamil Nadu. There are many Groundnut oil producing industries in these states. Disposal of these biomass residues is a problem, since it is difficult to burn groundnut shell waste at atmospheric condition. This situation makes people to focus on sustainable energy resources for waste disposal. One of the technique is Gasification, which is a thermo-chemical conversion process that enables conversion of groundnut shell into producer gas which can be used for power generation. As a raw material, groundnut shells have attractive potential for large scale industries and community level enterprises for power generation. With the above Groundnut production, the production potential per ton of waste is calculated to be 4905 kWh/ton and Energy from waste is calculated to be 2013 MW. Optimization has been made to enhance specific calorific value of producer gas in the downdraft gasifier.
