Rural energy planning depends solely on the existing levels of energy consumption in domestic sector. In India, energy requirements for cooking and water heating depend predominantly on biomass fuels, which are often burnt in traditional stoves (efficiency < 10%), while kerosene and electricity are used for lighting. Decision Support System (DSS) with relevant data helps the decision makers to take appropriate timelier decisions and assist in the evaluation of reliability and the generation of alternatives. This paper presents a conceptual framework for analyzing energy consumption at domestic sector via DSS. The framework is based on material flux, comparative analyses of village level domestic energy consumption patterns across various zones considering regional and seasonal variations. The system with a synergistic integration of software tools will assist decision makers in understanding the process status better and also aid in providing timelier decisions and efficient outputs. DSS is validated with the data pertaining to energy situation of Kolar district. Stratified random survey covering 2500 households distributed uniformly over the district shows that most households still use traditional stoves for cooking (97.92%) and water heating (98.3%).

Laser light exhibits specific characteristics in the energy transfer to high-energy materials (HEMs) leading to subsequent decomposition process. A set-up was established for laser ignition. Induction time is one of the critical parameters of the HEMs used for various applications. During this study, it was experimentally determined for TPE based RDX-propellants, which are potential candidates for low vulnerability ammunition. Laser beam from a solid state pulsed Nd-YAG operating at 1.06 mm wavelength was used as energy source. An interesting observation was, increase in ignition delay on incorporation of glycidyl azide prepolymer and decrease in ignition delay on addition of ballistic modifier.

Microcontroller (MCS-51) based optoelectronic system for the determination of metal and non metal ions

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

M S Walia, S C Jain, P K Mahapatra, Mewa Singh & M L Singla

An optoelectronic system using Microcontroller 89C51 for measurement of concentration, absorption and transmission of inorganic phosphate phosphorous is described. Phosphorous reacts with potassium antimony tartrate and ammonium molybdate solution to form phosphoantimonyl molybdate complex, which on reduction with ascorbic acid forms blue colour. This blue coloured complex shows absorption maxima at 695nm and obeys Lambert-Beer’s law in the concentration range of 0.05-1.00ppm. Tungsten lamp is used as a light source with a grating (600 lines/mm) to obtain a linear spectrum. A sine drive is used along with the stepper motor that can adjust the grating to achieve the desired wavelength (695nm). Silicon photodiode is used as a detector having peak spectral response at 800nm.

Explosion proof motors play vital role in safe operation of industries associated with explosive gas dusts and chemical of all categories and hence deserve special attention. Flameproof (Ex ‘d’) electric motors are used in hazardous areas like refineries, petrochemical, underground coalmines and oil mines installed in Zone I and II. Hydrogen is being used as a process gas in various refineries, thereby increasing the demand of Ex ‘d’ motors for Gas Group IIC area. High Voltage (HV) Ex ‘d’ IIC motors are being manufactured for the first time in India.. CMRI leads in testing of these motors. HV motors play an important role in the economy of India and are also being exported to different countries.

Electrochemical degradation of erythrosine in pharmaceuticals and food product industries effluent

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Rajeev Jain, Meenakshi Bhargava & Nidhi Sharma

Electrochemical behaviour of erythrosine (disodium salt of 9-carboxyphenyl-6-hydroxy-2,4,5,7-tetraiodo-3-isoxanthone) has been studied using platinum and steel foil as working electrode. Controlled potential electrolysis took 6 h for depolarization using platinum electrode, with a significant decrease in colour and absorbance. The rate of reaction was found to be obeying first order rate expression.

Vitrification of MSWI fly ash using Brown’s gas and fate of heavy metals

Municipal solid waste incinerator (MSWI) fly and bottom ash were vitrified at 1450oC, for the first time, using Brown’s Gas. Vitrification of palletized fly ash (fly ash + water glass) results in decrease in leaching of toxic heavy metals (except Pb) to much below the Korean regulatory limit value, though melted fly ash was a poor vitrified product having dark grey appearance. Addition of glass cullet or bottom ash to fly ash increased silica content and decreased the basicity, which lead to good vitrified product having amorphous dark brown glassy structure. As the vitrified ash products of fly ash and its mixtures with glass cullet or bottom ash were found to be non-hazardous and glassy in appearance, they could be considered as construction and road building material in future.

Technique for adsorption of toxic gases on metal and salt impregnated cellulose strips.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Man Singh, Suman Yadav & Sharif Ahmad

Adsorption of CO, NO2, SO2, CO2 gases individually and CO with NO2 on surfaces of transitional metals and their sulfate, chloride and oxide salts of 100m have been studied. The chemical substances were impregnated on the resin + ethyl cellulose blend coated cellulose strips of 8x3 cm2 made of Whatman filter paper 42. The metals and salts (adsorbents) have been impregnated separately on cellulose strip. The dried melamine methylurea formaldehyde polymer resin was blended with ethyl cellulose powder (1:0.05) for higher porosity. The vacant forces of adsorbent develop interaction with gases, as they happen to be the polar and form coordination bond. Thereby weight gain was observed and confirmation was made with IR, SEM and XRF techniques.

Determination of some important emissions of sunflower oil production industrial wastes incineration

 

 

 

 

 

 

Goksel Demir, Semih Nemlioglu , Ulku Yazgic, Erol Erdal Dogan, & Cuma Bayat

Utilization of sunflower hull as an energy source in facility incineration furnaces during the production of sunflower oil might be a noteworthy method. However, this situation leads to some problems in the legal procedures. Although the fuel types are classified in the article Appendix-7 of the Air Quality Protection Legislation (AQPL) of Turkey, the use of sunflower seed hull as an energy source is not classified. In this study, environmental effects of removal of the process wastes by incineration in a typical sunflower oil production plant (also the reduction of these effects) are analyzed. In addition, the possible negative environmental effects of the combustion gases and the energy that is obtained as a result of the incineration are compared. The stack gas emissions that might be produced because of the incineration of about 285,000 t/y process wastes produced in Turkey are discussed in accordance with AQPL of Turkey.
