ENERGY MANAGEMENT SOLUTIONS TO INCREASE PERFORMANCE OF A SUPPLIER AND CONSUMER SYSTEM: CASE STUDY FOR AN UNIVERSITY CHP (Papers SGEM2018)

D. Tutica, V.E. Cenusa, P. Tudor, R. Patrascu, E. Minciuc
Thursday 11 October 2018 by Libadmin2018
ABSTRACT One of the main factors that influence the efficient use of cogeneration systems is the heat demand variation. The second influencing factor is generated by the restrictions imposed by the related legislation. Besides this two, the poor stage of the consumer’s insulation and of the (...)


ENERGY VALORIZATION OF POULTRY MANURE THROUGH PRODUCTS RESULTED IN A PYROLYSIS PROCESS (Papers SGEM2018)

L. MIHAESCU, G. LAZAROIU, I. PISA, D. A. CIUPAGEANU, V. BERBECE
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This paper addresses the possibility of using poultry manure pyrolysis to obtain energy-efficient products. Poultry manure pyrolysis is the intended technology of combustion for both ecological and energy generation purposes, obtaining coke and gas fuel. The waste subjected to (...)


LIFE-CYCLE COST ANALYSIS OF RAPESEED OIL- AND ALGAE OIL-BASED BIOFUELS (Papers SGEM2018)

E. Kardasz, L. Onyshchuk , P. Kardasz, V. Pohrebennyk, O. Mitryasova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Currently, new solutions in the field of alternative fuels are being sought after, taking into account the economic and the ecological aspects of their production. Due to the depleting resources of conventional fuels, one of the currently considered new research directions is the (...)


MATHEMATICAL MODELING OF GLUCOSE ELECTRO-OXIDATION IN A SLIGHT ACID SOLUTION AT THE BIOFUEL CELL ANODE (Papers SGEM2018)

I. Arkadeva, E. Fokina, V. Bogdanovskaya, V. Vasilenko, E. Koltsova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In this paper, it was shown that the gold-modified carbon black (XC-72R + 20% Au) is able to electrooxidate the glucose under conditions, which are the most suitable for the work of the laccase-based electrode (pH = 4.5). It was established that oxygen does not participate the (...)


MICRO SMART GRID TO INCREASE THE EFFICIENCY OF ELECTRICAL POWER SUPPLY FOR THE UNIVERSITY CAMPUS (Papers SGEM2018)

S. Budea, L. Mandrea, R. E. Huluba
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The article analyzes the electricity needs of the University Politehnica of Bucharest campus, consisting of 10 faculty buildings and 18 students’ accommodation buildings. This work establishes the maximum power consumption and proposes a solution through a micro smart grid with a (...)


MINI-CHP PLANT ON THE BASIS OF THE METHANE AIR CONVERSION REACTOR AND ELECTROCHEMICAL GENERATOR (Papers SGEM2018)

A. M. Dubinin, S. E. Shcheklein
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Synthesis gas for an electrochemical generator was produced in a thermochemical reactor with autothermal air conversion of methane (natural gas). Based on thermal balances of the reactor, a battery of SOFCs and a boiler-utilizer (BU) for heating primary and secondary air, cathodic air (...)


MODEL PREDICTIVE CONTROL APPLICATION FOR A BATTERY ENERGY STORAGE SYSTEM IN A WIND POWER PLANT (Papers SGEM2018)

D. A. Ciupageanu, G. Lazaroiu, L. Barelli
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Lately, high penetration of intermittent renewable energy sources into power systems requires, besides efficient technologies employment, developing adequate control strategies to improve their performance. Given that their operation flexibility is constrained by short timeframe of (...)


MODELING OF METHANE-TANK WORK WITH AIRLIFT IMMIXTURE (Papers SGEM2018)

V. Dmytriv, R. Kochan, М. Hornostai, T. Bubela, V. Yatsuk
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The anaerobic fermentation of biomass in methane-tank during the biogas production is considered. The process of individual bubbles lifting upwards and its simultaneous interaction with solid particles with mixing of the nascent substrate is analyzed. The forces acting on the bubble (...)


MODERN CONICAL TUBES FROM ALUMINUM INTENDED FOR LIGHTWEIGHT STREAMING LAMPS FOR LED STREET LAMPS (Papers SGEM2018)

R. Kruzel, P. Helbrych
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The paper analyzes the use and production of modern lighting columns made of aluminum for street lighting. The modern process of manufacturing conical pipes by means of the box rolling method on a special laboratory mill built for this purpose is presented. The study performed the (...)


NEW EVOLUTIONS, DIRECTIONS AND TRENDS IN CONVERSION AND STORAGE OF RENEWABLE ENERGIES (Papers SGEM2018)

C. Cristescu, L. Dumitrescu, V. Dulgheru, C. Dumitrescu
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The special resources of renewable energy identified in Romania have generated far more extensive concerns and research on their capture, storage and use. The first part of this paper presents a couple of renewable energy sources, technologies for their capture and conversion, and (...)
