Energy Efficiency in Refuse Derived Fuel Utilization
Journal Title: RECENT - Year 2014, Vol 15, Issue 42
Abstract
Refuse derived fuel (RDF) derived from municipal solid waste (MSW) is an issue of essential consideration for the sustainable management of the waste-to-energy concept. The policy of waste management in Bulgaria is based on the implementation of leading technologies for waste utilization. In the framework of the recent Programme period 2014-2020 of the European Union, an installation for mechanical and biological treatment of municipal solid waste (MSW) have to be constructed in Sofia, which principal product is RDF. Within the same period an installation for RDF derived energy utilization must be implemented at the district heating company "Toplofikacia Sofia EAD", where an electricity and heat cogeneration technology is considered. The present work, aims at obtaining the efficiency of cogeneration in contrast to the conditions of electricity and heat separate production. Thus, the high energy efficiency criterion (ΔF > 10%) was determined, which justifies the choice of the cogeneration technology instead of production of heat only. At present, Toplofikacia Sofia EAD uses mainly natural gas and fuel diversification is required. The implementation of an installation for RDF utilization ensures the fuel diversification for a reasonable period of time, according to the estimated potential of RDF implementation for energy production.
