Ocena Efektów Termomodernizacji Budynków Jednorodzinnych. 1. Zmniejszenie Zużycia Ciepła I Emisji Zanieczyszczeń Do Powietrza, Robert Oleniacz, Magdalena Kasietczuk, Mateusz Rzeszutek

Robert Oleniacz

One of the measures allowing to reduce the emissions of pollutants into the air from the housing sector is decrease in the energy demand, which can be most easily achieved by thermal renovations. This paper analyses some possible variants of thermomodernization of a residential building typical for single-family housing construction of the 1970s and 1980s in Poland (replacement of window frames, insulation of external walls, flat roof insulation and all of the above-mentioned measures together with heating system replacement). Each of the considered variants was assessed in respect to the heat demand and emission of basic pollutants into the air. …

Przykładowa Ocena Wpływu Termomodernizacji Budynków Jednorodzinnych Na Zmianę Ich Oddziaływania Na Jakość Powietrza Atmosferycznego, Robert Oleniacz, Magdalena Kasietczuk, Mateusz Rzeszutek

Robert Oleniacz

The paper presents the results of calculations of pollutant emissions to air from the sample of single-family residential buildings (coal-fired) before and after thermal modernization, as well as an assessment of the impact on air quality of the emissions. The analyzes were included the heat consumption for heating, ventilation and domestic hot water preparation. The assessment of the impact on air quality was carried out for an settlement consisting of 60 such buildings using techniques of modeling of the air pollutant dispersion (CALMET/CALPUFF model).English title: The example of assessment of ambient air pollution changes resulting from the thermomodernization of single-family …

Zakład Termicznego Przekształcania Odpadów Komunalnych W Krakowie – Założenia Projektowe I Stan Realizacji Budowy, Mateusz Rzeszutek, Robert Oleniacz

Robert Oleniacz

The aim of this paper is to discuss the design assumptions and to determine the current status of the construction of the Municipal Solid Waste Thermal Treatment Plant (ZTPOK) in Krakow with a capacity of 220 thousand tons per year. This plant, planned to be built by the end of 2015 years, will be an important element of municipal waste management system in the area of the Municipality of Krakow. ZTPOK in Krakow will consist of the following installations: two lines of municipal solid waste incinerators based on moving grate technology, an installation of chemical solidification and stabilization of fly …

Energetyczne Wykorzystanie Stałych Paliw Wtórnych Z Odpadów (Srf) Na Przykładzie Instalacji Współspalania Paliw W Cementowni Chełm, Magdalena Kasietczuk, Robert Oleniacz

Robert Oleniacz

The paper presents the use of Solid Recovered Fuels (SRF) in Chelm Cement Plant (Poland). These types of fuels are produced from non-hazardous waste and can be used for energy recovery in waste co-combustion plants. They are much cheaper compared to primary fuels, so their use in the process of cement clinker burning brings evident economic benefits. Chelm cement plant owned by the CEMEX company is a leader in the use of alternative fuels in Poland. In the years 2005-2011 the amount of co-combustion of alternative fuels in the cement had risen from 107 to 318 thousand tons, and their …

Produkcja Stałego Paliwa Wtórnego Na Przykładzie Przedsiębiorstwa Usług Komunalnych „Empol” Sp. Z O.O. / Production Of Solid Waste-Derived Fuel - A Case Study Of The Enterprise Of Municipal Services "Empol" Llc, Robert Oleniacz, Leszek Rataj, Monika Wyrostek

Robert Oleniacz

The work presents activities of the Enterprise of Municipal Services "Empol" Sp. z o.o. based in Tylmanowa (Małopolska Province, Poland) and the interrelated technological lines for sorting of waste and production of alternative fuels (refuse derived fuels - RDFs) started in 2009 in the Special Economic Zone in Gorlice. The paper also discusses properties of the produced RDFs and their typical applications.

Assessment Of The Impact Of Using Alternative Fuels In A Cement Kiln On The Emissions Of Selected Substances Into The Air, Robert Oleniacz

Robert Oleniacz

The chapter presents the results of analyses concerning the impact of using alternative fuels in one of the Polish cement plants on the volume of continuously measured emissions into the air for the following substances: carbon dioxide (CO2), carbon monoxide (CO), nitric oxides (NOx), sulphur dioxide (SO2), hydrogen chloride (HCl), gaseous and volatile organic compounds expressed as total organic carbon (TOC), and total dust. The analyses covered a 15-month period of the operation of a dry cement kiln, approximately 100m-long, equipped with four-stage cyclone exchangers and a calciner, constituting an additional chamber for waste co-combustion. The results obtained confirmed the …

Odpady Pestycydowe Jako Paliwo Zastępcze W Piecach Obrotowych Do Wypalania Klinkieru Cementowego, Marian Mazur, Robert Oleniacz, Marek Bogacki, Stanisław Słupek

Robert Oleniacz

The clinker burning plant is ideally suited for processing a wide variety of hazardous waste materials. High temperatures existing in cement kilns (ca. 1350-1450 Centigrades in the burning zone) as well as long gas-residence time (ca. 6-10 s) provide potentially excellent conditions for destruction of toxic organic compounds. Non-volatile compounds are retained in the solid phase and built into the clinker. A lot of other (for example acid gases) can also be absorbed by alkaline solid phase. Old pesticide wastes present a big problem in Poland now. They can be use as waste-derived fuels in cement kilns, especially in the …

Zastosowanie Procesów Pirolizy I Zgazowania Do Termicznej Utylizacji Odpadów, Robert Oleniacz

Robert Oleniacz

The paper presents characteristic of pyrolysis and gasification processes and main trends to their application for the waste thermal treatment. Selected examples of the applications and course of these processes as well as sorts of their final products is here also discussed.
