Analiza Możliwości Ograniczenia Emisji Zanieczyszczeń Powietrza Z Instalacji Spalania Odpadów Medycznych W Tarnowie, Robert Oleniacz

Robert Oleniacz

The paper presents initial research of effects of some factors on the amount of gaseous pollutants formation during medical waste incineration in a two-stage starved air fluidised bed reactor. In the research was included the impact of such factors as oxygen contents in flue gases, frequency of waste loading, momentary mass flow of waste and temperature in the secondary combustion chambers. Measurements showed that the waste incineration in large amount periodically caused excessive emissions incomplete combustion products (CO, HC), especially during wrong operation of the combustion system. The work demonstrated that the essential importance for CO and HC formation reducing …

Metoda Oceny Trudności Oczyszczania I Toksyczności Spalin Powstających Podczas Spalania Odpadów, Robert Oleniacz

Robert Oleniacz

The paper presents a methodology for evaluating the cleaning difficulty and toxicity of combustion gases from waste incineration based on the knowledge of gases composition. This type of evaluation may be applicable to selection or modernization of flue gas cleaning systems for waste incineration plants and to comparative analy-sis of a pollution degree of raw (unclean) combustion gases. In the evaluation of the cleaning difficulty of gases six categories of difficulty have been identified for removal of selected substances or groups of substances. The evaluation is made individually for substances or groups of substances on condition their concentrations in flue …

Termiczne Przekształcanie Odpadów Medycznych W Instalacji Fluidalnej Firmy Seghers – Emisja Zanieczyszczeń Gazowych I Możliwości Jej Ograniczenia, Robert Oleniacz

Robert Oleniacz

The paper presents the results of measurements of concentrations and mass streams of selected components in the flue gases from the thermal treatment of medical waste in the Seghers incinerator based on fluidized bed reactor.

The tests were carried out at the measuring points located both before and after of the flue-gas cleaning system based on the injection of dry hydrated lime and carbon sorbent and a ceramic filter. In this way it was possible to determine the effectiveness of the removal of selected air pollutants in the dry cleaning system. Analysis of the results of measurements made ​​it possible …

Ocena Składu Gazów Odlotowych Z Procesów Spopielania Odpadów Niebezpiecznych Pod Kątem Trudności Oczyszczania I Toksyczności, Robert Oleniacz

Robert Oleniacz

Tightening of the European Union law in the field of the air emission limit values from waste incineration causes necessity for existing and new incineration plants to conform to the standards. It will often involve modernization of the flue gas cleaning system. Proposed in the paper the methodology of evaluation of the combustion gases composition in point of view cleaning difficulty should be useful to this end. Average toxicity factors for hazardous waste incineration flue gases were defined as well. Among other things they can be used in comparative analysis of the air pollutant concentration in the raw gas (before …

Dobór Systemu Oczyszczania Gazów Odlotowych Ze Spalania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

The flue gas cleaning system is usually one of the most costly elements of the installation to the incineration of hazardous waste. Adapting the system to the actual needs could therefore bring obvious economic benefits.

The paper presents the method of the preselection of the configuration of the cleaning system based on knowledge of the level of concentration of selected components of the raw exhaust gas (sulfur dioxide, hydrogen chloride, hydrogen fluoride, total dust, mercury, cadmium and thallium, and other heavy metals). Twelve examples of flue-gas cleaning systems were proposed and extreme concentration values of the substances in the raw …

Emisja Zanieczyszczeń Ze Spalania Odpadów Niebezpiecznych W Piecu Obrotowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The article presents measurement results of air pollutant emissions from incineration of selected hazardous wastes in a full-scale rotary kiln equipped with afterburner and a wet installation for flue gas cleaning. This type of kiln is suitable for thermal disposal of many sorts of wastes, both solid and liquid. Four groups of waste were being incinerated during the tests: coke tars, medical (hospital) and pharmaceutical wastes added to greased cleaning materials, a sawdust and used gloves, varnish and lubrication wastes, as well as waste rubber and resins. The study was performed in order to answer the question: is the process …

Emisja Zanieczyszczeń Ze Spalania Odpadów Ściekowych W Piecu Półkowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The article presents incineration tests of silty-tar sludge produced in the wastewater treatment plant for coke industry. Sewage sludges were incinerated in a full-scale multiple hearth incinerator equipped with a wet flue-gas cleaning system (alkaline scrubber). Measurements of air pollutant emissions were carried out both before and after the cleaning system. The obtained results allow to conclude that the thermal utilization of sewage sludge in this type of installation might be just a little cumbersome for the environment, using the appropriate equipment for the purification of exhaust gases. The paper also specifies minimum exhaust gas cleaning performance that guarantees compliance …

Emisja Zanieczyszczeń Ze Spalania Odpadów Przemysłowych W Piecu Obrotowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The paper presents the results of measurements of the concentration of selected pollutants in the flue gases from the incineration of industrial wastes in a full-scale rotary kiln. The study included three waste mixtures introduced into the kiln: 1) coal tar waste (tar origin of coke); 1) waste paints, varnish and lubricant; 3) resin and rubber waste. The article also assesses the effectiveness of the existing wet flue gas cleaning system (alkaline scrubber) and specifies minimum exhaust gas purifying performance guarantees compliance with European emission standards for waste incineration.

Monitoring Zanieczyszczeń Powietrza Wokół Elektrowni "Jaworzno Iii", Marian Mazur, Robert Oleniacz, Marek Bogacki, Ryszard Kozakiewicz

Robert Oleniacz

The article presents the concept of system of monitoring of air pollution around the Power Plant "Jaworzno III" in Jaworzno (Poland), whose objective is to evaluate the impact of this object on air quality. This system is based on a few measuring points and a mobile station should also allow for the assessment of ecological effects associated with the use of low-emission burners in power boilers (reduction of NOx emission) and run the wet installation of flue gas desulfurization (reduction of SO2 emission). An additional aim of the measurements is to identify the possible effects of a changes in the …

Termiczna Utylizacja Odpadów W Spalarni "Lobbe" W Dąbrowie Górniczej – Problemy Emisji Zanieczyszczeń, Marian Mazur, Ryszard Januszek, Robert Oleniacz

Robert Oleniacz

The paper presents selected results of comprehensive studies of air quality impact assessment carried out for the „LOBBE” incineration plant in Dąbrowa Górnicza (Poland) in 1995. It focused mainly on air emissions problems. Stack concentrations and emissions of selected air pollutants formed during thermal treatment processes of different kinds of waste materials and incinerators is performed. The study covered both sludge and slime incinerated in a multiple hearth furnace and four example groups of waste materials incinerated in a rotary furnace. The research have helped confirm the levels of air emissions as a function of the type of incinerated waste …
