Emission of hydrogen chloride (HCl) from coal combustion is not controlled just like for example sulpfur dioxide emission. But HCl emission is also important, because chlorine content in some types of coal can reach the similar level to sulfur content. In the paper the measurement results of HCl emission to the air during combustion of three types of coal with law content of chlorine were presented. The researches were carried out for a steam pulverized coal boiler (max. boiler efficiency – 430 t/h) during three various loads (respectively 65, 80 and 95 % of maximum efficiency) without flue gas desulfurization. …

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 …

Surface Structure Of Alkylsilylated Hzsm-5 As Phase-Boundary Catalyst, Hadi Nur, Yun Hau Ng, Mohd Nazlan Mohd Muhid, Halimaton Hamdan

The need for cleaner environment concerns motivates the development of more efficient catalytic system. Based on this consideration, recently a novel catalyst named "Phase-boundary catalyst", a bimodal amphiphilic solid catalyst, was proposed. It was demonstrated that the catalytic system containing phase-boundary catalyst required neither stirring to make an emulsion nor addition of a co-solvent to make a homogeneous solution to drive the reaction. The driving force that has prompted this paper is to investigate the surface structure of alkylsilylated HZSM-5 as phase-boundary catalyst. Temperature Programmed Desorption (TPD) of ammonia and, 13C and 29Si MAS NMR spectroscopy were used to elucidate …

Emisja Btx Towarzysząca Produkcji Wyrobów Węglowych I Grafitowych, Marian Mazur, Przemysław Szczygłowski, Robert Oleniacz, Marek Bogacki

The work presents results of direct measurements of benzene, toluene, ethyl benzene and xylenes (BTX or BTEX) emissions to the air from technological processes related with carbon and graphite manufacturing. The most important from all mentioned pollutants is benzene considered as one of the main factor of air pollution in the European Union. The highest concentrations of BTX were found in the fumes emitted from the tanks of liquid raw materials, while the highest levels of their emissions were from furnaces used for baking of green electrodes and other carbon products.

English title: BTX emission from production of graphite and …

Wpływ Wybranych Parametrów Na Wielkość Emisji Zanieczyszczeń Powietrza Z Procesu Wysokotemperaturowego Spalania Odpadów Chloroorganicznych, Robert Oleniacz

Robert Oleniacz

In the paper preliminary analysis of the continuous measurements of the air pollutants emission and other

parameters of high-temperature process of chloroorganic waste incineration (liquid injection incinerator - Vicarb technology) are presented. In the analysis there was taken especially note of the parameters influencing the emissions, which could significantly vary in the incineration system (for example the amount of incinerated wastes) and pollutants like hydrogen chloride, nitrogen oxides and carbon monoxide. Basing the results of the analysis, it was affirmed that chlorine plays an inhibiting role on the formation of nitrogen oxides in the chloroorganic waste incineration system. On the …

Emisja Rtęci Z Energetycznego Spalania Węgla, Marian Mazur, Przemysław Szczygłowski, Robert Oleniacz, Janusz Dańko

In the paper, some results of the measurement of mercury emission from OP-430 boiler working in the Combustion Plant “Kraków S.A.” are presented. The tests were carried out during combustion of various coals and changeable the boiler efficiency. Apart from investigation of mercury emission to the atmosphere (in gaseous and solid phase), total mercury concentration in coal, bottom ash and dust collected in electrostatic precipitators were analysed as well. Thus emission amount could be verified by means of the approximate mercury balance performed for the coal combustion process.

English title: Mercury emission from coal combustion.

Porównanie Poprzedniej I Aktualnej Metodyki Modelowania Rozprzestrzeniania Się Zanieczyszczeń W Powietrzu Opartej Na Modelu Smugi Gaussa, Robert Oleniacz, Marek Bogacki

Necessity of adaptation the Polish law in the field of the environment protection to the European Union law caused to adopt new criterions and methods of the air quality assessment. One of the methods of the air quality assessment is modeling of the substance levels in the air based on the calculation of the air pollutant dispersion in the atmosphere. Thus necessary changes also encompassed the basic methodology applied in our country for many years that had made possible calculation of the air pollution caused by existing and new emission sources. After some modifications the computation method was adopted as …

In the paper some differences between various computational models applied to the atmospheric dispersion modeling were presented. These models each other were compared as regards the expanse-time scale of computation, description way of the wind field and the frame of reference for the air particle moves. Particular attention was paid to the Gauss plume model that was a base for a modeling method of the pollutant levels in the air accepting in Poland as the reference methodology. A general description, applications and limitations of this methodology were presented, as well data essential to the computation, way of the data preparing …
