Problem Niekontrolowanego Spalania Odpadów I Pozostałości Roślinnych W Obszarze Wiejskim Na Wybranym Przykładzie, Robert Oleniacz, Barbara Bacik

Robert Oleniacz

This paper presents the results of surveys on the problem of uncontrolled burning of waste in domestic stoves and boilers for central heating and open burning of plant residues in rural areas. The questionnaires were conducted among the inhabitants of one of Polish village (Łąkta Dolna), located in the Malopolska province, in the submontane area. The study comprised 80.2% of all households. As is clear from conducted surveys waste were burned in more than 80% of surveyed houses and more than half of respondents admitted to the open burning of plant residues. The percentage of people burning waste and plant …

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 …

Pesticide Waste Incineration In The Wet Process Cement Kiln, Marian Mazur, Robert Oleniacz, Marek Bogacki, Stanisław Słupek

Robert Oleniacz

The presentation discusses the problem of pesticide wastes in Poland that have been accumulated underground in concrete graveyards or bunkers. Their progressive unsealing poses a significant health risk to people due to groundwater, soil and air pollution. There are not many of professional hazardous waste incineration plants in Poland, therefore, the paper proposes the use of cement kiln for thermal treatment of such waste. Polish cement industry is interested in utilization of various wastes (e.g. in the capacity of alternative fuels) in the process connected with the cement clinker production in rotary kilns. High temperatures existing in cement kilns (ca. …

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 1. Informacje Podstawowe, Robert Oleniacz

Robert Oleniacz

A widely employed method of reducing cement production costs is the substitution of traditional fuels with alternative and waste-derived fuels to heat the cement kiln. Cement industry offers the most acceptable method of hazardous waste incineration and co-combustion with significantly lower cost in comparison to incinerators. The high temperatures and long residence times inherent in the operation of cement kilns ensure the almost complete destruction of the organic compounds introduced together with waste fuels. This part of the article presents general characteristic of sort of waste incinerated in cement kilns, way of their charging, advantages and limitations of waste co-combustion …

Spalanie Odpadów Poszpitalnych I Farmaceutycznych W Piecu Obrotowym / Incineration Of Hospital And Pharmaceutical Wastes In A Rotary Kiln Incinerator, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The paper presents selected results of research on hospital and pharmaceutical waste incineration in a full-scale rotary kiln with variable loads of the kiln. As part of these studies measurements of air pollutant concentrations in flue gases and leaching tests of solid combustion products were carried out. Based on these studies, the maximum dose of hospital and pharmaceutical waste was proposed in the mixture with industrial wastes, which does not cause excessive air emissions. The average emission factors for the waste mixture loading were also determined.
