Spalanie Odpadów W Procesie Skojarzonym Z Produkcją Klinkieru Cementowego - Problem Emisji Zanieczyszczeń, Robert Oleniacz

Robert Oleniacz

The paper presents a review of emissions of main gaseous pollutants (including acidic constituents), some organic compounds (including dioxins and furans), particulates and heavy metals from cement kilns burning waste fuels.

A widely employed method to reduce the cost of cement production is the substitution of traditional fuels used in cement kilns with alternative and waste-derived fuels. Cement industry offers the most acceptable method of waste (especially hazardous waste) thermal treatment and disposal at much lower cost than commercial incinerators. Characteristic for cement kilns high temperatures and long residence time of exhaust gas ensure almost complete destruction of organic compounds …

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 …

Piece Cementowe - Konkurencja Dla Spalarni Odpadów, Robert Oleniacz

Robert Oleniacz

The paper presents the advantages of cement kilns and the possibility of their use for thermal waste utilization. The most common types of waste incinerated in these kilns and the possible degree of replacing traditional fuels with waste fuels have also been characterized. The work also discusses the problem of air pollutant emissions from the process of waste co-incineration in cement kilns. Attention has been paid to the possible increase in the use of Polish cement industry in the waste management, system, especially in the field of energy recovery from solid municipal waste, waste tires and waste from the refinery …
