Czynniki Wpływające Na Skład Spalin I Wielkość Emisji Zanieczyszczeń Z Procesów Termicznego Przekształcania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

The work summarizes factors influencing on air emissions from various full-scale hazardous waste incinerators (rotary kiln, multiple hearth furnace, starved-air incinerator, fluidized bed incinerator, liquid injection incinerator). Air pollutant emissions from hazardous waste incineration can be minimized not only by flue-gas cleaning. There are many factors that influence on flue-gas composition and the quantity of air pollutants formed during incineration: the type, the composition and the quantity of waste, the way of waste introducing to the incinerator, excess air ratio, combustion temperature, retention time of exhaust gases etc. Special attention was paid to the loading of waste and incineration conditions …

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 …

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 …
