The aim of the study was to investigate the effects of liquid inhibitor (known as De-dioTM) on the emission of dioxin-furan from medical waste incineration plants.  Various concentrations of De-dioTM solutions were tested on the medical waste incinerator combustion chamber with an injection flow rate of 1.5 L/min. The sampling protocol of US EPA Method 23 was adopted to collect the sample using a modified US EPA Method 5 sampling train. The flue gas emission was collected before and during the injection of the chemical. The result showed that the De-dioTM was able to reduce or minimize the formation of dioxin-furan to meet its regulatory limits. The study illustrates that the higher the concentration of De-dioTM solution, the lower the dioxin-furan emission was observed in the flue gas.

The City

The development of a mobile waste incineration plant designed for the recovery of garbage dumps located near towns and villages, from where the removal of garbage to the city to the incineration plant is not profitable due to the large remoteness of small settlements from the city. The installation has two combustion zones: in the 1st zone, the combustion process of solid municipal waste (MSW) is achieved at temperatures up to 600 °C, and in the second zone – up to 1200 °C. Afterburning of flue gas to reduce the formation of dioxins, furans and soot is provided.

This study investigates the partition of heavy metals in slag from the rotary kiln (SL), second combustion chamber ashes (SCCA), filter cake (FC) from a bag filter and flue gas (FG) emissions (both in particulate and gas phases) of the Istanbul medical waste incinerator (ISTAC). Eleven targeted heavy metals (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, Sb and Tl) in four matrices were analysed for eight different date samples in 2008. The results obtained were evaluated according to the metal species, furnace temperatures and other factors that affect the formation and accumulation of the metals in the incineration cycle. According to the results, combustion temperatures, reactor configuration and waste contents are the dominant parameters determining the volatility and partitioning of metals in the combustion systems. The biggest waste portions were obtained for the SL and the dominant metal species for the SL and SCCA were Cu (505,9±99,3 and 697,4±577,7 mg per kg dry mass for SL and SCCA respectively) and Mn (238,0±154,6 and 199,9±180,4 mg per kg dry mass for SL and SCCA respectively) . In the FC, the dominant species was Cu (166,8±128,1 mg per kg dry mass) and this was followed by Mn, Ni and Hg. It is thought that cement and activated lignite, which were added to the process as adsorbent materials, were affecting the contents of the FC. Metals were divided into particulate and gas phases and maximum concentrations were observed for Ni, Mn and Cr in a particulate phase of FG. Emission factors were considered and mass balance calculations for metals were also conducted in the study.

Dimensional Simulation

A three-dimensional simulation model of the secondary combustion chamber of a waste incineration plant is presented. The model is based on a set of partial differential equations governing the transport of mass, momentum and energy, together with additional equations modelling the turbulence, heat generation by reaction and radiative heat-transfer phenomena. Because it was not possible to resolve the burner region by a grid being fine enough to describe all details and to get a grid-independent solution, profile measurements were made in a pilot-scale combustion chamber using an isotypical liquid injection burner. These results were used in order to find the parameters of the whole simulation. In order to verify the simulation model some results are compared with measurements of temperature and residence-time distribution at a real incineration plant, and two models are given for the description of the burnout behaviour. Finally the non-isothermal model is discussed and a comparison is made between the isothermal model and the non-isothermal model.

Municipal Waste Incineration

Polychlorinated biphenyls (PCBs) have been withdrawn from the market due to their toxicity, bioaccumulation capacity, and persistence. PCBs have been observed to potentially form in combustion processes under appropriate conditions and in the presence of precursors containing chlorine. The study covered a municipal waste incineration plant and an industrial waste incineration plant. The objective of the study was to assess the effect of these objects on PCB accumulation in soil and plants taking into account the distance from the emission object and wind direction. Soil samples were collected from layers: 0-5, 5-10, 10-20, and 20-30 cm. Test plants were collected from the same areas as the soil samples. The highest accumulation of PCBs was found in plants with large leaf area. Around the municipal waste incineration plant, these were Tanacetum vulgare leaves (12.45 ng/g), and around the industrial waste incineration plant–grasses (4.3 ng/g). In the case of soils, the accumulation of PCBs for both kind waste incinerators was similar, reaching approximately 3 ng/g. As the distance from the municipal waste incinerator and industrial waste incinerator increased, the accumulation of PCBs in the soil decreased. For municipal waste incinerator, no effect of wind direction on PCB accumulation in the soil was observed. In the majority of cases, the accumulation of PCBs in soils taken from the leeward side of the industrial waste incinerator was higher than that in soils from the windward side. In soils around the municipal waste incinerator, PCB compounds moved deep into the soil and reached the highest accumulation in the soil layer of 10-20 cm or 20-30 cm. In soils around the industrial waste incinerator, the highest accumulation of PCBs occurred in the soil layer of 0-5 cm.
