“…The emission ratio of start-up/normal is 1.25 and toxic emission ratio is 1.02 for one operation, which is similar with studies in MSWIs (Neuer-Etscheidt et al, 2006;Tejima et al, 2007;Wang et al, 2007b;. However, HWIs suffer more from shutting down because of maintenance and lack of raw materials, the emission of PCDD/F from start-up might be more serious.…”

“…Grosso et al (2009) found similar PCDD/F formation in a MSWI during start-up with oil. Peak PCDD/F formation was found around 500°C (start-up 2), in agreement with Wang et al (2007b). Combustion conditions were inadequate during both start-up 1 and 2, and the tube wall and heat exchange temperature has not attained the temperature that most suitable for formation of PCDD/Fs during start-up 1, but it has attained the temperature during start-up 2.…”

The PCDD/F emissions from incinerator start-up are a major contributor to the total amount of such emissions, as has been reported in studies of numerous municipal solid waste incinerators. However, very few studies have examined the start-up process at hazardous waste incinerators (HWIs). In this work we studied the emissions of PCDD/Fs and other pollutants, such as PCBz, at the stack during start-up and normal operations in a HWI. We found that the PCDD/F emissions during start-up were greater than during normal operations, and were comparable to the annual emissions during the normal combustion regime. The emissions of PCDD/Fs were highest during start-up when the temperature was around 500°C, reaching 59.5 ng/Nm 3 (5.49 ng I-TEQ/Nm 3 ) when no APCDs were applied. The emission values of PCDD/Fs during start-up with the application of APCDs and during normal operations were very low, which indicates the importance of APCDs when starting up a HWI, as well as before feeding waste. The chlorination degree, the ratio of PCDFs/PCDDs and the congener profiles were also discussed during start-up and normal operations, with the results suggesting different formation mechanisms of PCDD/Fs. PCBz emissions are two or three orders of magnitude higher than those of PCDD/Fs, and 1,2,4,5-TeCBz was the best correlated PCBz used as a PCDD/F indicator in real HWI flue gas.

“…Several authors [39][40][41][42] found that dioxin versus furan emissions during the start-up of a municipal waste incineration plant were greater than under steady conditions. Neuer-Etscheidt et al [39] proposed that the combustion conditions during heat-up combined with residual deposits were sufficient to promote the formation of halogenated products of incomplete [6,19,33,35].…”

“…Start-up procedures have been shown to be significant and important periods in terms of PCDD/F emissions during incinerator operations (Tejima et al, 2007;Wang et al, 2007;Karademir and Korucu, 2013;Lin et al, 2014). According to Wang et al (2007) and Karademir and Korucu (2013), the PCDD/F emissions during start-up procedures could be 2-4 times higher than those of the whole year normal operations (Cheruiyot et al, 2016).…”

“…According to Wang et al (2007) and Karademir and Korucu (2013), the PCDD/F emissions during start-up procedures could be 2-4 times higher than those of the whole year normal operations (Cheruiyot et al, 2016). The elevated PCDD/F emissions during start-up procedures of incinerators have been attributed to incomplete combustion of diesel and feeding wastes, state of cleaning of boiler section as well as furnace temperature passing through PCDD/F formation window inevitably (Wang et al, 2007).…”

Illegal harvesting and recycling of waste cooking oil, also referred to as "gutter oil" in many countries, poses a great food safety threat. Thus, in this study the feasibility of using waste cooking oil as an auxiliary fuel in the furnace of laboratory waste incinerator was evaluated in terms of toxic pollutant emissions. Two fuel blends (W20D80 and W40D60) were blended from varying proportions of diesel fuel (D100), and waste cooking oil (W100) and their physio-chemical characteristics were subsequently determined and compared. Thermogravimetry analysis (TGA) and derivative thermogravimetry (DTG) of D100, W100, W20D80 and W40D60 showed that diesel fuel consist of more volatile short aliphatic hydrocarbons, while the waste cooking oil and its blends had more thermal stable unsaturated long chain molecules. After the de novo synthesis window of 200-400°C, 40% of waste cooking oil and 60% of diesel (W40D60) was injected at around 500-700°C, and reduced the toxicity concentrations of PCDD/Fs and PCBs by an average of 86% and 94%, respectively. This study demonstrated that, by using waste cooking oil as a fuel blend, not only can reduce the possibility of "gutter oil" being put in the food to damage the health of human beings, but also can be recycled as a kind of green fuel to reduce the emissions of persistent organic pollutants (POPs).
