The incinerator was designed for one of PCBs isomers called Arochlorine-1242 (a mixture of 1 % C12H9Cl, 13 % C12H8Cl2, 45 % C12H7Cl3, 31 % C12H6Cl4 and 10 % C12H5Cl5 with average Cl content of 42 %. Arochlorine-1242 is among the most commonly used types of PCBs, especially in power transformers in great plants. The specification of the incinerator was selected according to Theodore and Reynolds [23]. The Arochlorine-1242 incinerator was designed manually and with the help of software. The design principles in different parts of incinerator such as primary and secondary combustion chambers, furnaces, boilers, suppressor devices and air pollution control devices were similar to the incinerator modeled in [23]. Design calculations were performed according to Charles’s law and Dulong’s equation. Table 1 summarizes the specification calculated for the incinerator. The technical specifications presented in Table 1 were used as initial inputs to Fluent model for simulating the incinerator.\nTable 1 The technical specification of the incinerator\nValue Parameter\n2270 (kg/h) Maximum capacity\nC12H7Cl3 Input pollutant\n20,277 (KJ/Kg) Net thermal value\n50 % Excess air\n2.76 m Initial diameter\n11 m Initial height\n0.5 m Inlet and outlet diameter\n2.7 s Initial residence time","divisions":[{"label":"title","span":{"begin":0,"end":25}},{"label":"label","span":{"begin":1112,"end":1119}},{"label":"caption","span":{"begin":1120,"end":1166}},{"label":"p","span":{"begin":1120,"end":1166}},{"label":"tr","span":{"begin":1167,"end":1182}},{"label":"th","span":{"begin":1167,"end":1172}},{"label":"th","span":{"begin":1173,"end":1182}},{"label":"tr","span":{"begin":1183,"end":1211}},{"label":"td","span":{"begin":1183,"end":1194}},{"label":"td","span":{"begin":1195,"end":1211}},{"label":"tr","span":{"begin":1212,"end":1236}},{"label":"td","span":{"begin":1212,"end":1220}},{"label":"td","span":{"begin":1221,"end":1236}},{"label":"tr","span":{"begin":1237,"end":1269}},{"label":"td","span":{"begin":1237,"end":1251}},{"label":"td","span":{"begin":1252,"end":1269}},{"label":"tr","span":{"begin":1270,"end":1285}},{"label":"td","span":{"begin":1270,"end":1274}},{"label":"td","span":{"begin":1275,"end":1285}},{"label":"tr","span":{"begin":1286,"end":1309}},{"label":"td","span":{"begin":1286,"end":1292}},{"label":"td","span":{"begin":1293,"end":1309}},{"label":"tr","span":{"begin":1310,"end":1329}},{"label":"td","span":{"begin":1310,"end":1314}},{"label":"td","span":{"begin":1315,"end":1329}},{"label":"tr","span":{"begin":1330,"end":1361}},{"label":"td","span":{"begin":1330,"end":1335}},{"label":"td","span":{"begin":1336,"end":1361}},{"label":"td","span":{"begin":1362,"end":1367}}],"tracks":[]}
