nota Explanation: da quanto vedo sul sito citato, mi sembra di capire che si tratti del "passaggio posteriore" che fanno i gas combusti della caldaia, che vanno nel/nei Super-heater e quindi nell'economizzatore. Questi elementi di solito si trovano dietro (back) la camera di combustione. http://nett21.gec.jp/JSIM_DATA/WASTE/WASTE_3/html/Doc_458.ht... Takuma's fluidized-bed boiler is a single-drum natural circulation boiler consisting of a combustion chamber, a cyclone, a loop seal and a back pass, all with membrane construction. A steam superheater and the main water tube are located in the back pass portion, but there are two types in the construction. Figure 1. When the fuel is rich in chlorine, such as MSW, RDF or waste containing plastics, HCl corrosion must be prevented. As shown in Figure 2, a radiant-cooling zone is added between the cyclone and the steam superheater to protect the latter, maintaining the exhaust gas temperature below 650ºC. |
