| Abstract: | A cold state modeling test is carried out on the model of HG 2008/18.2 YM2 type tangentially fired boilers. The flow field in furnace and in horizontal flue gas pass is measured detailedly using Hot Wire Anemometer. The velocity distribution in the upper part of furnace is investigated, and the forming mechanism of the flue gas velocity/temperature deviation in the horizontal pass is analyzed. It can serve as an important experimental reference for analyzing the cause of the overheating and tube failure of superheaters and reheaters and for decreasing the flue gas temperature deviation in the horizontal pass. Figs 9, table 1 and refs 4. |
