Abstract:
Study on char act eristics of star t-up pro cess using ho t flue gas is car ried out in a simulat ed Pr essur ized Fluidized Bed Com bustor ( PFBC ) w ith a similar wat er-co oled dist ributo r and w ind-box config uration to the pilo t scale PFBC bo iler. Coal acceptabilit y is t ested in star ting up t he fluidized bed using hot flue gas based o n four differ ent coals including bitumino us coal, anthr acite, lean coal and g angue blending anthracite. Effects o f par ameter s, such as bed temperatur e w hen coa l is fed, co al feeding rat e, in-bed heat tr ansfer tubes, static bed heig ht, hot g as t emper atur e and flow rat e, on the st art -up pro cess is investigat ed thor oug hly . Var iations of elevation r ate of the bed temperatur e under v ar ious conditio ns ar e also conducted.
