APPLICATION OF A NEW TYPE PULVERIZED COAL NOZZLE AEROTIPTM IN RETROFITTING THE BURNERS ON A 600MW UNIT
The retrofit of burners on boiler of 660MW generating uinit No 3 in Shajiao Power Plant C has been described. On the basis of analyzing the air dynamic behavior testing results of the boiler
a study on the properties of two kind burners has been carried out. It was found that the fundamental causes leading to furnace slagging are: (1) the air flow in the furnace was severely closing to the wall; (2)The actual tangential circle was over large; and (3) the stiffness of primary air flow was insufficient. A new type pulverized coal nozzles Aerotip TM have been used in stead of WR type burners
the problems of furnace slagging and nozzle deformation due to burn-out have effectively been resolved. It is proven that the retrofit to be effective in practice through comparation of boiler efficiency testing results before and after retrofitting.
