Research on Flue Gas Temperature Distribution in 1025t/h Boiler

Zhuang En-ru;Zhang Gan  
This paper addresses the flue gas temperature iimbalance caused by theresidual swirl of tangential firing in 1025t/h contr0lled circulation boiler. The researchresults of total swirl number ΣSw≈0 at furnace outlet is applied to improve the firing systemdesign. The measurements made in the test indicatO that the average horlzontal flue gastempearture imbalance at the final superheater outlet is less than 50℃ and the differencebetween the max. and min. wall temperatures is within 25℃.
