Research and Application of Wind Cap Renovation Scheme for Circulating Fluidized Bed Boiler
Taking a circulating fluidized bed boiler as the research object,Unigraphics NX software was used to simulate the structure of the air cap inside the boiler,and a modification plan was proposed.Through model analysis,it was shown that the modified air cap can significantly improve the non-uniformity of wind flow inside the combustion chamber.Afterwards,the circulating fluidized bed boiler was improved according to the renovation plan,and thermal tests were conducted.The results showed that the boiler's thermal efficiency increased from 85.71%to 88.34%.
