Title: The operation of circulating fluidized bed boiler on common problems and Solutions
ABSTRACT
Circulating fluidized bed boiler has the advantages of high efficiency, low pollution, low cost and other characteristics. Circulating fluidized bed combustion is between the layer burning and burning between a combustion technology, is the use of fluidized bed combustion, has many advantages: the fuel wide applicability; the combustion efficiency is high; the combustion intensity, uniform temperature distribution; it adopts low-temperature staged combustion, flue gas desulfurization efficiency, SO2 and NOX emissions; the proportion of load regulation; ash comprehensive use of good performance. It is because of these advantages, in recent years our country of circulating fluidized bed boiler has been rapid development. But in our country the circulating fluidized bed boiler operation condition, high failure rate, short operation period problem has become a universal phenomenon. Mainly in the coal feeding system fault, fault, discharging wind chamber leakage etc.. The Qingdao Power Group Limited company two 220t / h circulating fluidized bed boiler operation condition, in the access to a large number of Chinese and foreign science and technology literature data base, in circulating fluidized bed boiler environmental advantages, technical characteristic, carries on the analysis, on operation of circulating fluidized bed boiler in common problems analysis and find the corresponding measures.
