- Stoker Chain Furnace And Pulverized Coal To Change Circulating Fluidized Bed Boiler Technology Research

The technique of Circulating Fluidized Bed Boiler (CFBB) is a new generation of highly effective and low-polluting technique of clean combustion which was recently eveloped in the international community.Not only the low emission of NOx, the desulfurizing efficiency of 90% and the similar burning efficiency to coal fired boiler can be reached; but the merits of wide fuel adaptive capacity, fine charge adjustability and convenient synthetically utilization of residues are possessed. Accordingly, the technique is widely extended in the commerce.At present, stoker-fired chain-grate boilers and pulverized coal fired boilers were still employed in many heat and power plants in our country.Comparing to install new CFBB, the expenditure would be cut to a half, if the old-fashioned boilers were rebuilt through the technique of circulating fluidized bed. In addition, the rebuilding period was short, and many other effects were also reached , such as: improving the efficiency of the boilers , decreasing the run of boiler, reducing pollution, increasing the capacity of boilers and extending the service lifetime of equipments. The huge economic benefits, environmental benefits, and social benefits resulted from the rebuilding technique.The feasibility of the rebuilding works from old-fashioned boilers to...
