The Application of Regression Analysis in the Characteristics Research of Adjustment to Flue Gas Temperature at Furnace Outlet of CFB Boiler

Abstract:

A type of HG-1025/18.64-L.PM41 circulating fluidized bed boiler (CFB) has been put into production since 2009, a lot of significant experiences have been accumulated by the equipment improvement and operation exploration. To further understand the adjustment characteristics of flue gas temperature at furnace outlet, the operation data of 30 operating conditions have been measured, and also the method of regression analysis is applied to research and analyze the correlative factors composed of boiler load rate, ash content as received basis, volatile content as received basis, net calorific value as received basis, particle diameter of feeding coal, bed pressure, primary air ratio, upper secondary air ratio, lower secondary air ratio and oxygen content at furnace outlet.
