Experimental determination of the swirl burner laboratory models hydraulic resistance
Abstract
Performed investigation of pulverized fuel combustion in swirl flows has shown that there are two important groups of influential parameters: fuel and burner characteristics. The most important conclusion of these investigations is that each type of fuel needs a defined burner for its combustion and concrete operating parameters for its optimal work. Optimal operating parameters can be determined only by performing the appropriate experiments. Selection of optimal swirl burner design is dependent on energy loss which is used for air transport through burner. Increasing of swirl intensity is convenient for fuel ignition and flame stability, but energy loss for air transport increases, too. Swirl economy is estimated using hydraulic resistance parameter which represents energy loss due to swirling. In the paper are presented the methods and experimental data of hydraulic resistance determination for three laboratory models of swirl burners for pulverized fuel combustion. In the tangentia...l burner the swirling is accomplished by tangential inflow of secondary air and fuel/air mixture. Axial-blade burner of type 1 enables swirling by a set of 18 blades. Axial-blade burner of type 2 is with a central lead of gas and coaxial lead of fuel/air mixture, primary air and recirculating gases. In movable swirl block burner the secondary air swirling is enabled by 8 stationary and 8 movable blocks fixed at movable and stationary plate. (C) 2012 Published by Elsevier Ltd.
