【Abstract】 With respect to the combustion stability features of pulverized coal fired boilers a variety of measures are proposed to achieve the stable combustion of pulverized coal. Categorized into four aspects, such measures are based on a pulverized coal burner of stable combustion type, dense sparse pulverized coal combustion, proper consideration of the effect of secondary air on the primary air ignition, and a tangential circle formed in the boiler. The results of application of these measures on 670 t/h, 420 t/h and 220 t/h boilers are also presented in the paper.更多还原
