摘要：In the operation process of pulverized-coal fired boiler with DC Type Low-NO, Burner (DCTLB), blades absence results in great changes of performance. According to the absence of five-level blades burner, the performance was studied on the experimental system of DCTLB. Results show that when one blade is damaged, the effect of the fifth blade on resistance coefficient, ratio of rich and lean air flux and concentration rate is least. Three key performance parameters of two blades absence can be widely adjusted. The case of three blades absence must be avoided in practice.
