Abstract: In order to achieve that the overall combustion conditions of the boiler do not change much under high load
conditions, and the overall operation has no major changes compared to before optimization, on the other hand, the burner can
ensure the stable combustion of pulverized coal under 20% rated load, an optimization scheme was proposed for the swirl burner
of a 600 MW boiler, and numerical simulation optimization research was carried out. By comparing the results, it was proposed
that the inner diameter of the concentrator should be appropriately reduced as the optimal scheme.

Key words: boiler; low load; burner; concentration ratio
