摘要: A tangentially-fired furnace for the burning of anthracite is disclosed. The furnace may contain a boiler with a chamber having four corners. Four burner groups located at the four corners may be configured to eject pulverized coal flow into the chamber for combustion, in order to form a single fireball substantially at the center of the chamber during combustion. Each burner group may contain a first burner which includes primary-air/rich-portion nozzles for ejecting rich-portion coal flow into a lower section of the chamber, and a second burner which includes primary-air/thin-portion nozzles for ejecting thin-portion coal flow into a higher section of the chamber.
