Abstract:
A solid-fuel-fired burner that suppresses a high-temperature oxygen remaining region formed at the outer circumference of a flame and that can decrease the amount of NOx eventually produced is provided. A solid-fuel-fired burner that is used in a burner section of a solid-fuel-fired boiler for performing low-NOx combustion separately in the burner section and in an additional-air injection section and that injects powdered solid-fuel and air into a furnace includes a fuel burner having internal flame stabilization and a secondary-air injection port that does not perform flame stabilization, in which the air ratio in the fuel burner is set to 0.85 or more.
