A bai-zi-shaped primary combustor capable of igniting and stabilizing combustion in the combustor
By designing a shell-shaped burner, the primary air pulverized coal airflow is used to draw in high-temperature flue gas and mix it with gasified gas to form a stable high-temperature zone. This solves the problem of stable combustion when the pulverized coal boiler is running at low load and achieves a stable combustion effect with low cost and low energy consumption.

Abstract
The application discloses a Bazi-shaped primary combustor capable of stable combustion by igniting in a combustor, which is cylindrical in shape and vertically arranged, and is detachable, so that the overall replacement of core components can be realized, and the maintenance of all internal components is facilitated. Specifically, the Bazi-shaped primary combustor comprises a high-temperature-resistant and heat-insulating top cover, a cylindrical shell, a primary air and pulverized coal gas flow injection inlet, a center zooming cylinder or a semi-open center zooming cylinder with a throat pipe, a flue gas and gasification gas outlet, an igniter, an instrument pipe seat and the like.
