Summary:The invention provides a hydrogen pulverized coal gasification combustion device and method, and relates to the technical field of power generation. A hydrogen burner is used as a stable torch with high rigidity and high temperature, the flame temperature reaches up to 1400-1500 DEG C, pulverized coal in a pulverized coal combustion cylinder makes contact with hydrogen flame, pulverized coal particles are rapidly heated, released and volatilized, the pulverized coal particles are broken and smashed, and the pulverized coal is gasified and combusted. The pulverized coal airflow enters the gasification chamber together with the airflow provided by the air duct after being subjected to primary combustion, the pulverized coal generates combustible gases such as carbon monoxide and hydrogen and activated semicoke in a high-temperature oxygen-deficient environment, and then the combustible gases and the activated semicoke are sprayed into a hearth to form a gas-like combustion torch; the purposes of ignition starti
