Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides an ignition for boiler combustion, includes air spout pipe 1, air spout pipe 1 right-hand member is connected with combustion chamber 8 through

connector

2, 8 right-hand members of combustion chamber are connected with flame projecting head 5 through flange 4, be provided with ignition chamber 10 in the combustion chamber 8, be provided with powdered coal pipe 9 in the air spout pipe 1, powdered coal pipe 9 right-hand member stretches into in the ignition chamber 10, gasification oil gun 3 and igniter 7 are installed respectively to wall about the combustion chamber 8, gasification oil gun 3 and igniter 7 output stretch into in the ignition chamber 10.

Pulverized coal is sprayed into the ignition chamber 10 from the pulverized coal pipe 9, airflow is sprayed out of the air spraying pipe 1 to guide the pulverized coal to move, gasified oil mist is sprayed into the ignition chamber 10 through the gasified oil gun 3, an igniter 7 ignites the oil mist in the ignition chamber 10, the pulverized coal and the oil mist are mixed and ignited, and the gasified oil mist and the pulverized coal enter the flame jet head 5 under the action of the airflow to achieve ignition operation.

The air injection pipe 1, the combustion chamber 8 and the flame-throwing head 5 are arranged in a cylindrical shape, and the diameters of the air injection pipe 1, the combustion chamber 8 and the flame-throwing head 5 which are arranged in the cylindrical shape are sequentially increased, so that the pulverized coal and the airflow quantitatively flow into the burner at a high speed.
