[0029] The first combustion chamber 12 is provided with a first air inlet and an oil inlet corresponding to the first air inlet pipe 8 and the oil inlet pipe 10 respectively.

[0030] Specifically, the axes of the first air inlet pipe 8 and the oil inlet pipe 10 are perpendicular to the axis of the first combustion chamber 12. The gas flow and the micro-oil are impacted each other, and then the micro-oil is dispersed by the gas in the first air inlet pipe 8, so that the surface of the coal particles is more easily attached to the micro-oil.

[0031] The first combustion chamber 12 is fixedly connected with a second air inlet pipe 9 and a third air inlet pipe 11 on both sides near the end of the second combustion chamber 13.

[0032] The second air inlet pipe 9 and the third air inlet pipe 11 are both inclinedly arranged on the first combustion chamber 12.

[0033] Specifically, the axes of the second air inlet pipe 9 and the third air inlet pipe 11 are not in the same plane as the axis of the first combustion chamber 12. The air inlet ends of the second air inlet pipe 9 and the third air inlet pipe 11 are both directed to the side of the first combustion chamber 12 near the second combustion chamber 13.

[0034] The first combustion chamber 12 is provided with a second air inlet and a third air inlet, and the second air inlet corresponds to the second air inlet pipe 9, and the third air inlet corresponds to the third air inlet pipe 11.

[0039] Working principle:

[0040] In use, the coal powder is filtered by the filter assembly 7 to remove impurities, and is concentrated by the coal powder concentrator 16, and then enters the first combustion chamber 12.

[0041] Micro-oil and air are respectively introduced into the oil inlet pipe 10 and the first air inlet pipe 8, and since the output ports of the first air inlet pipe and the oil inlet pipe in the first combustion chamber are oppositely arranged, the first air inlet pipe sprays air flow and the oil inlet pipe sprays micro-oil, so that the air flow and the micro-oil impact each other, and then the air in the first air inlet pipe 8 is used to disperse the micro-oil, and then the surface of the coal powder particles is more prone to adhere to the micro-oil.

[0042] At the same time, the second air inlet pipe 9 and the third air inlet pipe 11 deliver air into the first combustion chamber 12, thereby providing sufficient oxygen for the combustion of the coal powder, and since the second air inlet pipe 9 and the third air inlet pipe 11 are not in the same plane as the axis of the first combustion chamber 12, and the air inlet ends of the second air inlet pipe 9 and the third air inlet pipe 11 are both directed towards the side of the first combustion chamber 12 close to the second combustion chamber 13, therefore the air flow sprayed out of the second air inlet and the third air inlet will form a rotating air flow along the inner wall of the first combustion chamber 12 towards the second combustion chamber 13, and the rotating air flow not only continuously sucks the coal powder on the left side of the first combustion chamber 12 towards the side close to the second combustion chamber 13, but also further collides the coal powder in the rotating air flow, thereby ensuring that the coal powder particles without micro-oil and the coal powder particles with micro-oil collide, thereby ensuring that the coal powder and the micro-oil are uniformly mixed, thereby more easily igniting the coal powder, and enabling the coal powder to burn more stably and more fully.

[0043] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
