Advantages:

1.Fuels are distributed evenly at the outlet port of burner; reasonable air distribution; proper mixture point of primary and secondary air; the black fire head at the outlet of burner is controlled from 200 mm to 350 mm in order to make sure timely and strong combustion.
2. Well-organized air dynamic field is better for fire, even mixture of coal powder burning and prevention of slag-bonding. Primary air always rotates weakly. Secondary air forms strong swirling rotation through special structure; by adjustment, annular swirling can be transformed into annular straight air in order to reach proper swirling strength. By adjustment of special structure, primary air can also reach a best mixture point. As a result, this product with diffusion type combustion holds good adjustment in order to adapt to various coals.
1. 3. The resistance of primary air is very small. Coefficient of primary resistance is 0.8 to 2. The coefficient of secondary air resistance is 5 to 6. Owing to features mentioned above,this machine can effectively adjust exit gas diffusion angle and re-circulation zone. It is a new efficient and energy-saving equipment which is widely applied to model selection of industrial kiln and boiler designed in our country. At the same time, it is suitable for host with direct injection system, that is the national patent product developed by our company: high efficiency energy saving type fan coal mill;

Products:

Developed from the special swirling coal powder burner of department of energy of the united states, double swirling coal powder burner combines with technical requests of industrial boiler. As a result, manufacture cost is much lower and operation is much easier.
