1、 Characteristics of lime rotary kiln burner:

1. The pulverized coal burner features easy ignition, fast temperature rise, greatly improved working efficiency, uniform heating of limestone, stable product quality, low raw and over burning rate, and is especially suitable for calcining high activity steel lime;

2. When the coal powder burner is heated, the temperature rise time is shortened, the thermal efficiency is high, and the coal quality requirements are low. The coal type has a wide range of applicability and high economic benefits;

3. The internal temperature field of the coal powder burner is uniform, the heating coverage of the heated body in the furnace is large, and the slag does not stick to the surface of the workpiece, resulting in good product quality;

4. The residence time of coal powder in the high-temperature zone of the coal powder burner is long, resulting in high combustion efficiency. The flue directly emits no black smoke and is in the form of steam like white smoke;

5. The air supply and coal input of the burner can be changed as needed, and the furnace temperature and flame length can be adjusted within a wide range to meet practical needs.

2、 Working principle of lime rotary kiln burner:

The working principle of a coal powder burner is that the coal powder is carried by the airflow and sprayed outward from the fuel pipeline at a certain diffusion angle. The combustion air from the outer neighbor transmits a considerable amount of momentum and moment of momentum. The swirling air on the inner side mixes with the sprayed coal powder airflow and spirals forward at high speed, meeting the high-speed axial flow airflow beam; The insertion of axial flow air beams further enhances the mixing of coal and air (including the surrounding secondary air), and can adjust the degree of flame divergence. It can adjust the length and thickness of the flame as needed to achieve the desired flame shape.
