1. Positioning of burners. Many companies adopt "light column method" for positioning, accurate control, but inconvenient operation. It is better to use the position scale to locate on the kiln head section. Generally, it is better to control the position slightly to the right of the X axis of the kiln head section or slightly to the fourth quadrant. In special process conditions can do a little fine tuning.
2. Influence of flame Shape on calcining The best flame shape for burner design is the position of axial flow wind and swirling wind at (0.0) (the maximum ventilation rate of each duct at this time), when the flame shape is complete and powerful. Lateral distribution of burners. Flame shape adjustment is accomplished by adjusting the ventilation cross-sectional area of each duct. The ventilation cross-sectional area of axial and swirling winds is maximized. The shape of the flame is obtained through the mutual influence and restriction of the swirling wind and axial flow wind. The stability of the flame shape is achieved through the central wind, which can neither be too large nor too small. To change the flame shape, a stable primary air outlet pressure is needed to maintain the flame shape. The flame shape can be changed by stabilizing the pressure on the burner and changing the ventilation cross-sectional area of each duct. A change in the shape of a specific flame. When adjusting the shape of the flame, to avoid extreme phenomenon, when the flame is too thick, it will be very long, very soft. When the flame is too thin, the flame will be too short, burning into a strip requires the shape of the flame integrity, lively, powerful, which requires our long-term observation and summary of experience.
3. Regulation of normal and abnormal conditions: In normal operation, if the temperature of the kiln firing zone is low, open the inner wind butterfly valve to a large extent and close the outer wind butterfly valve to shorten the flame and increase the temperature before the kiln; When the sintering temperature is too high, it is necessary to open the outer wind butterfly valve and close the inner wind butterfly valve, so as to make the flame elongate, maintain a certain fast turning rate of the kiln, and improve the output and quality of clinker. If found thick kiln stove or ring, should be disposed in time, otherwise it will affect the yield and quality of clinker, into the furnace burner that outside the wind butterfly valve fully open, endogenous wind butterfly valve is short, the center of butterfly valve will open a big wind, make the flame, burning with ward, improve the body temperature, if found burnt with a flat piece of material, certificate after circle has dropped, the burner all back to the furnace mouth position, outside the wind butterfly valve closed small open degree, endogenous wind butterfly valve open big, center of butterfly valve to close small wind, shorten the flame, improve kiln speed, good control of clinker junction temperature, protect the calcining zone kiln. Because there are a lot of factors, should be according to the kiln type and the structure of the ring, the specific situation analysis, as long as the method is reasonable, it is not difficult to deal with.
