In the rotary kiln and support process, use the rotary kiln burner under the following conditions:
(1) Strong fuel adaptability, especially coal, low-quality anthracite coal or can ensure low excess air coefficient complete combustion emissions and minimum;
(2) the flame form of rotary kiln burner can make the whole area and even the thermal radiation of high firepower, which is conducive to the normal development of clinker crystallization and mineral particle dust, prevent the fire core, form stable kiln skin firebrick and prolong the life;
(3) Space aircraft wind ring thermal deformation, ensure the stability of the number of inconsistent, resulting in good shape of the aircraft flame, it is best to use a few small nozzle injection;
(4) Collecting and utilizing technologies to avoid the highest temperature of flame layer, reduce NOx emission of harmful gases, and improve the management ability by distributing the temperature in the combustion furnace;
(5) Adopt flame stabilizer coal, coal amount, feed, fluctuation and influence situation change little, furnace flame is more stable;
(6) Rotary kiln burner structure is simple, easy to adjust, sensitivity, adapt to various satisfaction of different requirements and changes in the furnace, the formation of a variety of flame.
Rotary kiln burner and layered air boldly guide the structural design, can be obtained in the special short-term high temperature so that pulverized coal, efficient energy saving and Eddie, complete combustion, high energy utilization rate, can eliminate the existence of dust, improve working conditions, labor intensity, energy saving and environmental protection, is an ideal food.
Rotary kiln burners to solve this problem, the simplest way to use a compressed air tube, more through the accumulation of dust particles, will often mess up; Or use the steel tube length of the furnace cover to observe the side or monitor the spread of fire Confucius as a fulcrum, the frame, slightly changed or vibration will accumulate dust particles, cleaning. Rotary kiln burner this operation must be qualified, otherwise, careful injury in addition to, when the mouth refractory high temperature produced material softening, slightly negligent or has been damaged, there is a possibility of diluting the discharge of materials - found that the patient damage should be immediately replaced with the existing focus, cannot risk mistakes - a big problem did not appear. The burner will be damaged in a very short time after the injection of materials.
Rotary kiln burner air quality, because increase the use of increased equipment, especially in the furnace opened, mainly not cold, more severe working conditions. However, at present, there are still no major accidents in the use of multi-channel burners in China. Due to the lack of operation experience and ownership structure problems, he gave full play to his advantages and failed to achieve the expected effect.
