Presently, the three-duct burner or the four-duct burner is generally applied to pre-analytical rotary kilns
. The shape of flame is adjusted by means of moderately matching the indraft wind with all the outdraft wind. In case the flame must be shortened in order to focus higher temperature, or in case the speed of burning is kind of slow on account of low-quality coal, one could boost indraft wind and decrease the outdraft wind. But when the temperature around the floor of kiln is substantial subsequently of high-quality coal or significantly also thin coating of kiln, 1 should raise the outdraft wind and decrease the indraft wind as a way to lengthen the flame. However, the too much intensity from the outdraft wind will generate overlong floating rotary kilns
coating which can be liable to coagulation and curling. For this, concurrently, the temperature at the rear of the kiln will likely be unduly substantial. The flame is going to be thick nevertheless quick together with scattered within the event with the excessive intensity of the indraft wind. In these situation, not just will the kiln coating be burned, but also the LED Down Lights Exporters clinker with coarse nodule and yellow-zone clinker will emerge in pressure underneath the violent burning of the flame leading.
In the functional operation, the coiled gum which happens to be made by means of staying burning may possibly become extended when getting lifting, and can not be turned around flexibly and can even grow to be cake-shape materials from time to time. These set out to demonstrate the actual fact the temperature while in the kiln is simply too higher. In the meanwhile, one particular will need to effectively raise the supply of coal and diminish the indraft wind and intensify the outdraft wind to make the flame more time and mitigate the large warmth inside the kiln.
If the duration from the material is very low when getting lifting and goes down along the fire-resistant bricks, the fabric is just not flexible whilst being released with small particle and the fCaO of clinker is substantial, the temperature of kiln must remain very low. In these scenario, a lot more volume of coal really should be provided towards the kiln. Simultaneously, to increase the indraft and also to decrease the outdraft wind is way required to shorten the flame. Then 1 will need to comparatively concentrate the burning zone and enhance the temperature of the burning zone so as to make the clinker nodule typical.
If it's located the local temperature of the kiln of the burning zone is unduly high or kiln coating will come off in significant amount, the burning temperature is unstable and also the flame is shapeless, and the release of flame washes out kiln coating and fireplace bricks. Presently, decrease or shut the indraft wind and the supply of coal and increase the outdraft wind to extend the flame and alter the lighting location and supply the brand new kiln coating following moving coal injection pipe to be able to recuperate the burning problem.
In a term, one really should regularly verify and regulate the temperature and form of flame within the kiln with a view to fulfill the sensible want of creation and prolonging the existence from the kiln.
