Flame Adjustment Of Rotary Kilns

The a few and four air ducts are commonly witnessed in the precalciner kiln as well as the flame profile is modified by means of the advisable distribution from the inflow air and outflow air.If there is a must shorten the flame to centralize the high-temperature zone or even the burning fee in the inferior coal is slower, it's necessary to create inflow air and lessen the ball mill.When the coal assumes much better top quality or even the pores and skin from the rotary kilns is too thin and it really is greater to elongate the flame given that the higher temperature with the surface area of kiln human body is really a fact, the outflow air really should be extra and the inflow air will be decreased.Nevertheless, an exceedingly enhance about the outflow air could lead towards the overlong flame that can produce an overlong kiln skin.At the same time the end in the rotary kiln will be inside a standing of large temperature.If there is an around increasing on inflow air, flame profile might get a form of thickness, shortness and dispersion.In this scenario, the skin of rotary kiln will likely be very easily burnt and also the clinker might be incompletely burnt and can be produced with an unqualified significant size.If there sticky supplies of strap is shaped along with the shape is increased to ensure the rolling of supplies is not that flexible and at times there's cake shape created, it is the indication the temperature in the rotary kiln is just too higher.Then it truly is time to effectively decrease the degree of coal and lower the inflow air and boost the outflow air to equilibrium the higher temperature of kilns.If one observes which the clinkering of resources are of very low height and fall along the surface of firebrick along with the scattered supplies is of no stickiness and of tiny dimensions, it really is an explanation the temperature of the clinkering zone is decrease than normal standard.Then the measure taken the following is usually to create coal and improve the inflow air and decrease outflow air for this reason to shorten the flame and centralize the clinkering zone, that will boost the temperature of clinkering zone and normalize the clinker dimensions.If the partial temperature of clinkering zone of kiln body rises over common amount or there exists an huge falling of the kiln pores and skin, the unstable temperature of clinkering, unwanted flame profile as well as the washing of kiln pores and skin by flame are evident.Then it really is time for you to reduce or even shut the inflow air, minimize the coal employed in the head of kiln, and include the outflow air to prolong the flame or eliminate the injection pipe, alter the fire point, renew the kiln pores and skin and get the clinkering again to typical trace.In a phrase, the interior temperature and flame profile should certainly be in standard observation and adjustment to satisfy the need of useful creation and extend the life services with the rotary kilns.
