Exactly the same or comparable reaction can occur which has a unexpected substantial drop in secondary air temperature, or when excessive air (massive percentage of excessive air) is launched into your kiln by excessively higher I.D. fan pace. Each of such occurrences can result in a decrease in flame temperature.
This warm secondary air stream enters the kiln from The underside, and moves upward inside a curved route towards the axis in the flame a few ft earlier the burner nozzle, the place it begins to mix Along with the fuel-Principal air stream. An additional component influencing flame direction would be the mechanical condition of the principal air pipe nozzle. Due to higher temperatures prevailing underneath ordinary operating situations inside the burner hood spot, this Major air pipe nozzle is very prone to warping and distortion, causing uneven envelopment of primary air across the gas jet triggering erratic flame designs and course.
This is why, the new air duct on the coal mill is supplied with a safety ambient-air inlet gadget that allows, by means of a damper, tاe combination of very hot with cold air, and so controls the coal-mill temperature in just Harmless boundaries.
