At this stage, a term of caution needs to be inserted with respect to the primary air temperature. On numerous rotary kilns, preheated Key air is used to promote ignition of the gas also to variety a particular attractive flame. The ignition temperature for different fuels typically utilized on rotary kilns is often as little as 800 File (425 C). For basic safety good reasons, temperatures inside of the first air duct need to as a result be kept effectively underneath this critical stage all the time. This gets to be Particularly significant on coal-fired kilns where the coal dust is combined with the principal air Within the burner pipe. Exceeding this essential temperature could ignite the coal inside the burner pipe with possible disastrous final results. Quite possibly the most possible instances for this adverse pos­sibility are definitely the durations straight away following a hearth has actually been Lower off or lighted during brief kiln shutdowns; which is, when the burning zone remains at an elevated temperature.??flame, are fully ac­ceptable because they point out in unmistakable conditions a given attribute of the flame.
