secondary air temperature Page 1 of 2

Re: secondary air temperature. If secondary air temperature increases, your kiln oxygen will not decrease. In fact, it may even increase a little bit. Remember that the amount of oxygen drawn into the kiln is given by the action of the ID fan. ID fan temperature should not significantly change when secondary air temp changes.

Cement Kilns: Firing systems

The air-stream passing into the kiln outside the firing pipe is the secondary air, and this supplies the bulk of the oxygen needed for combustion. Although this was not always appreciated in the early days of rotary kiln operation, it is important that the flame should not impinge upon the clinker bed in the bottom of the kiln, or on the walls

Rotary Kiln Systems: Supporting Equipment

All rotary kilns must be equipped with exhaust or flue gas handling equipment, sometimes referred to as a gas conditioning system. This system collects and treats (or “conditions”) any products of combustion, loss on ignition, gaseous emissions, and small particulates leaving the kiln in order to prevent air pollution and control emissions.

Cement Kilns: Rotary Coolers

In the first, ambient air cooled the clinker to below red heat before entering the kiln as secondary air. The clinker then passed through a crusher into the second cooler, with air drawn through by a fan and wasted. Water was sprayed into the upper end, to increase the cooling effect, and also probably to hydrate free lime, which was a major

The air could also be used to disperse the SRF into the secondary air stream to aid ignition and burnout. The burner settings were linked to the cement clinker quality by means of a statistical analysis tool (Partial Least Squares Regression), which showed that the increased dispersion of SRF would increase the alite content of the clinker

Dec 20, 2011· Adjusting your primary and and secondary air on your burners is a whole other conversation. What you're looking for from your burners is flame color. An orange flame is rich with fuel and a blue flame is efficiently oxidized. Adjusting the primary air to get a flame that is blue has given me the best results in most kilns.
