Re: Precalciner

Turk,

A low NOx precalciner has staged combustion at different parts of the precalciner to create a zone with reducing conditions which destroys NOx formed in the burning zone of the kiln.

Best regards

Dr Michael Clark

Re: Precalciner

Dear Turk,

 

Adding to Dr.Clark's Point.The Residence time of inside the Loz Nox calciner would me comparitiviley more and thats what it is made for giving sufficient time to burn out almost whole NOx but with reduced burden (made by fuel feeding in stage by stage).

 

Any comments Dr.Clark?
