Air volume: for coal with high volatile content, one more air should be used; Otherwise, the volatiles will not burn quickly and the rotary kiln burner flame will be stretched and cooled. For low volatile coal, less use of a wind, otherwise coal ignition will be delayed, and easy to cause local high temperature.
In the early 1990s, Greco constructed rotary kiln burners for the local cement manufacturing industry and was among the first suppliers to provide the burners needed for changing over the numerous heavy oil and coal firing systems to the cheaper petcoke fuel. From today's viewpoint the company's petcoke burner design was advanced technology.

To keep the coal particles in suspension while being transported from the mill to the bin or burner, a minimum velocity of air passing through the coal pipes must exist at all As a rule of rhumb it is advisable not to let this velocity drop below 30 m!s (6000 ft/min). Since there is a direct relationship between the mill-exit draft and this ...
This paper presents a 3-dimentional numerical study with CFX software on physical field in rotary kiln with multi-air channel coal burner. The effects of some parameters on flame feature and temperature profile were conducted, which provides reference for optimal operation and design of the multi-air coal burner. A thermal measurement was …
