KFS kiln burner designs combined with our unique cement kiln CFD modelling and experience in solid fuel combustion can help optimise cement kiln production. Cement Our offering includes system modelling and combustion equipment design for alumina flash calciner, fluid bed, and rotary kiln systems for both oil and natural gas.

Our high-substitution-rate kiln burner for alternative fuels firing. Our JETFLEX® burner is a highly flexible kiln burner, designed to produce the best flame shape and lowest NOx emissions for various fuel types and operating conditions. It fires rotary kilns with pulverised coal or coke, oil, natural gas, or any mixture of these fuels.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Thirty years of experience in the operation of KHD PYRO -JET®burners in more than 700 rotary kilns has resulted in safe and reliably designed burners operating in a number of various conditions. How it works The axial air exits the PYRO -JET®burner at high speed via several separate jet nozzles arranged on the perimete r of the burner.

The dynamic technology supports solid, slurry, fluid and gas fuels, at single or multi-fuel operations within the same system. Our Rotary Kiln burners provide improved energy extraction, resulting in lower emissions, better cost efficiency and higher up-time compared to …

Feb 08, 2007· Re: Definition of swirl number of burner. The primary air of a kiln main burner is normally split into "axial" and "swirl" air, with each being a percentage of the total and their sum equalling . The flame shape is adjusted by varying the proportions of axial and swirl air.

"Firing" in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its "as-received" state. With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
