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.

It offers the simplest precalciner burner design among the solutions proposed by Fives. The burner is easily customizable: for example, it offers the choice of central or annular gas injection. This burner is dedicated to precalciners that combine multiple horizontal low-power burners (<30MW) to optimize CO and NOx emission reduction.

The main gas channel, with a system of flexible hoses, comes from the traditional M.A.S. burner (Figure 4). The low-pressure primary air in the kiln burner is only used for cooling purposes, because the gas velocity is higher than the primary air velocity at the injection point. This provides effective management of the flame shape by using the ...

The variations are large. Shaft kiln operations are reported at 3.2–4.9 GJ per ton product and rotary kilns at 5.1–9.2 GJ per ton product 3. The benefits of the rotary kiln are, e.g., higher utilization of quarried raw material, different product quality, and higher fuel flexibility.

A rotary kiln (16) fired with pulverized coal as the primary fuel with the firing system including a burner (22) capable of utilizing coal, gas or oil. The firing system and burner are such as to provide particular ratio of burner discharge area to primary air flow for coal firing so as not to contaminate the kiln product during coal firing operation.
