- Abstract
- Velocity and temperature fields in the sintered material surrounding an embedded cooling coil in a Kaskan type flat flame burner are predicted. An approximate two-dimensional velocity field is obtained in closed form using a potential flow analogy. The velocity profile above the burner surface will be flat if the distance from the burner surface to the plane of the coil is sufficiently large that the coil wake is ameliorated. Quantitative results for this minimum distance are presented. Several approximations to the temperature field are discussed. Detailed temperature profiles are given for the simplest--one-dimensional with uniform velocity--and the most complex-two-dimensional with potential flow velocity field. The influence of the burner and cooling geometries, fuel type and stoichimetry, flow rate, ambient and cooling water temperatures and sintered material properties, are all described by a small set of dimensionless parameters. Optimization of burner performance in terms of these parameters is discussed. It is hoped that the results will be useful in the design of burners for flame structure studies.
