Abstract

Industrial kilns for ceramic tiles production demand thorough control of the firing parameters to ensure uniform product quality. A given temperature profile must be imposed along the kiln length, while spanwise temperature profile should be as uniform as possible at the tiles level at any location. Due to special needs in emerging markets, interest is growing towards the use of gases produced by gasification processes as an alternative to methane. This requires specific burner design and proper re-calibration of the firing parameters. In the present work, computational fluid dynamics is used to analyse an industrial kiln section for different fuels, nominal burner powers, and burner nozzle diameters. The results are given in terms of temperature and velocity fields in the kiln room, and temperature distributions over the tiles floor. It is shown that a sensible combination of the three parameters investigated can lead to satisfactory results, even with gases having poor heating value.
