✦ Synopsis

The scope for energy conservation in a ceramic factory was studied. It was found that the sensible heat of the flue gas from kilns could be used to heat the casting shop. A pebble bed waste heat regenerator was chosen to collect the sensible heat of the flue gas. Experiments were performed on a pilot plant scale pebble bed to study its characteristics using a flue gas stream whose temperature and composition were similar to the factory conditions. The results of the heating cycle showed that 14 500 kcal h\ of heat can be collected from flue gas in a 0•126 m bed. This information was used to design a complete retrofit system. Financial analysis of the proposed project showed that it has a pay-back period of 15 months. 1997
