To produce a heat insulator by curing with steam at low temperature, a new technology of using coal ash discharged from pressurized fluidized bed combustor (PFBC) was developed. Effects of various curing conditions on manufacturing of heat insulator were investigated. Results are summarized as: (1) the produced heat insulator mainly consists of calcium silicate hydrates, calcium aluminate sulfate and hemihydrate gypsum, (2) high quality heat insulators were able to manufactured under conditions of temperature 353 K, humidity 80%, curing time 24 hr, (3) the new insulator produced here shows better qualities than that of some commercial brick.
