Refractory heat exchanger with separate fluid channels mfr

摘要

Heat exchanger for sepd. fluids with separate channels for the fluid to be heated and the are to be cooled, comprises a body contg. the channels moulded by casting refractory material which sets at ambient temp. with a shrinkage less than 0.5%, at least one of the channels including at least one bend, the body being completely monolithic. - The refractory material contains fused and cast grains of one of the systems: ZrO2-SiO2, ZrO2-SiO2-Al2O3 and ZrO2-SiO2-Al2O3-Cr2O3.
