PERFECCIONAMIENTOS EN LOS APARATOS DE EVACUACION DE PARTICU-LAS SUSPENDIDAS EN EL LIQUIDO SECUNDARIO EN CIRCULACION EN TERMOCAMBIADORES TUBULARES.

摘要

Removal of suspended particulate material in the secondary liquid circulated through a vapor generator of the shell and tube type is effected by the arrangement in the shell interior of baffle means defining a settling chamber therein. The baffle means is operative to retard the flow of secondary liquid and to effect an abrupt change in its direction of flow through the settling chamber whereby the suspended particles are caused to gravitate to the bottom thereof. Continuous or periodic flushing of the settling chamber is effected through a perforated blowdown pipe.
