Abstract

Procedure for cooling and heating plastic-viscous liquids, especially soot-containing suspensions, whose flow regime is determined by the Bingham criterion ** (See formula) ** where η represents the plastic viscosity, (see formula) the variation of the flow velocity perpendicular to the direction of flow, τ the local tangential tension, and τ or the limit tangential tension or flow limit, when the liquid or suspension begins to flow, characterized in that, in order to prevent the formation of rigid, non-fluid plugs, the flow velocity of the liquid or of the suspension in the spaces intended for heat exchange is maintained above the total flow cross section, at least temporarily above τo.
