Simultaneous cooling of chemical flows - with amplitude smoothing of steam volume and pressure using feed water

摘要

Process is for the simultaneous cooling of several prod. flows during chemical processes, esp. for utilisation of waste heat of flows for prodn. of satd. steam in several pressure stages. One or more flows are non-stationary, with discontinuous or cyclic variations of the heat. A smoothing of the amplitudes of the amt. and the pressure of the steam takes place, by using externally stored feed water at controlled feed. This is only for the pipes of a steam generator, through which pass prod. of temporarily varying heat. The supply of the complete feed water requirement is limited to the period of surplus heat of the pipes. Preheating of the feed water is by varying heat sources, and only during a period of surplus heat for all generator pipes.
