Apparatus for introducing a fluid substance into a carrier gas, and method for operating the apparatus

Abstract

Abstract The apparatus has a storage container (2) connected to a compressed gas line (1), the outlet (6) from which storage container opens via a shut-off member (7) into a carrier gas line (10). The shut-off member (7) and the theoretical values of a first pressure regulator (23) in the compressed gas line (1) and of a second pressure regulator (24) in the carrier gas line (10), are controlled by a program control device (33) with a program memory (34), in which a plurality of programs, selectable by means of a selector (37), are stored for introducing various quantities and/or concentrations of substances into the flow of carrier gas. Each program contains time-controlled switching commands for the opening and closing of the shut-off member (7) and two different theoretical values for the first and second pressure regulators (23, 24). <??>The apparatus can be used for selectively introducing various precisely metered quantities of substances and concentrations of substances (quantities of substance per volume of carrier gas) into the flow of carrier gas, for example for descaling loops of different dimensions, and different quantities and/concentrations of substances can be introduced in rapid succession. <IMAGE>
