PROCEDURES FOR THE ESTABLISHMENT OF A GAS PROCEDURE WITH A BURNED CONTAINED GAS PROCEDURE BY PREPARING A GAS JUDGMENT AND SETTING UP THIS GAS JUDGMENT PROCEDURE

摘要

The pressure of gas is measured (5, 14) before and after being reduced by a rgulator (7) to which a set-point value is communicated (8) by a stored-program controller (9). The regulated pressure (Pv) is applied to the heater (32) via a number of parallel magnetic valves (21-24) with reference nozzles (25-28). The valves (21-24), normally closed, can be opened individually by the controller (9). The nozzles (25-28) serve as adjustable constrictions selected either singly or in a gp. ADVANTAGE - Predeterminable flow of gas can be established reproducibly with safeguard against possibility of exceeding nominal power rating.
