INVENTION: APPARATUS AND METHOD TO CONTROL PROCESS TO REPLACE NATURAL GAS WITH FUEL OIL IN A NATURAL GAS BURNER INVENTORS: WILLIAM WARREN HOEHING JOHN MAGEE JACKSON EDWARD ROBERT JOHNSON ABSTRACT OF THE DISCLOSURE An apparatus and method to control a process to replace natural gas with vaporized fuel oil whereby fuel oil is mixed with a gaseous diluent and partially vaporized, liquids separated out, super- heated and burned in a natural gas burner without major modification to the burner is disclosed. The control system is: (1) a liquid level controller sensing the liquid level in the separator to automatically control the flow of the fuel oil to the vaporizer, (2) a ratio flow controller sensing the flow of the fuel oil and of the diluent to the vaporizer to automatically control the flow of the diluent to a set ratio of the flow of the fuel oil, (3) a pressure controller sensing the pressure at the vaporizer outlet and downstream overhead to automatically control the heat input to the vaporizer and optionally, -1- (4) a flow control valve set to automatically control the flow of the separator overhead to the burner; also, (5) a temperature controller sensing the temperature of the vapor effluent from the superheater to automatically control the heat input to the superheater. The vaporized fuel-diluent should be superheated to 50-300°F. above the dew point of mixed vapor, preferably 100-275°F. above. The fuel-diluent mixture should be at a steady pressure value between about 5 and 80 psig. as feed to the burner. The preferred diluent is steam. -2-
