ABSTRACT:
A method to replace natural gas with vaporized fuel oil is disclosed. The method, in general, is mixing the fuel oil with a diluent, such as steam, then vaporizing a portion of the mixed fuel oil in a vaporizer, then separating the liquid from the vapor, then maintaining the vapor at from about 50.degree. to 300.degree. F. above the dew point of the mixed vapor and diluent and preferably maintaining the pressure of the mixed vapor and diluent at about 75 to 150 psig, above the pressure downstream of a valve controlling flow of the vapor mixed with diluent, and burning the vapor in a burner designed for natural gas without major modifications to the burner. The temperature and pressure can be maintained by heat from the vaporizer or by adding heat from a superheater.
