Process for operating a gas generator
Patent
·
OSTI ID:6208620
A partial oxidation process is described for the production of a raw effluent stream of synthesis gas, reducing gas or fuel gas in a free-flow partial oxidation gas generator wherein a feedstream comprises a liquid hydrocarbonaceous fuel optionally in admixture with a temperature moderator, or a slurry of solid carbonaceous fuel. An oxidant stream comprises a free-oxygen containing gas optionally in admixture with a temperature moderator, and with or without a separate stream of temperature moderator are passed through feed lines provided with flow control means and then through a burner which discharges into the reaction zone of the gas generator. Partial oxidation of the fuel takes place at a temperature in the range of about 1700/sup 0/F to 3000/sup 0/F and a pressure in the range of about 5 to 250 atmospheres; and a stream of hot raw product gas passes down through an outlet throat at the bottom of the reaction zone and is cooled in a gas cooling zone, and soot and/or other matter entrained in the raw gas stream are removed in a scrubbing zone, to produce a stream of cooled and cleaned product gas. The improvement is turning down or up the flow rates for the separate feedstreams to the burner in a predetermined amount to obtain a specified output of raw effluent gas.
