Title: Triple stage gas-making process
IPC: C10J1/213
Filed: 1937-05-03
Abstract: 497,149. Steaming coke ovens. KEILLOR, J. May 3, 1937, No. 12542. [Class 55 (i)] In a three stage gas production process in a chamber or coke oven plant, coal gas is distilled from an incandescent fuel charge in the oven in the first stage, followed by the production of blue water gas by injecting steam into the fuel at the bottom thereof in the second stage, the final stage comprising the continuation of the steaming whilst supplying liquid hydrocarbon oil into the heated space above the charge to form carburetted water gas. The calorific value of the coal gas is lowered by the addition of the blue water gas but the value is restored to a higher desired value by addition of the carburetted water gas. In an example the three stages run for 12, 4 and 4 hours respectively, producing coal gas of 530 B.T.U., water gas of 300 B.T.U., and carburetted water gas of 465 B.T.U., the average of the gases being maintained at about 465 B.T.U. or at a value to conform with any desired standard. The latter variation may be obtained by the admission of more or less hydrocarbon to the oven or chamber. The hydrocarbons are sprayed into the top of the chambers, preferably in an atomized condition or they may be dropped in by gravity.
