Abstract

439,626. Water-gas generators. CARSON, H. J., 310, South 55th Street, Omaha, Nebraska, U.S.A. April 4, 1934, No. 27081/35. Divided out of 439,562. [Class 55 (i)] A carbonizing chamber 18 in the upper part of a water-gas generator is provided with a vertical passage therethrough, which is vented to the surrounding fuel through annular openings 67 formed by a series of spaced overlapping elements forming an assembly 26. During the " blow," air is admitted at level 20, and the CO formed is burned by air supplied through inlets 20<a>, 20b and 20<c>, to obtain a deep high temperature fuel bed as described in Specification 439,562, the blow gases, after heating the chamber 18 externally, escaping through outlet 25. During the " run," steam is supplied through pipe 21, to avoid cooling the lower zone of hot fuel and solidifying the slag. The water gas enters the chamber 18 and heats the coal therein entering the assembly 26 through the openings 67 and passing with the distillates to an upper outlet 51. A cap 30 may be raised or lowered to control the flow through the fuel and assembly as desired. Superheated steam may be supplied to an inlet 127 to blanket the entrance of blow gas into chamber 18, and to assist in carrying off the distillates through outlet 51, or air may be admitted through this inlet preferably during the " blow," the combustion products passing out through the bottom of the chamber 18 to mix with the blow gases in passage 22.
