Fig. 1. Plan of the producer-gas plant. 



2. Section of the gas generator (dimensions in millimeters) . 



3. Side elevation of the gas generator. The air and steam connection 



is fitted with a four-way cock C, by which connection can be 

 made with the blast pipe D, with the opening E to the atmos- 

 phere, or with the pipe F, which carries a steam supply pipe 

 G, with reducing valve, steam gauge, separator, and steam trap. 

 The pipe F opens to the atmosphere by means of a regulating 

 valve H. 



4. Front elevation of the gas generator. For the purpose of flooding 



the ash pit, the water is supplied by the pipe B, in which the 

 rate of flow may be regulated by the two valves C. The water 

 supply pipe has an exit into the ash pit wall opposite the air 

 intake and also through the t/-pipe A, which constitutes the 

 overflow O to the sewer. 



5. Hopper. The essential parts of the charging hopper consist of 



the coal holder A, the cover B, and the valve C. The locking 

 device D prevents the opening of the valve C when the cover B 

 is open, and vice versa. This arrangement avoids the escape 

 of gases when the producer is being charged. The extension 

 of the hopper or of the funnel E prevents filling the gas generator 

 up to the cover plate, which would choke the gas outlet F. By 

 means of this simple device, also, a supply of fuel sufficient for 

 a considerable length of time is maintained in the chamber G 

 in the top of the producer.
