Abstract: 2750. Kramers, J. C. H., and Aarts, J. G. Feb. 8. Gas producers or generators.- Water gas is made by blowing steam alternately through two generators, each containing incandescent fuel which is covered prior to the steaming with a layer of fresh fuel, and cooducting the gas produced first through two regenerators, one corresponding with each generator, and then down through the incandescent fuel in the other generator. The fuel employed may be coke, hard coal, brown coal or carbonaceous refuse. As a modification, a semi-water gas may be prepared by blowing a mixture of air and steam through a generator containing incandescent fuel, then passing it downwards through a second generator, and finally through a beat-economizer and preliminary air heater. Behind the two generators 1, 2, but at a higher level, are two regenerators 3, 4, communicating by a single chamber 5, which is surmounted by a preliminary air heater 6. For the blowing-up period, the blast enters the economizer 6 by the tube 15, and passes by the tube 17 to the generators, being led by tubes 18, 19, 20, 21 to the spaces above and below the fuel. The heat passes to the regenerators, and the gases escape through the open valve 7 and the economizer 6. When it is seen through the windows 14 that the regenerators are hot enough, the valves are all changed, and fresh fuel is admitted from one of the hoppers 10, 11 to the generator to be used. Steam is then admitted to this generator by the tube 27 or 28 below the bars, and the water gas produced partly gasifies the fresh fuel, the mixture passing through the first regenerator to the chamber 5, and then proceeding downwards through the second regenerator, the second generator and the outlet 33 or 34 to the purifiers. When the temperature falls sufficiently, the valves are again reversed, a fresh blowing period takes place, after which the other generator receives the steam, and so on. To make the semi-water gas, the hot blow and the regenerators are omitted, and a mixture of steam and air is blown into the generator in use. A special fourway cock 37 may be employed instead of using the four hot air inlet valves 22, 23, 24, 25. This consists of a cock 55 operated by a handle 38 moving over a sector 39, and communicating with the four ways 18, 19, 20, 21, so as to open or shut all simultaneously. In addition, the handle is connected by chains 49, 50 to the two gas outlet valves 35, 36 of the generators, whereby they are simultaneously actuated. Further, the lever 38 is extended and its end is limited by a rod 40 to a sliding bar 56, which carries a rod 57 actuating a slide valve 41 in the valve-chest 42. This slide valve governs the admission of steam by the pipes 45, 46 to the unions 31, 32 leading to the generators, and also, when the lever 38 is in its middle position, by the pipe 53 leading to the injector of the boiler. The chain 9 of the valve 7 is also connected by the lever 38. The lever may also be connected with the governor of the motor driving the blower.
