Abstract: 11,105. GuÚnot, L. May 14, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Gas - producers. - A water - gas producer is constructed so as to effect automatically the alternate operations of admitting steam or water into the heated fuel, to produce the gas, and air for re heating the fuel. The air enters through tubes 8, 9, Fig. 1, and the waste gases escape through a tube 11 into a flue 10. Each of the tubes carries a water seal 18 which comprises a bell 19, the three bells being connected to a frame, which is suspended from one end of a balance 21. At the other end of the balance is a counterweight 23, and a small tank 24 which communicates, by a flexible pipe 25, with a second tank 26 placed above the bell of a gasometer 15, and is filled with water when the bell is in the lowest position. The water is supplied to the producer through a bent pipe 14 fixed to the casing 2, and flows from a pipe 27, in which is interposed a valve 28 controlled by the balance. In operation, when the producer is heated by the fuel, the balance takes up a position as shown, lowering the bells into the water and opening the valve 28. The water, after passing through the bent pipe, falls on a checker work 13 and is vaporized. The steam descends through a second checker work 12, thereby becoming superheated, down to the fuel. The mixture of gases formed traverses the firegrate 3 and passes through a water seal 17 into the gasometer. The bell rises, and, on it attaining its highest position, the water from the tank 26 flows into the tank 24. This additional weight pulls down the corresponding arm of the balance, the bells are thereby raised, and the valve 28 is closed. The air is then allowed to enter again and the producer is re-heated. No gas is formed during the re-heatiog, and consequently the bell of the gasometer falls. On it reaching its lowest position, the water again fills the tank 26, and the balance tilts over, again lowering the bells 19 and opening the valve. In order that the quantity of water which flows from one tank to the other to actuate the balance may be a minimum, the areas of the two bells controlling the air inlets are together equal to the area of the bell controlling the outlet. By this means the pressure of the water gas upon the bells is compensated. In order to prevent a prolonged re-heating of the producer, such as would occur if the gas consumption wore delayed, the draught of the flue is controlled by a flap or damper 29 which is actuated by the bell of a small gasometer 30, Fig. 2, placed in proximity to the flue. The gasometer receives water gas by a small pipe 31, and the gas is led by a pipe 32 into a bent tube having a bulb 33. The horizontal arm of the bent tube is filled with mercury and extends into the flue. The vertical arm is fitted with a stopper through which passes a tube 34 cut aslant at the bottom and carrying a burner at the top. If the temperature of the flue increases, the mercury expands and closes the pipe 34. Consequently, the bell 30 rises until the flap or damper is closed. The gas may then escape through a pipe 36. The burner is constantly kept alight by means of a bye-pass 37. A valve may be interposed in the gas supply 31 so that the temperature may, to some extent, be regulated. A tray 4, Fig. 1, of water is placed below the grate to keep it cool. Washing, purifying, carburetting, and deodorizing apparatus may be combined with the producer. A fuel hopper may be also used.
