Abstract
859,971. Mixing gases. CRYSELCO Ltd. June 26, 1959 [July 3, 1958], No. 21346/58. Class 86 In an apparatus for adding a secondary enriching or diluent gas to a main flow in such proportions that a characteristic of the mixture, such as the calorific value or the Wobbe index, is kept constant, the secondary supply is controlled by a valve which is responsive both to the rate of flow of the primary gas and to the value of the characteristic. The primary flow is controlled by a valve 1 carried by a diaphragm 3 the underside of which is exposed to the pressure of the gas upstream of .the valve 1, and. the upper side to the downstream pressure through pipe 4. Any increase of pressure will therefore tend to open the valve 1 and also move upwards the valve 6 so that the passages 8, 9 through which the secondary gas supply passes are brought more closely into register. The secondary gas supply may also be adjusted by rotation of the valve 6 by the crank pin and link 11, 12 which are coupled to the device for measuring the relevant characteristic of the mixture. The passages 8, 9 may conveniently be of rectangular cross-section (see Fig. 3, not shown). Printed under the Authority of Her Majesty's Stationery Office by Macaulay's Advertising Service. Ltd.
