Improvements in means for preventing emission of hot-gases through the poking or charging openings of gas producers
Реферат: 554,519. Preventing emission of hot gases from gas-producers.ROE, W. Feb. 17, 1942, No. 2086. [Classes 51 (i) and 51 (ii)] In a gas-producer the escape of gas and fumes from the poker or charging holes during cleaning or charging is prevented by a screen of gaseous fluid which is delivered across the poking or charging hole, the means comprising a self contained unit which may be temporarily arranged on the producer. As shown in Fig. 1, a bell 1 is provided with a poker hole or charging opening 3 at the top and with an annular chamber 4 supplied with compressed air delivered through apertures 7 below the opening 3. An apertured baffle plate 6 is arranged beneath the apertures 7. Fig. 3 shows a modification in which an apertured ring 9 supplied with compressed air is welded to a ring 10 in turn welded to the top of the bell 1 and the screen of compressed air is delivered through apertures 11 beneath the opening 3. A flat or conical baffle 13 is welded to the bell beneath the ring 9. The apertures 7 or 11 may be arranged so as to deliver the air in intersecting streams or so as to produce spin or eddy in the gaseous medium.
