Description
При входе камер 10 ротора 2 в воздушный отсек 8 их торцы на гор чей стороне ротора открываютс в этот отсек и некоторое врем остаютс открытыми на холодной стороне ротора 2 в газовый отсек 7, поскольку плита 3 на гор чей стороне ротора 2 смещена в сторону газового отсека 7. В св зи с образованием резкого перепада давлени на противоположных торцах камер 10 ротора 2 воздух из воздушного отсека 8 через торцы камер 10 ротора 2 на гор чей стороне последнего с большой скоростью устремл етс в камеры 10 ротора 2, вытесн наход щиес в них дымовые газы через открытую часть торца этих камер 10 в газовый отсек 7. Как только торцы камер 10 ротора 2 на холодной стороне ротора 2 окажутс перекрытыми основной уплотнительной плнтой 4, скорость потока через камеры 10 резко упадет, а по мере их перекрыти дополнительной уплотнительной плитой 11 скорость потока будет снижатьс почти до нул . При дальнейшем перемещении ротора 2 в камеры 10 устремл етс воздух из воздушного отсека 8, вытесн дымовые газы через зазор 12 в газовый отсек 7.When chambers 10 of the rotor 2 enter the air compartment 8, their ends on the hot side of the rotor open into this compartment and remain open on the cold side of the rotor 2 for some time in the gas compartment 7, since the plate 3 on the hot side of the rotor 2 is shifted towards the gas compartment 7. In connection with the formation of a sharp pressure drop at the opposite ends of the chambers 10 of the rotor 2, the air from the air compartment 8 through the chambers 10 of the rotor 2 on the hot side of the latter rushes into the chambers 10 of the rotor 2 at high speed, displacing the smoke gas through the open end of these chambers 10 into the gas compartment 7. As soon as the ends of the chambers 10 of the rotor 2 on the cold side of the rotor 2 turn out to be blocked by the main sealing plate 4, the flow rate through the chambers 10 will drop sharply, and as they overlap with an additional sealing plate 11, the flow rate will decrease to almost zero. Upon further movement of the rotor 2 into the chambers 10, the air rushes from the air compartment 8, displacing the flue gases through the gap 12 into the gas compartment 7.
Смещение торцовой уплотннтельной плиты , размещенной на гор чей стороне ротора , отпосктельно основной плиты на холодной стороне в направлении газового отсека с получением угла взаимного перекрыти плит гор чей и холодной сторон ротора меньшего, чем угол сектора камер ротора, позвол ет уменьшить золовые отложени в набивке ротора за счет повышени скорости замещени дымовых газов в камерах ротора .The offset of the end plate located on the hot side of the rotor, on the cold side of the main plate in the direction of the gas compartment with obtaining the angle of mutual overlap of the hot and cold sides of the rotor smaller than the angle of the rotor chamber sector, reduces the ash deposits in the rotor packing by increasing the rate of replacement of flue gases in the rotor chambers.
