Description
Изобретение относитс к способам очистки пароперегревательных элементов паровозных котлов на месте их установки при сниженном котловом давлении и с применением промывки и продувки (просушки) элементов паром.The invention relates to methods for cleaning steam superheater elements of steam boilers at the place of their installation under reduced boiler pressure and with the use of washing and blowing (drying) of steam elements.
В процессе работы парового котла трубки пароперегревательных элементов забиваютс отложени ми солей. Отложени получаютс вследствие испарени влаги пара и испарени воды, по вившейс в пароперегревательных элементах в результате бросани . Как в том, так и в другом случа х имеютс растворимые в воде соли и взвешенные накипь иЛи шламмы, которые будут размещены среди растворимых солей.During the operation of the steam boiler, the tubes of the superheater elements are clogged with salt deposits. Deposits are produced due to the evaporation of steam and the evaporation of water that has accumulated in the steam reheater elements as a result of throwing. In both cases, there are water-soluble salts and suspended scale or slurry, which will be placed among the soluble salts.
При применении предлагаемого способа очистки растворимые соли будут раствор тьс , а нерастворимые будут унесены водою.When applying the proposed purification method, soluble salts will dissolve, and insoluble will be carried away with water.
Предлагаемый способ очистки пароперегревательных элементов паровозных котлов состоит в том, что при постановке паровоза на холодную промывку при сниженном давлении пара в котле, примерно, до 8-10 атмосфер, перекрываетс главный запорный вентильThe proposed method of cleaning steam superheater elements of steam boilers consists in the fact that when the steam locomotive is cold-washed with a reduced steam pressure in the boiler, approximately up to 8-10 atmospheres, the main shut-off valve

Затем подачаводы прекращаетс , элементы подвергают нагреванию и производитс кип чение заполн ющей их воды в течение, примерно, 10 минут. После кип чени элементы продуваютс паром открытием запорного вентил до тех пор, пока пар не будет выходить сухим. Вс операци длитс , примерно, 30-35 минут. Пробег между промывками пароперегревательных элементов устанавливаетс в зависимости от качества вод на данном участке.on the dry-steam chamber, the lid opens above the multi-valve regulator, the lid opens above all valves, except the discharge valve, one end of the sleeve is attached to the injector, and the second end is inserted into the hole of one of the regulator head covers, then the superheater elements are filled with water about 20 minutes or until the water comes out clean. The feed is then stopped, the elements are heated and the filling water is boiled for about 10 minutes. After boiling, the elements are blown with steam by opening the shut-off valve until the steam is dry. Sun operation lasts approximately 30-35 minutes. The run between the washings of the steam superheater elements is established depending on the quality of the water in this section.
