Description

Дл предотвращени отложений сажи и образовани нагара в наровых котлах обычно Примен ют омесь химикатов, содержащую до 90% хлористых солей, преимущественно хлористого натри .In order to prevent soot deposits and carbon formation in steam boilers, a mixture of chemicals containing up to 90% of chloride salts, preferably sodium chloride, is usually used.

В предлагаемом способе борьбы с нагаром в морских паровых котлах используетс морска вода. В растворенных в ней сол х содержитс около хлористого натри , т. е. столько же, сколько их содержитс в упом нутых химикатах.In the proposed method of controlling carbon deposits in sea steam boilers seawater is used. The salts dissolved in it contain about sodium chloride, i.e., as much as they are in the mentioned chemicals.

Способ заключаетс в том, что в топку через форсунку периодически ввод т в распыленном виде некоторое количество морской воды. Впрыскивание .последней производитс во врем работы котла, после соответствующей прочистки топки и при наличии хорощего огн .The method consists in that a certain amount of seawater is periodically sprayed into the furnace through a nozzle. The injection of the latter is carried out during the operation of the boiler, after appropriate cleaning of the furnace and with good fire.

Поступающа в топочное пространство морска вода увлекаетс потоком гор чих газов и испар етс , а выделивщиес из нее хлорсодержащие соединени унос тс в дымогарные трубы, где приход т в соприкосновение с пленкой нагара. При этом под воздействием хлорсодержащих соединений происходит разрущение пленки нагара, котора в виде отдельных кусков уноситс в трубу вм.есте с.газами.The seawater entering the combustion space is entrained by the flow of hot gases and evaporated, and the chlorine-containing compounds released from it are carried to the fire tubes where they come in contact with the soot film. In this case, under the influence of chlorine-containing compounds, the film of carbon deposits is destroyed, which, in the form of individual pieces, is carried into the pipe along with test gas.
