Description

Изобретение относитс к парогене раторостроению и может быть использовано дл получени вод ного пара.The invention relates to a steam generator, a steam generator, and can be used to produce steam.

Известен парогенератор, содержащий Kopiyc, в котором установлены снабженна крышкой вод на емкость, газова камера с размещенным в ней экономайзером, воздухоподогреватель и устройство пульсирующего горени , образованное камерой воспламенени и и-образной жаровой резонансной трубой, выхлопной конец которой находитс в вод ной емкости и подключен к газовой камере, причем газова камера, воздухоподогреватель и камера воспламенени расположены в вод ной емкости l.A steam generator containing a Kopiyc is known in which a gas chamber with an economizer is placed in it equipped with a lid of water, an air heater and a pulsating combustion device formed by an ignition chamber and an I-shaped flame resonance tube, the exhaust end of which is in the water tank and connected The gas chamber, the gas chamber, the air heater and the ignition chamber are located in the water tank l.

Недостатки данного устройства нерациональность компоновки, при- . вод ща к значительньгу габаритам, и св занные с этим излишние тепло ,вые потери.The disadvantages of this device is the inefficiency of the layout, when-. water to large dimensions, and the associated excessive heat loss.

Наиболее близким к предлагаемому вл етс парогенератор, содержащий корпус с размещенной в нем с образованием кольцевой полости камерой пульсирующего горени с резонансным каналом, соединенным с кольцевым газоходом, охватывак цим воздуховод , подключенный к камере и снабженный глушителем, а также экономайзер с опускными трубами, сообщенный по теплоносителю с пароперегревателем vt23.The closest to the present invention is a steam generator comprising a housing with a pulsating combustion chamber placed therein with the formation of an annular cavity, with a resonant channel connected to the annular duct, encompassing an air duct connected to the chamber and equipped with a silencer, as well as an economizer with standpipes communicated by vt23 superheater coolant.

Недостатком такого парогенератора вл етс низка надежность из-за малого использовани теплопередающей поверхности.The disadvantage of such a steam generator is low reliability due to the low use of the heat transfer surface.

Цель изобретени - повышение надеж10 ности путем более полного использовани теплопередающей поверхности.The purpose of the invention is to increase reliability by more fully utilizing the heat transfer surface.

Указанна цель достигаетс , тем, что резонансный канал образован системой параллельных труб, а глушитель This goal is achieved by the fact that the resonant channel is formed by a system of parallel pipes, and the silencer

15 выполнен в виде криволинейных патрубков , расположенных в полости воздуховода и сообщенных своими концами с кольцевым газоходом.15 is made in the form of curvilinear pipes located in the cavity of the duct and communicated at their ends with the annular gas duct.

Кроме того, парогенератор снаб20 жен подключенным к опускным трубам экономайзера и охватывающим камеру пульсирующего горени кольцевыми распылителем с соплами, направленными на трубы резонансного канала In addition, the steam generator is equipped with an economizer connected to the standpipe of the economizer and the annular atomizer with nozzles directed to the resonant channel tubes surrounding the pulsating combustion chamber

25 камеры.25 cameras.
