(5t) УСТРОЙСТВО ДЛЯ СЖИГАНИЯ ТОПЛИВА(5t) DEVICE FOR BURNING FUEL

1 Изобретение относитс к газогорелочным устройствам и может быть использовано в нагревательных и термических печах.1 The invention relates to gas-burning devices and can be used in heating and thermal furnaces.

Известно устройство дл сжигани топлива, содержащее корпус, установленную в нем с.образованием кольцевого канала загруженную с торцов камеру сгорани , снабженную в боковой стенке отверсти ми подачи воздуха , а также встречно расположен ными радиальными топливаными соплами и патрубками дл отвода газов, причем кольцевой канал подключен к источнику воздуха патрубком 1 .A device for burning fuel is known, comprising a housing mounted therein with the formation of an annular channel, a combustion chamber loaded from the ends, provided with air supply openings in the side wall, as well as opposing radial fuel nozzles and nozzles for evacuating gases, the annular channel being connected to the air source pipe 1.

Однако в такой кoнctpyкции камера сгорани жестко соединена с корпусом, а патрубки дл отвода продуктов сгорани выполнены неохлаждаемыми, что приводит к возникновению разрушающих деформаций в процессе работы.However, in this configuration, the combustion chamber is rigidly connected to the housing, and the connections for the removal of the combustion products are made uncooled, which leads to the occurrence of destructive deformations during operation.

По основному авт. св. №,827888 известно устройство дл сжигани топлива , содержащее корпус и установленную в нем с образованием кольцевого канала, заглушенную с торцов камеру сгорани , снабженную в боковой стенке отверсти ми дл подачи воздуха, а также встречно расположенными радиальными топливными соплами и патрубками дл отвода газов, причем кольцевой канал подключен к источнику воздуха патрубком, а патрубки дл отвода газов установлены с образованием кольцевбго зазора в отверсти х дл подачи воздуха и их входные торцы заведены в полость камеры сгорани С 23.According to the main author. St. No. 827888, a device for burning fuel is known, comprising a housing and an annular channel installed therein, a combustion chamber plugged from the ends, provided with air holes in the side wall, as well as counter-arranged radial fuel nozzles and nozzles for exhausting gases, the annular channel is connected to the air source by a nozzle, and the gas nozzles are installed to form annular gaps in the air supply holes and their inlet ends are led into the cavity of the combustion chamber and C 23.

Однако в конструкции известного устройства, даже при наличии равномерного ввода топлива и Воздуха в камеру сгорани , не обеспечиваетс требуемое распределение тепловой нагрузки в объеме камеры сгорани .However, in the design of the known device, even if there is a uniform input of fuel and Air into the combustion chamber, the required distribution of heat load in the volume of the combustion chamber is not achieved.

Claims

This is a result of the interaction of aerodynamic flows of fuel and air, as well as the influence of the end walls of the combustion chamber with a length greater than .2 of the diameter, and is expressed in the fact that the unevenness of the wall temperature reaches more than 15 and, in the final estimate, reduces the service life combustion chambers. The aim of the invention is to increase the reliability of operation by uniformly distributing the heat load while maintaining the stability of the combustion. The target is achieved by the fact that in the combustion chamber between the fuel nozzles there are additionally installed transverse annular hollow partitions tightly adjacent along the perimeter to the chamber wall and communicated by their cavities with the annular channel. FIG. 1 shows a fuel combustion device, a general view (longitudinal section) j in FIG. 2 shows section A-A in FIG. 1. The device for burning fuel comprises a housing 1 and a combustion chamber 3 plugged at its ends with the formation of an annular channel 2, equipped with holes 5 in the side wall k for supplying air, as well as counter-arranged radial fuel nozzles 6 and nozzles 7 for exhaust gases, and the annular channel 2 is connected to an air source by a nozzle 8, and nozzles 7, for exhaust gases are installed with the formation of an annular gap in the holes 5 for air supply, and their inlet ends are in the cavity of the combustion chamber 3- In the combustion chamber 3 between the fuel nozzles 6, transverse annular hollow partitions 9 are additionally installed, tightly adjacent along the perimeter to the wall k of the combustion chamber 3 and communicated by their cavities with the annular channel

2. The combustion chamber is also provided with nozzles 10 and 11 for installation in them, respectively, of the afterburner candle and the combustion control element. The device works as follows. Air enters through pipe 8 into the annular channel 2 and through holes 5 passes into the combustion chamber 3. The gas through the fuel nozzles 6 is directed to the combustion chamber 3, which is divided into a number of individual combustion chambers interconnected by annular partitions 9. The proposed device allows for reliable and efficient operation of the entire device by creating individual combustion chambers with a uniform and close to the value temperature of the wall. Claims device for burning fuel auth. St. No. 827888, which means that, in order to increase reliability by uniformly distributing the heat load while maintaining the stability of the combustion, in the combustion chamber between the fuel nozzles are installed transverse annular hollow partitions tightly adjacent to the perimeter the wall of the chamber and communicated by their cavities with the annular channel.
