Полезная модель относится к противопожарной технике, экспериментальному оборудованию лабораторий, в частности, к испытательным стендам, предназначенным для оценки соответствия характеристик огнетушащих средств установленным требованиям путем тушения очага пожара. Огневая камера для определения значения огнетушащей концентрации ГОТВ содержит огнеупорный стеклянный корпус объемом 1 м, состоящий из четырех стенок, потолка и дна, образующих его внутреннее замкнутое пространство, и выполненный с возможностью размещения в нем четырех горелок из нержавеющей стали. Горелки ограждены защитным экраном и размещены во внутреннем замкнутом пространстве огнеупорного стеклянного корпуса на расстоянии 50±5 мм от стенок. При этом две горелки размещены в противоположных углах огнеупорного стеклянного корпуса относительно пола на уровне 10% и по одной горелке на уровнях 50% и 75% от высоты огнеупорного стеклянного корпуса так, чтобы струи газовых огнетушащих веществ из форсунки не оказывали на них прямого воздействия, в центре потолка размещено отверстие, через которое осуществляется выпуск газовых огнетушащих веществ в замкнутое пространство огнеупорного стеклянного корпуса. На дне и потолке размещены вентиляционные отверстия, обеспечивающие вентиляцию и сброс давления при выпуске газовых огнетушащих веществ. Огнеупорный стеклянный корпус выполнен с возможностью установки в нем анализаторов кислорода на высотах 10%, 50% и 80% от его высоты. Технический результат, обеспечиваемый заявленной полезной моделью, заключается в разработке огневой камеры из огнеупорного стекла, которая позволяет вести наблюдение за испытательным процессом с использованием минимального количества ГОТВ. 2 ил.

Fuel nozzle with central body cooling system

Номер: US20120031098A1
Автор: Almaz Valeev, Borys SHERSHNYOV, Leonid Ginessin
Принадлежит: General Electric Co

A fuel nozzle for turbine engine includes a cooling shroud located at the downstream end of the fuel nozzle to help cool the downstream end of the fuel nozzle. The cooling shroud surrounds the exterior circumference of the downstream end of the fuel nozzle. A flow of air is admitted into the cooling shroud and the flow of air travels in the downstream direction through a first passageway which covers the exterior of the fuel nozzle. The cooling air flow then turns 180° and travels in the upstream direction through a second passageway which is located concentrically outside the first passageway. The airflow then leaves the upstream end of the cooling shroud and enters the interior of the fuel nozzle.

The burner also comprises first feed means ( 20 ) arranged to introduce a flow of a first reagent (for example combustion air) into said cavity and second feed means ( 31 ) are arranged to introduce a flow of a second reagent (for example fuel) into the same operating cavity. The first means are configured so as to introduce the first reagent according to a tangential direction, while the second means are configured to introduce the second reagent according to a direction parallel to the direction in which the cavity extends. According to the invention the operating cavity comprises a first portion between the intake position of the first reagent and the intake position of the second reagent. This first portion defines a stabilization chamber of the flow of the first reagent. The operating cavity also comprises a second portion defining a combustion chamber downstream of the intake position of the second reagent.
