The exhaust gases of the turbine are vented to the atmosphere through the exhaust pipe 8 with the throttle valve 9.
Газова турбина 2 св зана трубопроводом 10 с клапаном 11с камерой дожигани 12, котора снабжена форсункой i3. Последн соединена тру:боп{ оврдом 14 с топливным насосом 15 и топливньм баком 5. Камера дожигани 12 соединена трубопроводе с охладителем газов 16, который содержит водоотделитель 17 и распыливаю«ее устройство, забортна вода к которому подаетс насосем 18. Камера Можиглн 12 непосредственно соединена с трубопроводом 19 подачи инерт ных газов в судна (на чертеже не показаны), на котором установлены манометр 20, св занный обратной св зью 21 с дроссельным клапаном 9 и анализатор кислорода 22, воздействующие на клгшаи 23 возвратного трубопровода 24 топливного насоса 15 и на клапан 25 атмосферного трубопровода 26, св занного с трубопроводом пойДачи 19 и его предохранительным клапаном 27. Анс1лизатор кислорода 22 воздействует также на клапан 28 трубопровода подачи 19. Дл удалени инертных газов из трюмов судна компрессор 3 св зан воздухопроводом 29 через зжекто)р 30 и охлс1дитель газов 16 с трубопроводе подачи 19.The gas turbine 2 is connected by pipeline 10 to the valve 11c of the afterburner chamber 12, which is equipped with a nozzle i3. The pipe is finally connected to: bop (tank 14) with fuel pump 15 and fuel tank 5. Afterburner 12 is connected to the pipeline with gas cooler 16, which contains a water separator 17 and sprays its device, the outside water to which we pump 18. 18. The Mojigel 12 chamber is directly connected with an inert gas supply line 19 to the vessel (not shown), on which a pressure gauge 20 is installed, connected with feedback 21 to the throttle valve 9 and an oxygen analyzer 22, acting on the return line 23 the fuel pump 15 and the valve 25 of the atmospheric pipeline 26 connected to the flow pipeline 19 and its safety valve 27. The oxygen detector 22 also acts on the valve 28 of the supply pipeline 19. To remove inert gases from the holds of the vessel, the compressor 3 is connected by an air pipe 29 through ) p 30 and gas cooler 16 with supply pipe 19.
Устройство дл подачи инертных газов в трюмы судна работает следующим образом.A device for supplying inert gases to the holds of the vessel operates as follows.
Газова турбина с генератором 7 установлена на судне в качестве вспо « гательного источника энергии и используетс дл полученЬ инертных газов после окончани разгрузки судна и подачи их с необходимьм посто нным давлением в TPTONOJ последнего без помощи вентил торов. Избыток мошности турбины при этом используетс дл привода мощного насоса 18 охлеикдающей воды.The gas turbine with generator 7 is installed on the vessel as an auxiliary energy source and is used to obtain inert gases after the vessel has been unloaded and supplied with the necessary constant pressure to the TPTONOJ of the latter without the help of fans. Excess turbine power is used to drive a powerful cooling pump 18.
Во врем разгрузки судна вс мощность газовой турбины потребл етс генератором 7, а ее выхлопные газы отвод тс По выпускному трубопроводу 8 в атмосферу. Клапан 11 при этом закрыт, и устройство подачи инертных газов не работает.During the unloading of the ship, the gas turbine's overall power is consumed by the generator 7, and its exhaust gases are discharged via the exhaust line 8 to the atmosphere. The valve 11 is closed at the same time, and the inert gas supply device does not work.

направл ютс в охладитель 16, где также очищаютс от нежелательных примесей и осушаютс в водоотделителе 17, после чего подаютс в трюмы судна по трубопроводу подачи 19.sent to the cooler 16, where they are also cleaned of undesirable impurities and dried in the water separator 17, after which they are supplied to the holds of the vessel through the supply line 19.
Манометр 20 замер ет давление в трубопроводе 19, а обратна св зь 21 привод ща а действие дроссельный клапан 9, регулирует давление в трубопроводе подачи 19 с тем, чтобы поддержать его посто нным, например равиь 1 1,15 кг/см.The pressure gauge 20 measures the pressure in the conduit 19, and the feedback 21 causes the action of the throttle valve 9, regulates the pressure in the supply conduit 19 so as to keep it constant, for example, ravi 1 1.15 kg / cm.
Анализатор кислорода 22 приводит в действие клапан 23, установленный в возвратном трубопроводе 24 топливного насоса 15. Если в трубопроводе подачи 19 окажетс большое содержание кислорода, то расход топлива через клапан 23 ограничиваетс , в результате чего больше топлива будет подаватьс в камеру дожигани 12 чечерез топливную форсунку 13. Когда сдержание кислс ода в газах находитс ниже установленвого значени , то это указывает на то, что в камере доЖиганиЯ 12 происходит ие полное сгорание топлива и газы могут содержать большое количество окиси углерода . Поток Через клапан 23 в св зи с этим увеличитс , в результате чего подача топлива в форсунку 13 уменьшитс .An oxygen analyzer 22 actuates a valve 23 installed in the return line 24 of the fuel pump 15. If the supply line 19 has a high oxygen content, the fuel consumption through the valve 23 is limited, resulting in more fuel being supplied to the afterburner 12 through the fuel nozzle 13. When the containment of the oxygen in the gases is below the set value, this indicates that in the firing chamber 12 there is no complete combustion of the fuel and the gases may contain a large amount of oxygen. ishi carbon. Flow Through valve 23 will therefore increase, as a result of which the fuel supply to injector 13 will decrease.
Анализатор кислорсща 22 приводит в действие также клапаны 28 и 25. . Причем они регулируютс таким образо что газы поступают в отсеки танкера только тогда, когда содержание кислорода будет на1содитьс в установленных пределах. Если содержанке кислорода будет больше или меньше установленного значени , то отработанные газы по трубопроводу 26 вывод тс в атмосферу, причем низкое содержание кислорода, как отмечалось вьвие объ сн етс йзбыточньнч содержанием окиси углерода.The oxygen analyzer 22 also actuates valves 28 and 25.. Moreover, they are regulated in such a way that the gases enter the compartments of the tanker only when the oxygen content falls within the established limits. If the oxygen content is greater than or less than the set value, the exhaust gases through line 26 are vented to the atmosphere, and the low oxygen content, as noted, is explained by the excess carbon dioxide content.
Температура выхлопных газов тур- бины примерно равна . В кгмере дожигани 12 температура газов еще больше повышаетс , что требует большого расхода охлаждающей воды в охладителе газов 16.The turbine exhaust gas temperature is approximately equal. In the kilogram of afterburning 12, the gas temperature rises further, which requires a large flow of cooling water in the gas cooler 16.
Когда предлагаемое устройство используетс дл удалени инертного газа из трюмов судна с помощью воздуха , имеющего соответствующее давление , то клапан 11 закрыт, а камера дожигани 12 и описанные контрольные устройства не работают. Часть воздуWhen the proposed device is used to remove inert gas from the vessel's holds with air having an appropriate pressure, the valve 11 is closed and the afterburner 12 and the described monitoring devices do not work.
