Description

Изобретение относится к области машиностроения. The invention relates to the field of engineering.

Известна энергоустановка, в которой воду нагревают, испаряют и подают вместе с смесью в камеру двигателя внутреннего сгорания. A power plant is known in which water is heated, evaporated and fed with the mixture into the chamber of an internal combustion engine.

Однако такая энергоустановка мало эффективна в связи с низкими параметрами давления, впускаемого в цилиндр двигателя пара. However, such a power plant is not very effective due to the low parameters of the pressure introduced into the cylinder of the steam engine.

Цель изобретения - повышение эффективности энергоустановки. The purpose of the invention is to increase the efficiency of power plants.

Цель достигается путем испарения воды в котлоагрегате, смешения пара с кислородом и топливом, сжигания смеси в цилиндре двигателя внутреннего сгорания и дальнейшего расширения в турбине, эжектирования отработавших газов эжектором. The goal is achieved by evaporating water in the boiler, mixing steam with oxygen and fuel, burning the mixture in the cylinder of the internal combustion engine and further expanding it in the turbine, ejecting the exhaust gases with an ejector.

На фиг. 1 изображена предлагаемая энергоустановка; на фиг. 2 - котлоагрегат. In FIG. 1 shows the proposed power plant; in FIG. 2 - boiler unit.

Энергоустановка содержит гидронасос 1, котлоагрегат 2, камеры 3 и 4 смешения пара соответственно с кислородом и топливом, камеру 5 сгорания двигателя внутреннего сгорания (либо поршневого, либо роторного с дополнительным расширительным цилиндром), турбину 6, охладитель 7, эжектор 8, нагрузочные элементы 9 (например электрогенераторы), источники 10 конденсированной воды. Котел 2 включает в себя ряд последовательно соединенных водоподогревателей 11-13 с гидронасосами 14, 15 между ними, испаритель 16 и пароперегреватель 17 (см. фиг. 2, где В₁, В₂, В₃ - водоподогреватели, И - испаритель, П-пароперегреватель, а - подключение воды, б - подключение пара). Гидронасосы 1, 14 и 15 обеспечивают превышение давления воды в водоподогревателях 11-13, например в уровне В₁ 2 мпа, В₂ 10 мпа, В₃ 20-30 мпа с соответственным увеличением температуры в последних до 200^оС, 300^оС и 374^оС, а в пароперегревателе П до 450-600^оС. Перечисленные параметры пара могут иметь и несколько меньшие значения.The power plant contains a hydraulic pump 1, a boiler unit 2, chambers 3 and 4 for mixing steam with oxygen and fuel, a combustion chamber 5 of an internal combustion engine (either piston or rotary with an additional expansion cylinder), a turbine 6, a cooler 7, an ejector 8, and load elements 9 (e.g. electric generators), condensed water sources 10. The boiler 2 includes a series of series-connected water heaters 11-13 with hydraulic pumps 14, 15 between them, an evaporator 16 and a superheater 17 (see Fig. 2, where B ₁ , B ₂ , B ₃ - water heaters, And - the evaporator, P- superheater, a - water connection, b - steam connection). Hydraulic pumps 1, 14 and 15 provide the excess water pressure in the water heater 11-13, for example at ₁ to 2 MPa, 10 MPa, B _2, B ₃ 20-30 MPa, with a corresponding increase in the temperature in the latter ^to 200 ° C, 300 ^{° C} and 374 ^о С, and in the superheater П up to 450-600 ^о С. The listed steam parameters can have somewhat lower values.

Вода нагнетается насосами 1, 14 и 15 в водоподогреватели 11-13 котлоагрегата 2, испаряется (в испарителе 16) и перегревается (в пароперегревателе 17), смешивается с кислородом и топливом в камерах 3 и 4. Смесь сжигается в камере 5 сгорания, продукты сгорания расширяются в двигателе внутреннего сгорания. Отработавшие газы расширяются в турбине 6, охлаждаются в охладителе 7 и отсасываются эжектором 8, при этом вода конденсируется в источниках 10. Water is pumped by pumps 1, 14 and 15 into the water heaters 11-13 of boiler unit 2, evaporates (in the evaporator 16) and overheats (in the superheater 17), mixes with oxygen and fuel in chambers 3 and 4. The mixture is burned in the combustion chamber 5, combustion products expand in an internal combustion engine. The exhaust gases expand in the turbine 6, are cooled in the cooler 7 and are sucked off by the ejector 8, while the water condenses in the sources 10.
