Description

TWO SECTION GAS TURBOCHENER

The invention relates to railway transport and for the design of locomotives, in particular gas turbines.

Known gas turbine locomotive, the engine of which runs on compressed natural gas. Compressed gas cylinders are placed on the frame of the locomotive and occupy about half its length and have a significant mass (US, patent N_> 5129328, IPC 61C 5/00, 1992).

The disadvantages of a gas turbine are:

- low sectional power associated with the large dimensions of the compressed gas cylinders;

- low fuel supply with a large weight of cylinders;

- increased explosion hazard due to high gas pressure in the cylinders.

Known two-section gas turbine with a tender for heavy petroleum fuel, which is a separate tank car. Fuel is poured into the tank at a temperature of plus 93 ° C; to maintain the temperature, the walls of the tank are equipped with thermal insulation.

The frame of each of the two sections is supported by two triaxial trolleys with wheel sets equipped with traction motors. In one section there is a power unit with a gas turbine engine leading through a traction reducer. and auxiliary generators, a fuel system comprising a pump supplying fuel from a tender tank to a gas turbine combustion chamber. In the second section, there is a control cabin and auxiliary equipment including an auxiliary diesel generator, a tank with diesel fuel, a diesel cooling system, brake compressors, and control equipment. The sections are connected by power cables, control cables, two cooling water supply hoses, a diesel fuel supply pipeline to start the gas turbine engine, and brake hoses. (Article “gas turbine traction: history and prospects”, Lokomotiv magazine Na3, 2005, p. 41)

The disadvantages of this locomotive are:

- the use of heavy petroleum fuels, worsening environmental performance; - the presence of only one control cabin, which requires a turn of the locomotive after each trip (which is impeded by its large length);

- the presence of an auxiliary diesel generator, which required the placement of a stock of diesel fuel and the systems necessary for its operation.

A jet gas turbine locomotive (gas turbo locomotive) is known, which contains a turbojet gas turbine engine with a dual-fuel combustion chamber, a heat exchanger, a gasifier for liquefied natural gas, heated by the heat of hot gas from a gas turbine engine, cryogenic containers for storing liquefied gas inside the body or on the roof of a locomotive (patent RU5. , Cl. 61 C 1 1/06, 2005).

The disadvantages of this locomotive are:

- high noise level;

- low power associated with the placement on one section of a gas turbine engine and containers for LNG;

- increased explosion hazard, as and gas turbine engines and fuel tanks are in one section;

- the difficulty of controlling a locomotive (a locomotive moving due to a stream of gases cannot reverse);

- uneven distribution of axle load due to tipping moment and the presence of several fuel tanks with uneven fuel production from them).

Known two-section gas turbine locomotive containing two traction sections, which are equipped with bodies with a frame and a control cabin, carts with wrapped wheel pairs. In one of the sections there is a power unit, including a gas turbine engine, which drives the traction and auxiliary turbogenerators and auxiliary equipment. In another section there is a cryogenic tank for storing liquefied cryogenic gas fuel, an auxiliary diesel generator. The tank is located, so that the center of gravity coincides (along the vertical axis) with the center of gravity of the section, which does not allow the occurrence of different loads on the bogies during fuel production. The capacity and the power unit are separated by partitions from the control cabins (patent RU M> 2352484 C2, B61C5 / 00, 2007).

The disadvantage of this locomotive is:

- Explosive deterioration ™ due to the location of the cryogenic tank and gas equipment in the body of the locomotive, as a result of which all fuel leaks resulting from operation can accumulate inside the body;

- long downtime of the locomotive for equipment due to the need to send it to the equipment point located at a considerable distance from the base and a long tank refueling time;

- lack of control of the amount of fuel in the tank;

The technical result of the invention is:

- to exclude the binding of gas turbine locomotive operating areas to specific natural gas liquefaction points through the use of removable containers that can be refueled in natural gas liquefaction points and transported directly to gas turbine locomotive operating areas;

- reduce the downtime of a gas turbo locomotive for equipment by changing the empty tank to full;

- improve the accuracy of measuring fuel consumption.

The specified technical result is achieved in that in a two sectional gas turbine locomotive containing two traction sections, which are equipped with bodies with a frame and a control cabin, trolleys with wrapped wheel pairs. In one of the sections there is a power unit, including a gas turbine engine, which drives a traction turbogenerator, auxiliary equipment, a gas equipment unit, which includes a gas receiver and control automatics, an electrical compartment and other equipment necessary to ensure locomotive movement. In another section, a removable container for liquefied natural gas (or other cryogenic fuel), a block of cryogenic equipment with a piston cryogenic pump, a compartment for high-voltage electrical equipment and a compartment with auxiliary equipment are located. The cryogenic tank with thermal insulation for LNG storage is removable in the size of a standard container and is located in an open area with fastening in the form of standard supports for containers. The supports are equipped with special weighing devices that allow you to control the amount of fuel in the tank, both in the parking lot and in motion. Fuel is supplied to the block of cryogenic equipment through a quick disconnect connection that allows you to quickly undock the container and also quickly dock it. Fuel from the cryogenic equipment unit is supplied to the gas equipment unit of the first section through a flexible intersectional connection.
