The gas turbine with multiple independent combustion chambers provided by the utility model is simple in structure, and capable of consuming low-heating-value gas without polluting environment. The gas turbine with multiple independent combustion chambers comprises a gas compressor and a turbine. The gas turbine with multiple independent combustion chambers is characterized in that a gas outlet of the gas compressor is connected with two or more combustion chambers, and all the combustion chambers are all connected with a gas inlet of the turbine.
Description
Technical field
The utility model belongs to the gas turbine technology field, and specifically, the utility model relates to a kind of many bodies independent combustion chamber gas turbine.
Background technique
Existing gas turbine, as: the light-duty or heavy duty gas turbines such as GE, Siemens, Mitsubishi, as shown in Figure 2, they are all with after air and fuel gas premix after gas compressor 1 compression, directly enter 4 burnings of independent firing chamber, then enter turbine 6 and do work, the rotor banding dynamic pressure mechanism of qi 1 by turbine 6 rotates together, and the chemical energy in fuel is transferred to mechanical energy.This gas turbine is applicable to rock gas, light oil, heavy oil, high heating value gas etc.
At present, resource is day by day deficient, and rock gas, light oil, heavy oil, high heat value gas are limited, but low heating value fuel gas but and have no lack of; And if use low heating value fuel gas, in order to guarantee to fire the power of machine, must increase the consumption of low-BTU gas, if present gas turbine uses fuel gas with low heat value, the consumption that will make fuel gas with low heat value is 4～5 times of rock gas, and this has caused the flow of low-BTU gas in the firing chamber to increase several times; Increase due to the low-BTU gas flow, can cause the increase of fuel gas jet velocity, make the fuel gas with low heat value of calorific value about 3000 kilocalories/cubic meter: as coke-stove gas, blast furnace gas, biogas etc., and calorific value is at the steel mill of 2500 kilocalories/cubic meter left and right, the coal gas that the coke-oven plant produces, all can not be under such condition normal combustion, the flame-out and phenomenon of not working easily appears in the combustion machine.Simultaneously, gas turbine can not burn under normal combustion condition, also easily produces the problem that carbon monoxide emission exceeds standard.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, can use fuel gas with low heat value, many bodies independent combustion chamber gas turbine free from environmental pollution.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, and the utility model comprises gas compressor and turbine, it is characterized in that: the air outlet of gas compressor is connected with two or more firing chambers respectively; Institute's combuster all is connected with the suction port of described turbine.
As a kind of preferred version of the present utility model, place, described gas compressor air outlet is provided with the plenum of calming the anger, and the suction port place of described turbine is provided with the turbine plenum.
As another kind of preferred version of the present utility model, between described gas compressor air outlet and firing chamber, and all be connected by metallic conduit between the suction port of firing chamber and turbine.
The beneficial effects of the utility model: 1, the utility model can improve on the basis of existing gas turbine, by setting up the form of firing chamber, realizes using the purpose of low calorie fuels, and simple in structure, production and processing is convenient.
2, the utility model is by increasing the quantity of firing chamber, can make air mean allocation after compression in a plurality of firing chambers, the flow velocity of gas and the flow of combustion gas all are reduced for the part of former flow velocity, do time in advance for burning provides good, combustion temperature and combustion space; Like this, make low-calorie combustion gas fully burning in the firing chamber; Then together flow to turbine and do work, realized the purpose that gas turbine uses fuel gas with low heat value to do work.
3, the utility model can make low-calorie combustion gas fully burn, and when having reduced CO (carbon monoxide converter) emission, has also saved a large amount of rock gases, light oil, heavy oil or high heat value gas; And, by generating electricity with fuel gas with low heat value, also can save a large amount of coal, reduced the discharging of the harmful gas in coal, reach the purpose of energy-saving and emission-reduction.
4, the utility model is by setting calm the anger plenum and turbine plenum, thereby guarantees by even, stable being distributed in each firing chamber after gas compressor pressurized air; Can guarantee from stable the entering in turbine of the high-temperature gas of each firing chamber by the turbine plenum, thereby reach the purpose that makes the turbine stable operation.
5, between the utility model gas compressor air outlet and firing chamber, and all be connected by metallic conduit between the suction port of firing chamber and turbine; Can support gas compressor, firing chamber and turbine by metallic conduit, improve the integral rigidity of gas turbine, make the whole system stable operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of existing gas turbine.
In accompanying drawing, 1 is turbine for turbine plenum, 6 for firing chamber, 5 for metallic conduit, 4 for the plenum of calming the anger, 3 for gas compressor, 2.
Embodiment
The utility model comprises gas compressor 1 and turbine 6, and the air outlet of gas compressor 1 is connected with two or more firing chambers 4 respectively; Institute's combuster 4 all is connected with the suction port of described turbine 6.
As a kind of preferred version of the present utility model, described gas compressor 1 place, air outlet is provided with the plenum 2 of calming the anger, and the suction port place of described turbine 6 is provided with turbine plenum 5.
As another kind of preferred version of the present utility model, between described gas compressor 1 air outlet and firing chamber 4, and all be connected by metallic conduit 3 between the suction port of firing chamber 4 and turbine 6.
Take two firing chambers 4 as example, using process of the present utility model is described: as shown in Figure 1, pressurized air enters by gas compressor 1 plenum 2 of calming the anger, and then mean allocation is two-part, enters respectively in two firing chambers 4; After the flow of gas flow rate and inflammable gas is divided into two-part, interior 1/2nd of former speed and the flow that all be reduced in firing chamber 4 separately, inflammable gas and air are after the two interior mixing in firing chamber 4, fully burning, enter again in turbine plenum 5, high-temperature gas flows to turbine 6 after the interior mixing of turbine plenum 5, voltage stabilizing, do work.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
