Description

Technical Field

[0001] The present invention belongs to the technical field of gas turbines, and in particular relates to a gas turbine co-combustion system coupled with solar ammonia and ammonia plasma and a use method thereof. Background Art

[0002] Heavy-duty gas turbines are the most efficient heat-to-power conversion power generation equipment to date. With the development of gas turbines, carbon emission reduction technologies are also gradually following up. Reducing carbon oxide emissions is a problem and challenge, so adding other zero-carbon combustible gases is one of the solutions. Ammonia, as a zero-carbon fuel, has significant advantages in calorific value, production, etc., so blending ammonia can reduce carbon oxide emissions. In the current relevant technical field, most of the ammonia is blended in boilers, and less in gas turbines.

[0003] Patent CN115234905B discloses a combustion system and method for producing hydrogen by decomposing ammonia and burning ammonia. Hydrogen is produced by using an ammonia decomposition and hydrogen purification device. Ammonia and hydrogen in different proportions are mixed as fuel. NH3 in the rich fuel mixture is used to generate NO x However, when this invention uses ammonia as the combustion gas, ammonia will still escape, resulting in the presence of NO in the exhaust gas. x , and the device is not coupled with other energy sources, resulting in high energy consumption.

[0004] However, there are still many problems with the current gas turbines that use ammonia: 1. Most of the current gas turbines that use ammonia are to directly gasify and burn liquid ammonia, or to crack liquid ammonia to produce hydrogen and nitrogen for combustion, and the utilization rate of ammonia is low; 2. Although using ammonia as a fuel reduces carbon oxides, it also increases NO x The emission of ammonia is also high, which will still cause pollution; 3. The exhaust gas produced after combustion is not used more efficiently; 4. Other energy sources are rarely combined with gas turbines to maximize the utilization of energy; 5. There are also few cases of co-combustion of co-combustion gas into plasma. Summary of the invention

[0005] The purpose of the present invention is to solve at least one of the above problems and provide a gas turbine co-combustion system coupled with solar ammonia and ammonia plasma and a method of use, so as to solve the problems of low ammonia utilization rate in the prior art and NO in the tail gas when ammonia is burned as fuel. x This solution maximizes the use of ammonia, uses solar energy to make ammonia participate in gas combustion in the form of gas and plasma, makes the gas turbine more efficient, and makes ammonia burn more stably and more efficiently. It also uses ammonia to treat the tail gas after work to reduce carbon oxides and NOx emissions, and when combined with solar energy, it can transmit electricity to the grid stably and continuously.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] One of the technical solutions of the present invention is to provide a gas turbine co-combustion system coupled with solar ammonia and ammonia plasma, including a gas turbine power generation component, a pyrolysis ammonia production component and a solar thermal power generation component;

[0008] The gas turbine power generation assembly comprises a compressor, a combustion chamber, a turbine and a generator a;

[0009] The pyrolysis ammonia production component includes a urea heat exchange pyrolyzer a, a urea heat exchange pyrolyzer b and a plasma generator;

[0010] The solar power generation assembly includes a solar collector, a steam turbine, a generator b and a storage battery which are electrically connected in sequence;

[0011] The output end of the compressor is connected to the input end of the combustion chamber to input compressed gas into the combustion chamber, and the combustion chamber also inputs natural gas. The output end of the combustion chamber is connected to the input end of the turbine. The compressor, turbine and generator a are connected through a shaft;

[0012] The urea heat exchange pyrolyzer a and the urea heat exchange pyrolyzer b are used to pyrolyze urea to obtain ammonia. The heat source of the urea heat exchange pyrolyzer a is the tail gas discharged from the combustion chamber, and the heat source of the urea heat exchange pyrolyzer b comes from the solar thermal power generation component. The ammonia is then input into the plasma generator and the combustion chamber respectively, and the output end of the plasma generator is connected to the input end of the combustion chamber;

[0013] The solar thermal power generation component is connected to the pyrolysis ammonia production component and is used for heat exchange and power supply for the pyrolysis ammonia production component.

[0014] Furthermore, compressed gas delivered by a compressor, ammonia delivered by an ammonia gas collecting box, and ammonia plasma delivered by a plasma generator are introduced into the combustion chamber, and then natural gas is introduced and mixed and burned in the combustion chamber. Using ammonia as a combustion gas can reduce the emission of carbon oxides. Adding ammonia plasma can more fully burn the ammonia generated by the thermal decomposition of urea. The ammonia and ammonia plasma themselves carry heat, which can also reduce the heat demand.

[0015] Furthermore, the blending ratio of natural gas, ammonia and ammonia plasma is (5-7):(3-2):(2-1), preferably (6):(2):(2).

[0016] Furthermore, the heat exchange between urea and tail gas in urea heat exchanger pyrolyzer a recovers the heat in the tail gas, while urea heat exchanger pyrolyzer b produces ammonia by utilizing solar energy to pyrolyze urea, thereby ensuring a stable and sufficient supply of ammonia.

[0017] Furthermore, the tail gas is introduced into the hot flow inlet of the urea heat exchange pyrolyzer a, and is discharged from the hot flow outlet after heat exchange with urea, and urea is introduced into the cold flow inlet, and ammonia after pyrolysis is discharged from the hot flow outlet.

[0018] Furthermore, the gas turbine co-firing system also includes an ammonia gas collecting box, which is respectively connected to the urea heat exchange pyrolyzer a, the urea heat exchange pyrolyzer b, the plasma generator and the combustion chamber. The ammonia obtained by pyrolyzing urea is first collected in the ammonia gas collecting box and then respectively input into the plasma generator and the combustion chamber.

[0019] Furthermore, part of the ammonia in the ammonia collecting box is output to the plasma generator, and the remaining part is output to the combustion chamber for direct combustion. The electric energy provided by the generator b causes the ammonia to react in the plasma generator to generate ammonia plasma, which is then output to the combustion chamber for combustion. The ammonia plasma can not only better carry out the combustion reaction, but also ignite the ammonia.

[0020] Furthermore, the gas turbine co-firing system further comprises a urea solution storage tank, which is respectively connected to the urea heat exchange pyrolyzer a and the urea heat exchange pyrolyzer b to provide urea.

[0021] Furthermore, the gas turbine co-firing system also includes a waste heat furnace, the input end of which is respectively connected to the hot flow output end and the cold flow output end of the urea heat exchange pyrolyzer a, and the tail gas is treated by SCR flue gas denitrification.

[0022] Furthermore, the urea heat exchange pyrolyzer a passes the tail gas into the waste heat furnace through the cold flow output end. In addition to passing a part of the ammonia generated by the pyrolysis of the urea heat exchange pyrolyzer a to the ammonia gas collecting box, the other part is passed to the waste heat furnace for ammonia spraying. The ammonia in the waste heat furnace passes through the ammonia spray grid to the SCR reaction module equipped with a catalyst to react with the tail gas and then discharged into the atmosphere.

[0023] Furthermore, the solar thermal power generation assembly is connected to a plasma generator, and the solar thermal power generation assembly supplies power to the plasma generator.

[0024] Furthermore, the solar collector outputs heat to the steam turbine; the steam turbine and the generator b convert the thermal energy into electrical energy; the generator b is electrically connected to the plasma generator, and the generator b provides electrical energy for the plasma generator and the storage battery.

[0025] Furthermore, the generator a and the storage battery are respectively connected to the power grid to supply power to the power grid, and the storage battery is used to provide electrical energy to the power grid when the power supply of the generator a does not reach the standard power supply.

[0026] Furthermore, the solar thermal power generation energy provided by solar energy can fully compensate for the power generation of the power grid from gas turbines. When the sunlight is insufficient, the production of ammonia generated by solar heat exchange will decrease, and the amount of ammonia burned will inevitably decrease. At this time, the storage battery can provide part of the electricity for the power grid to compensate for the energy conversion generated by the combustion of ammonia due to the lack of heat exchange.

[0027] Furthermore, the turbine is connected to the hot flow inlet of the urea heat exchanger pyrolyzer a through a high-temperature fan, so as to transport the tail gas to the urea heat exchanger pyrolyzer a.

[0028] The second technical solution of the present invention is to provide a method for using a gas turbine co-combustion system coupled with solar ammonia and ammonia plasma, specifically: the urea solution storage tank inputs urea into the urea heat exchange pyrolyzer a and the urea heat exchange pyrolyzer b, the heat source of the urea heat exchange pyrolyzer a comes from the exhaust gas of the combustion chamber, and the heat source of the urea heat exchange pyrolyzer b comes from the solar thermal power generation component. After urea heat exchange, ammonia is generated and output to the ammonia gas collecting box, and then output to the plasma generator and the combustion chamber respectively. The plasma generator generates ammonia plasma and inputs it into the combustion chamber. The ammonia plasma and ammonia are burned together with the compressed gas from the compressor and the natural gas in the combustion chamber, and drive the turbine and the generator a to generate electricity. The exhaust gas after work is passed into the urea heat exchange pyrolyzer a to recover heat, and finally discharged after being treated with part of the ammonia through the SCR denitration technology.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] 1. Since the propagation flame of ammonia is low, there may be incomplete combustion and ammonia escape. The arc generated by the plasma generator can ionize the ammonia. In addition to fully burning the ammonia plasma, the high-temperature jet characteristics can also be used to ignite the ammonia with a high ignition point, so that it can be fully burned in the combustion chamber, thereby improving the efficiency of the gas turbine. The utilization rate of ammonia is further improved by generating ammonia plasma;

[0031] 2. Air enters from the compressor and then passes to the combustion chamber. Natural gas directly passes to the combustion chamber. Part of the ammonia produced by pyrolysis is directly transported to the combustion chamber. The ammonia plasma produced after ammonia ionization is transported to the combustion chamber for combustion. The heat carried by the ammonia itself can increase the temperature of the combustion chamber and reduce the heat demand.

[0032] 3. The present invention uses ammonia to replace part of the natural gas combustion, and also allows the gas generated by the combustion of ammonia to be fully treated. The exhaust gas discharged after work is sprayed to the SCR reaction module equipped with a catalyst through the ammonia spray grid in the waste heat furnace, and reacts with NO in the exhaust gas under the action of the catalyst. x A reduction reaction occurs to generate nitrogen and water, and the exhaust gas is finally discharged with less carbon oxides and NO x Emissions meet environmental protection requirements;

[0033] 4. The heat sources of the urea heat exchanger pyrolyzer include the heat of the exhaust gas and solar energy. It recovers the heat in the exhaust gas and saves energy. It also makes the source of ammonia sufficient, ensuring the subsequent combustion of ammonia and the power generation of the gas turbine. In addition to being used for power generation, the exhaust gas of the gas turbine can also be used to achieve better thermal cycle efficiency of the gas turbine.

[0034] 5. The collector, steam turbine, and generator b generate electricity through solar thermal power. Generator a and storage batteries provide electrical energy for the plasma generator, ensuring the power generation of the gas turbine. The storage battery stores the electrical energy converted by the solar collector. On cloudy days, the heat energy converted by solar energy is relatively reduced, and the production of ammonia is reduced. At this time, the electrical energy converted by solar energy from thermal power generation can be compensated by the storage battery to meet the requirements of power transmission of the power grid. The power supply of the plasma generator can also be provided by the storage battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The combustion chamber 2 is introduced with compressed gas delivered by the compressor 1 , ammonia delivered by the ammonia gas collecting box 12 , and ammonia plasma delivered by the plasma generator 11 , and then natural gas is introduced and mixed and burned in the combustion chamber 2 .

[0047] The blending ratio of natural gas, ammonia and ammonia plasma is (5-7):(3-2):(2-1), preferably (6):(2):(2).

[0048] The heat exchange between urea and tail gas in urea heat exchanger pyrolyzer a 6 recovers the heat in the tail gas, while urea heat exchanger pyrolyzer b 7 produces ammonia by utilizing solar energy to pyrolyze urea, thus ensuring a stable and sufficient supply of ammonia.

[0049] The tail gas is introduced into the hot flow inlet of the urea heat exchange pyrolyzer a6, and is discharged from the hot flow outlet after heat exchange with urea. Urea is introduced into the cold flow inlet, and ammonia after pyrolysis is discharged from the hot flow outlet.

[0051] A portion of the ammonia in the ammonia collecting box 12 is output to the plasma generator 11, and the remaining portion is output to the combustion chamber 2 for direct combustion. The electric energy provided by the generator b 16 causes the ammonia to react in the plasma generator 11 to generate ammonia plasma, which is then output to the combustion chamber 2 for combustion.

[0052] The urea solution storage tank 8 is connected to the urea heat exchange pyrolyzer a 6 and the urea heat exchange pyrolyzer b 7 respectively to provide urea.
