Description
Technical Field
The invention belongs to the technical field of coal-fired power generation, and particularly relates to a system and a method for reducing carbon dioxide emission of a coal-fired unit by using ammonia combustion.
Background
There are no more than two ways to reduce or reduce carbon dioxide for a coal burning unit: one is to capture carbon dioxide at the tail of a boiler, also called as CCUS, but although the technology is developed for many years, the capture cost is far beyond the range which can be borne by a thermal power generating unit, and the application of the technology is seriously influenced; the other is that the inlet end of the boiler is partially or completely combusted by carbon-free fuel, such as biomass, but the biomass is regional and seasonal, has higher cost and is not suitable for a coal-fired unit with high requirement on stable supply.
Both coal and natural gas produce a large amount of carbon dioxide during combustion, and domestic and foreign scholars propose a lot of alternative fuels, wherein hydrogen is favored by people due to the characteristics of no carbon emission, wide combustion limit and the like. However, hydrogen is extremely low in energy per volume when transported relative to conventional fuels, and is 4 times less than gasoline when stored in liquid form at-235 ℃. In addition, hydrogen has a complex safety problem in storage, transportation and use due to its low ignition energy and high flame propagation speed. Ammonia is also considered a promising clean energy carrier and storage medium. Similar to hydrogen, ammonia may be obtained from fossil fuels, biomass, or other renewable resources. Compared with hydrogen, the cost of unit stored energy of ammonia is lower, the volume energy density is higher, and the method is safer and more reliable.
TABLE 1 NH3And H2、CH4Physical and chemical properties
NH3、H2And CH4The physicochemical properties of typical fuels are shown in table 1. It can be seen that H2Liquefaction at ambient temperature (25 ℃ C.) requires 70MPa, while NH3Liquefaction at normal temperature only requires 1.03MPa, which makes H2The cost of compression, storage and transportation is far higher than that of NH3(ii) a H carried in unit2Mass calculation, NH3The half-year hydrogen storage cost is only 0.54$/kg H2And H is2The half-year hydrogen storage cost is as high as 14.95$/kg H2. Overall, the advantages of ammonia as a fuel can be summarized as:
(1) belongs to carbon-free fuel, has no greenhouse gas emission, and can be synthesized by a carbon-free method through renewable energy sources;
(2) the energy density is 18.8MJ/kg, and is equivalent to fossil fuel (the heat value of low-rank coal is about 16-20 MJ/kg, the heat value of natural gas is about 50MJ/kg, H2Calorific value 141 MJ/kg);
(3) the liquefaction pressure is only 1.03MPa, and the liquefaction is easy;
(4) about 1.8 million tons of NH per year3Is produced and transported, and therefore has a mature and reliable infrastructure for NH3Storage and transportation (including pipeline, road, rail anda ship).
Table 2 compares the total cost per calorific value of liquid ammonia and Liquefied Natural Gas (LNG) by calculating the mass calorific value of the fuel, the production cost, the transportation cost, and the carbon emission reduction profit. As can be seen from the table, when only the preparation cost is calculated, the total cost of the unit heat value of the liquefied natural gas is about 83.6 yuan/GJ, and the total cost of the unit heat value of the liquid ammonia is only 74.4 yuan/GJ, and from the comparison of the data set, when any transportation cost and carbon emission reduction benefit are not calculated, the price of the liquid ammonia as fuel is the lowest, and the cost of the unit heat value of the liquid ammonia of 1400 yuan/t is converted into the cost of the unit heat value of the gaseous natural gas of 2.67 yuan/m3Much lower than 3 yuan/m3. The liquid ammonia can also be transported by utilizing the existing natural gas pipeline, and the transportation cost is equivalent to that of LNG. With the counting of carbon emission reduction benefits, the use price of liquid ammonia is further reduced.
TABLE 2 cost calculation for liquid ammonia and Liquefied Natural Gas (LNG)
Note: (1) price of liquefied natural gas in table is 3 yuan/m of industrial gaseous natural gas3Calculating to obtain;
(2) carbon emission reduction benefit: the carbon value of the european union in 7 months in 2019 was 28 euro/ton.
In addition, ammonia gas can be prepared by coal, and can also be prepared by using electricity waste or trough electricity generated by part of renewable energy sources, and the electricity waste or trough electricity can be used for power generation or heat supply when the electricity is insufficient; synthesis of NH by electrochemical process instead of coal gasification and natural gas reforming3And also can realize NH3Zero carbon emissions over the full life cycle.
