The invention discloses a coal-fired power generation system and method. The system includes: an air separation device, a coking device, a combustion device, a first turbine and a first generator. The air separation device separates oxygen from the air, avoiding The nitrogen in the air participates in the combustion reaction, thereby reducing the emission of nitrogen oxides and ammonia, and reducing the emission of pollutants; coking the coal-fired raw materials through coking equipment, so that the hydrogen, sulfur and phosphorus in the coal-fired raw materials are polluted The waste is converted into gas, which further reduces the emission of pollutants and increases the output of gas; the charcoal generated by coking and the separated oxygen are combusted to generate high-temperature and high-pressure carbon dioxide, which is transported to the first turbine to expand and perform work. Drive the first generator to generate electricity, thereby improving the efficiency of electricity generation, and does not need to use gas to generate electricity, reducing energy consumption.
Description
technical field [0001] The invention relates to a coal-fired power generation system and method, and belongs to the technical field of energy saving. Background technique [0002] The characteristics of my country's energy structure determine the dominant position of thermal power generation in power production. In recent years, although the proportion of nuclear power, wind power, and solar power has been increasing, coal-fired power generation is still the absolute main force of my country's electricity production. As of the end of 2018, the national installed capacity was 1.90 billion kilowatts, and the installed capacity of thermal power reached 1.14 billion kilowatts, accounting for 60.2% of the total power generation in 2018. Because of this, in public opinion, coal-fired power plants have become the target of public criticism for causing air pollution and smog in our country. [0003] Relevant data show that my country's NO x and SO x The total emissions are about...
