中国"煤电+氨"产业布局与经济效益分析OA

Ammonia-coal co-firing,as an emerging technology applicable to coal-fired power plants for effectively reducing CO2 emissions,has received widespread attention.Recent extensive researches have primarily focused on the performance of ammonia-coal co-firing,pollutant emissions,and its impact on unit efficiency,while studies on the industrial layout and economic feasibility of ammonia-coal co-firing remain insufficient.According to literature reviews,most green ammonia synthesis processes via water electrolysis for hydrogen production in China are distributed in the northwest regions such as Inner Mongolia.Considering ammonia transportation costs,ammonia-coal co-firing holds significant promotion advantages in northwest China.Furthermore,taking a 330 MW pulverized coal boiler in a power station as an example,the economic feasibility of coal-ammonia co-firing was evaluated.Results indicate that the operating costs of ammonia-coal co-firing units are significantly influenced by ammonia costs,carbon prices,and co-firing ratios.When the price of green ammonia drops to 1 600 CNY/t and the carbon price rises to 551.34 CNY/t,the economics of a unit with 15%ammonia co-firing become comparable to that of a coal-fired unit.Increasing the co-firing ratio proportionally raises the total operating cost of ammonia-coal co-firing units and affects the sensitivity coefficients of other factors,making high co-firing ratio scenarios more likely to achieve cost parity with coal-fired units.These findings could provide valuable insights for promoting ammonia-coal co-firing technologies.
