Discussion on the Whole Process Low-Carbon Energy Saving Technology Path of Coal-Fired Power Plants

[Introduction] Low carbon emission technology of coal-fired power plant is an important strategy to alleviate energy crisis and environmental pollution in China. [Method] The low-carbon emission reduction path and potential development direction of low-carbon technology in fuel supply design stage and energy-saving operation and maintenance stage of current coal-fired power plants were reviewed. [Result] For the low-carbon technology in the design stage of power plant fuel supply, the ratio of biomass/ammonia and coal mixing should be optimized. A good ratio of biomass/ammonia mixing and burning should be fully burned in the furnace to reduce carbon emissions. Absorption technology, adsorption technology, and gas separation technology are common means of carbon particle capture in the energy-saving operation and maintenance stage of the power plant. At the same time, the important role of energy storage technology, deep peak regulating technology, and flexible DC power supply technology on the CO2 emission reduction path is expounded. [Conclusion] Finally, the development of low carbon technology in power plants is prospected. It is considered that the adoption of a comprehensive complementary and low carbon collaborative way, combined with the regulatory feedback control measures in the operation process of power plants. It will be an important development direction to promote the sustainable energy development of power plants.
