摘　　要：煤电机组基于现有相关技术体系,可以通过“三步走”减碳战略,即通过技术减碳(节能降耗和深度调峰)实现低碳化,通过燃料脱碳实现零碳化,通过烟气脱碳实现负碳化,逐步实现转型,成为具备煤电机组可靠、可调和稳定等所有优点,同时又解决其高碳排放这一痛点的优质新能源火电。生物质火电作为一种零碳新能源,可以同时破解“风光新能源加电储能无法真正保障电网安全”和“传统煤电稳定可调但碳排放强度过高”这2个困局,成为我国未来低碳电力供应的中坚力量,为尽早实现以新能源为主体的新型电力系统作出其历史性贡献。Based on the existing relevant technical system,coal-fired power units can be gradually transformed through the“three-step”carbon reduction strategy,that is,through technical carbon reduction(coal consumption reduction and deep peak shaving)to achieve low carbonization,through fuel decarburization to achieve zero carbonization,through flue gas decarburization to achieve negative carbonization.The strategy makes coal-fired power units have advantages of reliable,harmonic and stable,and solves the high carbon emissions of the units.As a kind of zero-carbon new energy,biomass thermal power can simultaneously solve the following two dilemmas:the wind and solar new energy power plus energy storage can’t really ensure the safety of power grid;the traditional coal power is stable and adjustable,but the carbon emission intensity is too high.Biomass thermal power has become the backbone of China’s future low-carbon power supply,and will make historical contributions to the early realization of a new power system with new energy as the main body.
