The invention discloses a pulverized coal boiler biomass coupling power generation system with biomass and fire coal operating independently. The pulverized coal boiler biomass coupling power generation system comprises a biomass raw material bin, a star-shaped feeder, an air preheater, a steering chamber, a flue gas fan, a biomass fuel and conveying medium pre-mixing pipeline, a biomass fuel and conveying medium post-mixing pipeline, a branch pipe, a pulverized coal conveying pipeline, a coal mill, a hearth, a raw coal bin, a coal feeder, a cold primary fan, a coal mill inlet cold primary air pipeline, a coal mill inlet hot primary air pipeline and a coal mill inlet cold and hot air mixing rear pipeline. According to the system, the coupling proportion of biomass can be increased, the biomass system and the coal burning system can operate independently, and the flexibility of the system is high.
Description
technical field [0001] The invention belongs to the field of biomass coupled power generation in thermal power plants, and relates to a pulverized coal boiler biomass coupled power generation system in which biomass and coal are operated independently. Background technique [0002] According to my country's electric power development plan, by 2030, the total installed capacity of renewable wind power and solar power will reach more than 1.2 billion kilowatts. From the perspective of installed capacity, it will become the most important power source in my country. However, wind power and solar power also have shortcomings, that is, "uncontrollable", and the installed power generation capacity is severely limited by natural meteorological conditions such as day and night sunshine, seasonal changes, cloudy and sunny weather, and wind strength. According to reports, in 2019, when the proportion of non-fossil energy power generation in the country was only 32.6%, wind power and p...
