Abstract

The invention discloses a system enabling boiler oxygen-rich combustion to be combined with an electrolytic hydrogen production peak and frequency regulation apparatus. The system comprises a power plant centralized control peak and frequency regulation control module, a boiler oxygen-rich combustion module, and an electrolytic hydrogen production peak and frequency regulation apparatus. The system improves the load reducing capability of a boiler itself and also enables a set to carry out in-depth peak and frequency regulation operations anytime during four seasons, so the flexibility of thethermal power set can be greatly improved. The system is widely applied to combined heat and power sets or pure condensing set. Moreover, environment pollution is low since clean fuels are provided bya power plant, power plant resources are utilized effectively, and the economical efficiency of the power plant is improved.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a system and a method for boiler oxygen-enriched combustion combined with electrolytic hydrogen production peak-shaving and frequency-regulating equipment. Background technique [0002] In China's three northern regions, the power market capacity is abundant, gas turbines, pumped storage and other peak-adjustable and frequency-regulated power sources are scarce, and the contradiction between power grid peak-adjustment and frequency modulation and the flexibility of thermal power units is prominent. The energy capacity is insufficient, and the phenomenon of abandoning wind, light, water and nuclear is serious. [0003] In the prior art, cogeneration units include boilers, steam turbines, generators, condensers, deaerators, and power grids. They operate in the mode of "heat-constant electricity". In winter, due to thermoelectric coupling, the peak-shaving and frequ...
