Abstract
The invention discloses a process and a system for combining waste electricity hydrogen production with circulating fluidized bed boiler combustion. During deep peak regulation, a part of flue gas is used as circulating flue gas, a part of circulating flue gas is mixed with air or oxygen to obtain primary air, the primary air is used as fluidizing air to enter a hearth from the lower part of the hearth, the other part of circulating flue gas is mixed with oxygen to obtain secondary air, and the secondary air is fed into the hearth from the upper part of the hearth; the oxygen content in the primary air is lower than that in the air, and the oxygen content in the secondary air is higher than that in the air; the oxygen for mixing comes from a water electrolysis hydrogen production process; and in the water electrolysis hydrogen production process, waste electricity is adopted for water electrolysis hydrogen production. By means of the process and system, the problems that in-furnace fluidization safety is poor when the circulating fluidized bed unit is subjected to deep peak regulation, the original generation amount of in-furnace nitric oxide is increased, and the concentration of carbon dioxide in flue gas is low can be effectively solved, and therefore the deep peak regulation capacity of the circulating fluidized bed boiler generator unit is improved.
