The invention belongs to the technical field of pollutant control, and particularly relates to an ammonia production device and method for a thermal power plant. The invention provides an ammonia production device and method for a thermal power plant. The ammonia preparation device of the thermal power plant comprises a urea feeding pump, a bypass pneumatic valve, a pneumatic control valve, an Al2O3-MnO2 catalytic hydrolysis device, a urease catalytic hydrolysis device and a mechanical compressor. Wherein in the rapid load increasing stage of the thermal power plant, the amount of generated nitrogen oxide NOx is large, the demand quantity of ammonia gas is large, the hydrolysis rate of the urease catalytic hydrolysis device for hydrolyzing urea can reach 1000 times or above of the hydrolysis rate of common catalytic urea, and therefore the demand quantity of ammonia gas in the rapid load increasing stage can be met; according to the ammonia production device for the thermal power plant, the technical problems
