description The utility model discloses an intelligent sensing accurate ammonia spraying system for a thermal power plant. The system comprises an ammonia gas input unit, a conveying unit, a control detection device and an ammonia spraying unit, the ammonia gas input unit comprises a vaporizer which vaporizes input liquefied ammonia into gaseous ammonia gas and conveys the gaseous ammonia gas to the ammonia gas conveying unit; the conveying unit comprises a booster pump and a flow regulating valve; the control detection device can detect the concentration of NOX in the desulfurization tower, calculate the amount of ammonia gas needing to be injected according to the detected concentration numerical value, and control the flow regulating valve to be opened to accurately inject the required amount of ammonia gas into the desulfurization tower, so that the denitration efficiency is improved, and meanwhile, the situation that emission does not reach the standard due to excessive injection of ammonia gas is avoided; and the a
