The invention provides a method for evaluating influences of a denitration system on coal consumption of a coal-fired unit. The method includes the steps that S1, flue gas flow of an inlet section and outlet section (1, 2) of the denitration system is measured; S2, the flue gas temperature of the sections (1, 2) and the environmental temperature (Ta) are measured; S3, power consumption Wxs of a dilution fan is measured; S4, system air leakage delta Q (delta Q = Q2-Q1) is calculated out; S5, flue gas enthalpy value of the sections (1, 2) is calculated, and delta H and air enthalpy value Ha are calculated; S6, the changed value caused by the denitration system to input energy of an original thermal system is Q1*delta H+delta Q*(H2-Ha)+Wxs; numerical units are unified to obtain the influencing numerical value of the denitration system on the coal consumption of the coal-fired unit. The method is simple, and easy to operate, and provides more accurate power supply coal consumption calculation of the coal-fired unit; the denitration system has been widely installed in coal-fired power plants, the defect that influences of a new denitration environmental protection device on machine unit energy consumption are not considered in a traditional calculating method is overcome, and disputes caused by less rigorous calculation in the process of acceptance check of devices can also be reduced.
