The invention relates to the technical field of denitration, and particularly discloses a method for improving SNCR (selective non-catalytic reduction) denitration efficiency. The method for improving the SNCR denitration efficiency comprises the following steps: S1, heating an amino reducing agent to 60-90 DEG C for atomization; s2, when the temperature of the flue gas is 850-1100 DEG C, the flue gas is introduced into a denitration reactor, the atomized amino reducing agent is sprayed into the denitration reactor, and meanwhile a magnesium tetraborate solution is sprayed into the denitration reactor after being pressurized and atomized. The method for improving the SNCR denitration efficiency has the advantage of improving the SNCR denitration efficiency. 本申请涉及脱硝技术领域，具体公开了一种提高SNCR脱硝效率的方法。一种提高SNCR脱硝效率的方法为：S1、将氨基还原剂加热至60-90℃雾化；S2、烟气温度为850-1100℃时通入脱硝反应器，将雾化后的氨基还原剂喷入脱硝反应器中，同时将四硼酸镁溶液增压雾化后喷入脱硝反应器内。本申请的提高SNCR脱硝效率的方法具有提高SNCR脱硝效率的优点。
