The invention relates to a device and method for measuring 
ammonia escape content in 
flue gas and 
ammonia escape content in 
smoke dust simultaneously. At present, no device and method which are accurate in measurement and capable of measuring 
ammonia escape content in 
flue gas and ammonia escape content in 
smoke dust simultaneously exist. The device is characterized in that one end of an air guide 
pipe is connected with one end of a sampling 
pipe, the other end of an absorption liquid supply 
pipe is connected with the air guide pipe, one end of a first air guide 
branch pipe and one end of a second air guide 
branch pipe are both connected with the other end of the air guide pipe, the other end of the first air guide 
branch pipe is connected with a first condensation cylinder, the other end of the second air guide branch pipe is connected with a second condensation cylinder, and an analyzer and a flowmeter are both connected with a single-
chip microcomputer. The method comprises the steps that the first condensation cylinder and the second condensation cylinder conduct sampling alternately in sequence, the analyzer conducts analysis, the ammonia content in sampled 
flue gas is obtained, the flowmeter conducts measurement, the volume of the sampled 
flue gas is obtained, and thereby the ammonia escape concentration in the sampled 
flue gas is obtained. The device and method for measuring the ammonia escape content in the 
flue gas and the ammonia escape content in the 
smoke dust simultaneously are accurate in measurement, and the ammonia content in the flue gas and the ammonia escape content in the smoke dust can be measured simultaneously.
