2021-10-09

The invention discloses an on-line water dew point and acid dew point measuring device for flue gas introduction method, which relates to the field of flue gas detection, including a computer control system and a flue gas thermostat. The flue gas thermostat is connected with a flue gas buffer, a liquid discharge port is arranged at the bottom of the flue gas buffer, one side of the flue gas buffer is connected with a horizontally arranged test pipe, and the end of the test pipe is connected with a flue gas buffer tank, The bottom of the flue gas buffer tank is connected with a flue gas discharge device; A test pipe is arranged in the test pipe, one end of the test pipe is connected with a warm water circulation pipeline after passing through the flue gas buffer, and the other end is connected with an adjustable warm water device after passing through the flue gas buffer tank; Thermal resistance, capacitance sensor and dew point probe connected with computer control system are installed on the test tube.  The invention obtains a real acid dew point control point through the correction of the mathematical model of the acid dew point, which is used as an optimized flue gas emission temperature control point of the furnace to improve the thermal efficiency of the furnace.
