Saturated or supersaturated flue gas moisture content measuring and calibrating device

Abstract

The invention discloses a saturated or supersaturated flue gas moisture content measuring and calibrating device, and belongs to the technical field of flue gas humidity measuring and calibrating. According to the invention, the problem that the device or the method for calibrating the saturated or supersaturated flue gas moisture content measuring device in the prior art cannot accurately calibrate the saturated or supersaturated flue gas moisture content is solved. The single gas electric heating device conveys heated single gas to the inlet end of the heat insulation flue through at least two single gas pipelines. The electric heating water vapor generator conveys heated water vapor to the inlet end of the heat insulation flue through at least two water vapor pipelines. The at least twosingle gas pipelines and the at least two water vapor pipelines are arranged in an up-and-down staggered manner, a gas thermometer and a gas pressure meter are arranged on an outlet pipeline of the single gas electric heating device, and a gas mass flow meter is arranged on each single gas pipeline; and a first water flow meter is arranged on an inlet pipeline of the electric heating water vaporgenerator.

Description

technical field [0001] The invention relates to a device for measuring and calibrating the moisture content of saturated or supersaturated flue gas, and belongs to the technical field of flue gas humidity measuring and calibrating. Background technique [0002] The measurement technology of saturated or supersaturated flue gas moisture content has made great technological progress in recent years, and some research results have been released or published one after another, such as published articles [Measurement method and influencing factor soft temperature and humidity of condensed flue gas based on in situ flue gasheat tracing ], patent [a condensing gas boiler low-temperature high-humidity exhaust gas temperature measurement and sampling device] and so on. These technologies or devices all require verification or calibration. At present, measurement units including the National Institute of Metrology cannot provide corresponding calibration platforms, which has led to di...
