Abstract
The invention relates to a gas sampling device comprising a probe for sampling gas, an exploiting device for exploiting the gases sampled, a pipe for transmitting the gases sampled by the probe to the exploiting device, and means for lowering the pressure of the gases sampled in the pipe, to lower the dew point of the gases sampled, the means for lowering the pressure comprising an expansion nozzle arranged in the probe and communicating with the pipe, and a suction device for sucking the gases sampled in the pipe through the exploiting device. Application of the invention to the analysis of hot gases loaded with water vapor.
Claims15
A method of sampling gas comprising:
- sampling gas by a probe,
- transmitting the gases sampled by means of a pipe to a gas exploiting device using the sampled gases, and
- lowering the pressure of the gases sampled in the pipe and the exploiting device, to lower the dew point of the gases sampled therein to a value lower than the temperature of the pipe and the exploiting device, lowering the pressure of the gases sampled being performed by sampling the gases through an expansion nozzle arranged in the probe, and by sucking the gases sampled in the pipe exclusively through the exploiting device.
A device for sampling gas comprising:
- a probe for sampling gas,
- an exploiting device for exploiting the gases sampled,
- a pipe for transmitting the gases sampled by the probe to the exploiting device,
- an expansion nozzle arranged in the probe and communicating with the pipe, and
- a suction device for sucking the gases sampled in the pipe exclusively through the exploiting device, the expansion nozzle and the suction device being configured to lower the pressure of the gases sampled in the pipe, to lower the dew point of the gases sampled, below the temperature of the pipe and the exploiting device.
