Description

technical field

[0001] The invention belongs to the technical field of sampling high-temperature, dust-laden and corrosive gases, and relates to an automatic sampling device and a sampling method for high-temperature, high-pressure dust-laden gas, in particular to an automatic sampling device and method for industrial furnaces for high-temperature, high-pressure dust-laden gas. Background technique

[0002] In the field of high-temperature and high-pressure dust-laden gas sampling technology, it has been difficult to achieve stable and rapid sampling. Generally, the sampling device is easy to block and has a short life; . For example, in the field of circulating fluidized bed gasification technology, the crude gas temperature is above 900°C, and the crude gas contains solid particles such as coal ash and quartz sand, and the H in the crude gas 2 S, SO 2 etc. are toxic and corrosive. Once the device is blocked during sampling, it will not only increase the work intensity of...
