Technical Field

[0001] The invention relates to the technical field of yard gas monitoring, and in particular to an unattended gas sampling device for stone coal. Background Art

[0002] At present, in most thermal power plants, coal is generally used as the raw material for power generation. Before entering the boiler for combustion, the coal must be crushed by a coal mill to control the fineness of the coal powder entering the boiler within a relatively economical range to achieve the best combustion effect. The coal slag produced during the operation of the coal mill is pebble coal, which will accumulate in the yard. The pebble coal accumulated in the yard will volatilize sulfur and phosphorus, resulting in excessive concentrations of sulfur and phosphorus in the air. Therefore, it is necessary to design a yard gas sampling device to sample the gas in various parts of the yard. Summary of the invention
