What is the white smoke from the factory chimney?
But also can prove that the enterprise is using environmental protection equipment. In order to meet the emission standards and reduce dust pollution, enterprises will install water filtration equipment at the equipment discharge terminal, and the waste gas discharged from boilers will enter the water filtration to filter out the dust inside and then be discharged into the atmosphere. While filtering dust, the high heat in the waste gas is also absorbed by water, forming water vapor to be discharged from the chimney. When it is cold, it is white smoke that we see. This can also explain from the side that the pollutants discharged by boilers meet the national emission standards.
Extended data:
1, black smoke
Careful friends should find that there are fewer and fewer big chimneys smoking black smoke now, but there are still many chimneys smoking black smoke in some small enterprises and workshops. Most of these small enterprises burn the cheapest and worst quality loose coal, and the waste gas generated by combustion is directly discharged without treatment. Loose coal contains a lot of sulfur and nitrate components, and the sulfur dioxide and nitrogen oxides produced after combustion are extremely harmful to human body, so the pollution is also the biggest.
2. Yellow smoke
If the smoke column discharged from the chimney is yellow, it means that the flue gas contains a lot of sulfide, which means that the desulfurization equipment of the boiler has not been put into use.
