Chimney functions.
The most important function of the chimney, of course, is the creation of a traction of such a force that can, by means of ordinary physical laws, remove all impurities from the building to the environment. The physical process that occurs inside the chimney can be easily explained. Due to the large difference in pressure in the boiler itself (system) and directly in the head of the pipe, all polluted air goes into the environment. If, part of the chimney system is located on the street, then, of course, it should be thoroughly insulated quite thoroughly.
