Abstract

The exhaust system for expelling gases (2) from the chimney (1) belongs to the field of effect use on the jets that emerge from an opening, on the flow of fluids in pipes or conduits and the effect on the boundary layer. The device consists of a pipe (7) which supplies air under pressure and enters the joint of a pipes (8) located in the middle of the circular pipe. The pipe (8) enters a pipe (3). To the pipe (3) are welded pipes (4) and (5). Between the pipes (4) and (5) flows pressurized air and moves to the internal pipe of the chimney (1). The flow of the air under pressure coming out of the chimney (1) prevents the turbulence of the outgoing gases (2) on the boundary layer and its expansion and creates an air tube through which the gases (2) move without friction. In this way, the height of the real air column of gases (2) increases considerably. This avoids increasing the height of the chimney (1), in order to expel the gases (2) to a greater height and thereby prevent environmental pollution of the area around the chimney (1).
