The chimney

The chimney is that element of construction that serves the conveying of fumes from a burning from within a room or the combustion chamber to the outside.

Traditionally it is made of brick or stone associated with malta.o of metal pipes of various kinds, mostly in stainless steel (single wall pipe, double wall, flexible single wall with smooth interior).

technical divides what is generally called chimney into three parts:

• Smokingchannel (or conduit connecting element between the generator of heat and chimney for the evacuation of combustion products such as tubes on a wood stove)
• flue or chimney (the vertical part)
• chimney (this is the end of the chimney to the sky).

Channel smoking

The technical standards (UNI 10683), under the definition of the components of the exhaust fumes produced by a burner, sets the channel to be smoke conduit or connecting element between the generator and heat chimney. It is usually made of metal (steel or painted steel, cast iron, etc.).

chimney

The chimney is the last part of the chimney, most often referred to as chimney. Assumes different forms according to local traditions or architectural styles.

Features and operation

The chimneys can be built up (eg bricks during construction of the roof) or precast (mostly in brick or metal)

The function is to disperse in the smoke and other combustion products. It must also prevent the penetration of foreign bodies (rain, snow, birds or more) for this reason the majority of chimneys has coverage fenestro to let out the smoke, but as to protect this.

The operating principle is very simple: in the absence of air currents external smoking quit anyway being lighter than air. In the presence of wind efficiency increases as the chimney takes advantage of the Bernoulli principle: that if a current of air passes over the opening of the chimney, it creates a sort of aspiring suck the smoke from the barrel by increasing the speed of exit. Is thus increased draft.
