Chimney
The road for gas carrying the chimney flue and exhaust air handling path for stack ventilation. Commonly it is a vertical design for construction.
Breakdown by function
* Smoke - the flue gas (gas containing oxides beyond the dust and soot and water vapor) from the solid fuel-fired furnaces
* Combustion - are used to the furnace flue gas and liquid fuel fired
* Ventilation chimneys:
* Supply, which are used to provide the necessary air in the combustion process
* Hoods used to exchange air in the room
Breakdown due to construction of housing
* Single-layer stacks - the wall is homogeneous conductor, such as brick chimneys, thick steel, cement, clay, etc.
* Multi-layer stacks - the chimney wall is composed of several layers
Breakdown by location
* Internal - Flues various purposes grouped into stacks,
conducted inside the building as an independent non-building construction, or associated with the wall and carried on as a supporting wall chimney
* External - conducted chimney outside the building may be structurally related to the building, or a particular kind of chimney unrelated to the building - detached
Division due to the nature of the work
* In the wet mode - from low-temperature, gas central heating boilers, boiler
condensation, where the temperature of the exhaust gas is contained in the range of 80 ° C -160 ° C,
* In a dry mode - a stack of solid fuel furnaces where flue gas temperature
higher than 160 ° C.
* Working in hypertension - when the pressure inside the chimney is higher than the pressure
external (atmospheric)
* Working in a vacuum - when the pressure inside the chimney is lower than
atmospheric (string gravity)
Division in relation to a string
* Chimneys of the natural
* Chimneys of the artificial:
* With fan herbinger
* With extractor fan,
* Mixed system
The types of chimneys
* Free-standing - mostly built of prefabricated fittings such as concrete or steel
* Built-in - stacks inside buildings, they are made of full ceramic bricks or fireclay (formerly) or stainless steel (now).
