Chimney Flue System for Home
Chimney is the device which helps in ejection of smoke, flue gas from an enclosed area to the outside atmosphere. It consists of a vent and the space provided inside is called as the flue. Chimneys are used in households, industries, ships. The vents are kept at a higher place so that the smoke coming does not pollute the surroundings which are close by. Chimneys are built in stacks along the walls and have a common vent in household. These are placed internally. Depending on the usage the flue system varies.
The chimney consists of cowl, top and chimney pots. Chimney pots determine the design or draft of the chimney. Chimney cowl is build at the top in order to prevent birds to build nests. They also act as a rain guard to prevent rain water entering inside the chimney. If you have an open fire top then during heavy winds the smoke vented out get reversed causing smoke to be filled in the room. These also have a metal wire which acts as a spark plug when excessive smoke goes out. The cowls have come in different styles they are wind directional cowl, oak cowl, H shaped cowl, wind rolling cowl, boat's ventilator cowl. Out of these the most significant one is the H shaped cowl.
Chimney flues determine the capacity of the fire to be burned. These are the space provided inside the chimney for the amount of smoke burnt out and also the capacity. Selection of the flue system is the most important part of the chimney structure. These are of various types and depend on the material used. They may be thin walled or thick walled. Thin walled flues are mostly used in households are basic, traditional ones. These are built up using bricks. Whereas the chimney in a boiler plant industry is built externally and placed near a boiler unit. Here it is made up of refractory bricks. Some do have multiple vents within them made up with concrete.
Chimney linings should be done as it plays a vital part in the parameters of the chimney. Smooth lining makes tar not to be accumulated easily, provide proper vent for the flue gases to escape easily. Proper venting prevents smoke or dust to escape through cracks. The flue pipe lining are of two types Class I and Class II. Class Imade up of bricks they can also consist of metal, some ceramic coatings these use traditional coal, wood or fuel for burning.
Class II linings are less strong compared to that of class I and mostly made of aluminum. These are suited for small gas fires. Class II linings are found in flue systems found in block system in buildings and this is noticed by the presence of the edge ridge tiles. Class I lining can be made to Class II with the help of lining. Stove pipe linings need not depend upon only on the fireplace, like that of the earlier days and now have come with various advancements. With the introduction of class II linings, the linings for stove pipe have become easier. Class II linings have come in different style Flue less, balanced flue and Power flue.
However the use of chimneys have brought to a great use these as it provides as an gas exhaust region. The drawback in the chimney pipes and linings are the accumulation of dust and tar and thus needs proper maintenance
