What are the different types of steel chimneys?

Types of Steel Chimney Structure

• Self-supporting Steel Chimneys. When the lateral forces (wind or seismic forces) are transmitted to the foundation by the cantilever action of the chimney, then the chimney is known as self-supporting chimney.
• Guyed Steel Chimneys.

What is a Type 1 chimney?

A Class 1 chimney is common in houses built up until the 1960s. They consist of a brick-built stack, situated on either an internal or external wall and containing multiple flues for multiple fires (although the fires cannot share a flue).

What is the difference between a chimney and a flue?

A flue is the channel, pipe, or tube through which gases and smoke travel from a source of combustion (fireplace, furnace, boiler) to the outside environment. A chimney is, on the other hand, in its simplest definition, the housing that encases the flue. It is usually made of masonry, brick, or stone.

What kind of chimney is good?

A kitchen chimney with higher air suction capacity is ideal for Indian kitchens. For frequent cooking, the range should be between 400 m3/hr to 1000m3/hr, depending on the size of your kitchen. The chimneys with a long hose have generally more suction power.

What is a Type 2 chimney?

Prefabricated Flues (Class 2) They are made up of interlocking metal flue pipes. You can easily identify a prefabricated flue by the metal cowl on the roof, which looks like a thin metal chimney.

What is a Class 2 chimney?

Class 2 flue. A conventional flue but is only 5 inches in diameter. The range of gas fires that can be fitted to a class 2 flue is slightly reduced to that of a Class 1 flue. Pre-cast flue. Usually found in more recently built properties.

What is a Class 1 or 2 chimney?

You can have electric, gas and gel fires with a prefabricated flue. They’re not equipped to deal with solid fuel fires. Essentially, if your flue diameter is 7 inches, you’ll need a class 1 fire. For 5 inch flues, you’ll need a class 2 fire.

How many types of chimneys are there?

3 Types of Chimneys: Factory-Built / Prefabricated. Masonry Brick or Stone. Freestanding Stoves.

What is gas chimney?

1. n. [Geophysics] A subsurface leakage of gas from a poorly sealed hydrocarbon accumulation. The gas can cause overlying rocks to have a low velocity. Gas chimneys are visible in seismic data as areas of poor data quality or push-downs.
