Chimneys operate based on the principle that hot air is less dense than cold air, and thus rises. When a chimney is filled with hot smoke or other gases, these gases rise up through the chimney. The hot, rising gas creates a pressure difference known as a draft which pulls combustion gases out of the building.
How Chimneys Work?
Chimneys are an essential part of many homes, but many people don’t understand how they actually work. Chimneys are designed to draw smoke and gases away from your home, and are made up of a number of different parts. In order to understand how chimneys work, it is important to understand what each part does.
The flue is the innermost part of the chimney, and it is the part that the smoke and gases travel through. It is typically made of clay tile, or stainless steel, and is lined with a material called refractory. This material helps to keep the heat of the smoke from damaging the flue. The flue also helps to draw air up through the chimney, pushing the smoke and gases out of the top.
The next part of the chimney is the smoke chamber. This is the part that is typically visible from the outside of the home. It is a large, hollow chamber that connects the flue to the outside of the home. It is usually insulated, and the walls are made of a material that is designed to reflect the heat of the smoke and gases away from the house.
The next part of the chimney is the chimney cap. This is a metal piece
