History A smoke hood in the Netherlands Chimney pots in London, seen from the tower of Westminster Cathedral A seagull sits on top of a hot gas cooling chimney at The World of Glass in St. The dispersion of pollutants over a greater area can reduce their concentrations and facilitate compliance with regulatory limits.
Additionally, the dispersion of pollutants at higher altitudes can reduce their impact on the immediate surroundings. The height of a chimney influences its ability to transfer flue gases to the external environment via stack effect. The term smokestack (colloquially, stack) is also used when referring to locomotive chimneys or ship chimneys, and the term funnel can also be used. In the United States, the term smokestack industry refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. The space inside a chimney is called the flue. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect.

We recommend always replacing this type with a full custom chimney cap.Īlthough some Caps may be a round clamp style with a concrete crown or terra cotta (permanently affixed caps) these are rarer to find and install but we do repair and install these.This article needs additional citations for verification. They also provide a nice shelf for animals to build nests and due to their typical ill fit allow animals to enter through the gap in the pan and chimney stack or casing. They also do not fit well over the chimney casing and are often screwed in or caulked/glued on. They tend to leak around the seam where the flue meets the termination cap. This is the least expensive option and although does have some benefits it is not aesthetically pleasing as a full chimney cap.
The basic bottom pan with a termination cap is what we find on most chimneys from builder homes. Older Masonry Chimneys are more expensive to build and just not as common anymore in modern homes The metal flue is typically more of a modern style and used in homes 1980 and newer is usually just a bottom pan style with a round termination cap rather than a full custom top mount product.
