Funny forwards are a method of passing on emails to someone who did not receive the original email. This may be a work colleague or friend that does not have contact with the original sender. The following was forwarded to me earlier today:
The fireplace is feature within a building that is intended to contain fire for heating and occasionally for cooking. They can house electric fires, fuel fires or some other source of heating. The fire itself is usually contained within a firebox or a small pit, and a chimney or similar system is used to allow the exhaust to escape. Historically fireplaces are a central feature within the house, although this is now less common.
The fires themselves can be powered in a myriad of ways. Wood fires are the most ancient of heating sources. When available, peat was often used instead of wood as it lasted much longer and burnt more efficiently. Coal and peat fires became more popular during the industrial revolution. Electric fires followed with the development of electricity and became popular in the middle of the twentieth century. In recent years, propane and bio-fuels are becoming more widely used.
Some older fireplaces have been kept as design features within a building. These may not have the original heating system within them, but are left to enhance the ambiance of the room. Some of the heating systems may have been replaced with modern equivalents. Electric heaters may have been introduced to provide heat without the fire. Some are left empty and used for purely decorative reasons.
A fireplace may use some or all of these components: a hearth, a foundation, a fireplace mantel, a chimney crane, a cap, a smoke chamber, a firebox, an ash-dump door, a lintel, a chimney breast, a cleanout door, over-mantel, a throat, a flue, a damper, a chimney chase, a spark arrestor, a crown, or a shroud.
There are several types of fireplace. Masonry fireplaces are constructed from brick or stone. Some are made from reinforced concrete, but these are fundamentally flawed as the concrete and metal expand at different rates. This means that many old fireplaces have vertical cracks leading up the chimney.
A manufactured fireplace uses a prefabricated design, so are extremely popular with newer builds. They usually consist of one metal firebox connected to a long metal pipe, effectively a chimney that vents the exhaust. As it has a metal structure it is susceptible to sparking, and so spark arresters are usually installed. Natural gas, propane and wood are the standard fuel sources for this system.
Duct Free fireplaces are fueled by gel, LP/bottled gas or natural gas. They are quite easy to install and do not use the same BTUs as other fireplaces. Many states and countries have special regulations regarding these fireplaces. Some of the fireplaces can burn to almost one hundred percent efficiency. However, they have been known to release a large amount of moisture into the surrounding air.
A bio-ethanol fireplace is sometimes referred to as a flue-less fire. This is because it does not need any kind of exhaust ventilation. They are therefore 100% efficient because at keeping all the heat in the room. They are more often than not powered by bio-fuel and unlike some other fireplaces there is no soot whatsoever produced by these fires. It only produces water and low amounts of carbon monoxide and carbon dioxide.
