The chimney is a tube that allows smoke from combustion to be evacuated.
Chimney is the tube that allows the smoke derived from a combustion process to escape. This is a term that comes from the French cheminée .
Combustion
Combustion is the chemical reaction that occurs with the contact of an oxidizable material and oxygen . The fuel (that is, the oxidizable substance), in the presence of the oxidizer (oxygen), reacts quickly and heat is released.
The release of energy as heat and light usually includes flames. In addition, as a result of incomplete combustion of fuel, smoke is emitted (a gaseous mixture with solid particles in suspension). The chimney, in this framework, is the duct that channels the smoke and allows it to reach the outside .
Sometimes the idea of a chimney refers to some equipment or facilities that have this tube . Thus, a fireplace or a fireplace that is used for heating or cooking can be called a chimney.
ship chimney
A boat funnel, also known as the boat or ship funnel, is an essential structure that plays an important role in the operation and safety of the boat. Its main purpose is to facilitate the evacuation of exhaust gases produced by the engines.
Boat engines, whether diesel or otherwise, generate harmful exhaust gases that must be expelled to maintain a safe and efficient work environment for crew and passengers. The location and design of the funnel varies depending on the type and size of the boat.
In most cases, chimneys are located on top of the ship 's superstructure or deck, allowing exhaust gases to disperse into the open air without interference. Their design often includes an interior duct that directs gases from the engine to the opening at the top.
Boat chimneys are typically constructed of corrosion-resistant materials , such as stainless steel or marine alloys, to withstand harsh conditions, including exposure to salt water and humidity. This ensures that the structure is durable and reliable in the marine environment.
in geology
In geology , the term chimney is used to describe a geological feature that forms inside an igneous or plutonic rock called an intrusion . These are structures that originate as a result of cooling and crystallization processes of underground intrusive magma.
Chimneys form within igneous intrusions, which are masses of magma that solidify underground before reaching the surface. Minerals separate naturally due to differences in their density and chemical composition. This process is known as magmatic differentiation .
The boats also have chimneys to enhance the safety of the crew and passengers.
The composition of the chimneys is characterized by denser minerals (olivine and pyroene, among others) that accumulate in the center of an igneous intrusion as the magma cools and crystallizes. On the other hand, less dense minerals tend to form a matrix or halo around chimneys.
Chimneys typically have a cylindrical or tubular appearance within the igneous intrusion. As the surrounding rock cools and solidifies, the chimneys can retain their characteristic shape and structure, creating a type of tube or column within the intrusion. Their economic importance is considerable, as they are often associated with the concentration of valuable minerals.
firearms cannon
Certain firearms , finally, have a barrel known as a chimney in the chamber area. The capsule is located there so that, when the trigger is pulled, the charge receives the fire .
