Three Chimneys
Contest Directions: This Friday we continue our freaking experiment with provided source images.
Photoshop this image of three chimneys (image credit: echiner1) any way you wish. Some examples are - re-shaping these chimneys, decorating the chimneys, merging them with some other objects, using this chimneys image in movies, paintings, etc. These are just some ideas.

This contest is fueled by the following news: A chimney is a pipe for venting out furnace gases or fireplace smoke into the atmosphere. Usually, a chimney is a vertical pipe but can consist of individual horizontal or inclined sections. History: For the first time a chimney was described by Greek Theophrastus in the 4th century BC. In the ancient world, pipes were used in the walls of the buildings for venting out the gases from bakeries, however, modern-day pipes appeared only in Europe in the 12th century. Industrial chimneys appeared in the end of the18th century. The invention of chimneys is inseparably associated with heating facilities. The simplest of them all a bonfire, surrounded by stones. In ancient times, such a heating "design" allowed to warm oneself near the fire and prepare simple food but not more than that. The issue of how to store the heat for a reserve of several days started playing on the minds of people much later, when they started moving further towards the north. For instance, in the Ussuri zone, according to the evidence of V.K. Arseniev, a traveler and writer, who studied that region, the houses of settlers from Korea were warmed by very interesting chimneys, which ran in the house floor and passed through the habitable zones, thus warming them. The combustion products exited outside through a hollow tree, which was used as a replacement to the external portion of the chimney by them. Functionality of chimneys: The main function of chimneys is the withdrawal of gases (fuel combustion products in a fire box). The following are discharged along with combustion gases: smoke, soot, ash and smoke-black, which, if the inner surfaces of chimney are not made properly, can settle down on its walls, thus making it difficult for further passage of gases. So as to eliminate this, it is necessary to make the inner surface of chimneys as even and smooth as possible without potholes, slots and ledges so that the soot and smoke-black should not have anything to hold on to. But, it is not allowed to smooth out the inner portion of the chimney with clay since it is a bad heat conductor and can lead to the occurrence of condensate and the dampening of the tube, eventually leading to poor air circulation (traction). One more function of chimneys is to provide a normal draughting furnace, which is a direct ratio with the thickness and height of the chimney channel. The temperature of combustion products at the outlet of the tube can exceed 373K , which promotes the creation of a natural draught in the heating facility - by replacing the hot air layers with cool air layers. Due to this, the wall thickness of a chimney flue should not be less than one and a half bricks (the ideal ratio for native type flues) and a height of 5 meters and more starting from the grate area. Design features of chimneys: The majority of brick designs were forced to be vertical. Due to the emergence of new materials, the vertical design ceased to be a strict requirement. Most often, chimneys are made of bricks. Standard masonry chimney consists of the following elements (the description is given from a top to bottom sequence): * Metallic crown; * Cap; * Lintel; * Concrete slope; * Ceiling rafters; * Footing; * Furring; * Chimney stacks * insulation layer near ceiling and beams; * Chimney damper. More often, prefabricated insulated metallic flues are used as a replacement to brick flues. It is necessary to assemble them using typical factory-production elements, which are to be fixed after every 150 cm to the walls or other structures since they are not self-supporting designs. Predominantly, such flues are manufactured from aluminum (upper portion) and acid-resistant stainless steel (inner portion). The space between them is filled with a special heat insulating material. Structurally, a heat insulated roof-type steel chimney consists of the following components (description is given from top to bottom): * Cowl; * End element; * Intermediate element; * Intermediate element with cleaning channel; * mounting frame (base chimney, starting with the attic floor); * Cross section of heat insulating pipe; * Intermediate element with adapter; * lower element with cleaning channel pipes, starting with the floor. Industrial production in some countries also offers for sale tall chimneys (up to the floor), which are based on lightweight concrete. Structurally, high concrete chimneys consist of: * Brickwork (120 mm); * Joint (10 mm); * Heat insulation plaster layer (30 mm); * Hearth stone; * Various elements (connecting, intermediate, bottom and top); * Ash dump hatch. Chimney cap: This serves many purposes: protection from snow and rain, increase in traction, decoration of roof. Basic problems: There are two of them - deposits on the inner walls, which reduce the cross section of the flue and damage of the flue from inside and outside under the impact of corrosive combustion gases and wind loads.
