Question: Provide another name for a structure that provides ventilation for hot flue gases, or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere, used in relation to boats rather than buildings, an example being the paddlewheel steamboat known as the Lexington which sank due to an onboard fire when the structure caught fire igniting 150 bales of cotton?

A masonry heater (or masonry stove, ceramic stove, tile stove) is a device for warming an interior space through radiant heating, by capturing the heat from periodic burning of fuel (usually wood), and then radiating the heat at a fairly constant temperature for a long period .  The technology has existed in different forms, from back into the Neoglacial and Neolithic periods.  Archeological digs have revealed excavations of ancient inhabitants utilizing hot smoke from fires in their subterranean dwellings, to radiate into the living spaces.  These early forms have evolved into modern systems.  Evidence found from 5,000 B.C. of massive blocks of masonry used to retain heat foreshadowed early forms of fire hearths that were used as multifunctional heating sources.  Later evolutions came in the Roman "hypocaust", Austrian/German ("kachelofen", baths) using the smoke and exhaust of a single fire.  In Eastern and Northern Europe and North Asia, these kachelofens (or "steinofens") evolved in many different forms and names: for example the Russian Stove/Fireplace (Russian: ), the Finnish Stove (in Finnish: "pystyuuni" or "kaakeliuuni", "tile oven") and the Swedish Stove (in Swedish: "kakelugn", "tile stove" or "contra-flow stove") associated with Carl Johan Cronstedt.  The Chinese developed the same principle into their Kang bed-stove.  The masonry heater has gained renewed domestic popularity recently because of its heating efficiency. <SEP> A smokebox is one of the major basic parts of a steam locomotive exhaust system.  Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler.  The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel).  Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two main reasons.  Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox.  Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day.  Without a smokebox, all char must pass up the chimney or will collect in the tubes and flues themselves, gradually blocking them. <SEP>  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. A chimney is a structure that provides ventilation for hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere.  The space inside a chimney is called a "flue".  Chimneys may be found in buildings, steam locomotives and ships.  In the United States, the term smokestack (colloquially, stack) is also used when referring to locomotive chimneys or ship chimneys, and the term funnel can also be used. <SEP>  Commissioned by industrialist Cornelius Vanderbilt, the ship was considered one of the most luxurious steamers in operation, and began service on a route between New York City and Providence, Rhode Island.  In 1837, the "Lexington" switched to the route between New York and Stonington, Connecticut, the terminus of the newly built railroad from Boston.  Vanderbilt sold the ship to his competitor, the New Jersey Steamship Navigation and Transportation Company, in December 1838 for $60,000, at which time the "Lexington" was reputedly the fastest steamer on Long Island Sound.  On the night of 13 January 1840, midway through the ship's voyage, the casing around the ship's smokestack caught fire, igniting nearly 150 bales of cotton that were stored nearby.  The resultant fire was impossible to be extinguished, and necessitated the evacuation of the ship.  The ships' overcrowded lifeboats were sunk almost immediately after their launch, leaving almost all of the ship's passengers and crew to drown in the freezing water, with rescue attempts impossible due to the rough water and lack of visibility. The Lexington was a paddlewheel steamboat that operated along the Atlantic coast of the Northeastern United States between 1835 and 1840, before sinking in January 1840 due to an onboard fire.  Of the estimated 143 people on board the "Lexington", only four survived, having clung to large bales of cotton which had been thrown overboard.
