Physics:Bio fireplace
A bio fireplace (also on bio-ethanol fireplace, ethanol fireplace) is a type of fireplace or furnace with combined zones generation of heat and technological process – combustion of fuel (denatured alcohol). This fireplace can be installed without a chimney and gives the real flame, not imitation. The main part of each bio fireplace is the burner. The burner is a metal container with various shape and dimensions. The burner is filled with fuel, usually it is bioethanol. Fuel is poured into the burner and lit with an extended candle lighter as suggested. Bio fireplaces should be operated with care, since bioethanol is highly flammable.[1][2][3] Severe burn accidents can happen.[1][4] Bioethanol-fueled decorative fireplaces are dangerous even by intended use.[5] Gases from combustion, like carbon dioxide and nitrogen dioxide, volatile organic compounds, and particulate emissions are released into the room.[6] Bio fireplace - irrespective of the type of fuel used are a source of fine and ultrafine particles and have a considerable influence on the quality of the indoor air if ventilation is not provided.[6] It may generate odors.[7]
Types
Ethanol fireplaces are available in several different designs.There are manual ethanol fireplaces and automatic ethanol fireplaces. Automatic ethanol fireplace flames have no direct contact with fuel. Fuel is in stored in a reservoir and then heated until the alcohol vapors evaporate into the burner. These vapors are then ignited by a spark system in the unit. User can turn the flames on or off as well as regulate the flame size with a remote control, mobile app or smart home system. A microprocessor controls burning process, using numerous sensors to keep burning parameters stable. If the sensors detect any issues- such as an earth quake, low oxygen or excessively high temperatures- they will extinguish the flame. Wall mounted designs can be built into a drywall wall or be recessed into the wall. Free standing or stand alone ethanol fireplaces are portable, and can be used in any architectural setting. Table top ethanol fireplaces are the smallest versions of ethanol fireplaces and are often used as a decoration.
