Gas Fire
A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane or butane. Indoor household gas heaters can be broadly categorized in one of two ways: ''flued'' or ''non-flued,'' or ''vented'' and ''unvented''. History The first gas heater made use of the same principles of the Bunsen burner invented in the previous year. It was first commercialized by the English company ''Pettit and Smith'' in 1856. The flame heats the air locally. This heated air then spreads by convection, thus heating the whole room. Today the same principle applies with outdoor patio heaters or "mushroom heaters" which act as giant Bunsen burners. Beginning in 1881, the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, a British engineer. Later, fire clay replaced the asbestos because it is easier to mould. Modern gas heaters still work this way although using other refractory material. Moder ...

Gas Heater 1970s
Gas is one of the four fundamental state of matter, states of matter (the others being solid, liquid, and plasma (physics), plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), chemical element, elemental molecules made from one type of atom (e.g. oxygen), or chemical compound, compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as Earth's atmosphere, air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas Particle, particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are c ...

Outdoor Heating
Outdoor heating is space heating that allows people to stay in substantially unenclosed spaces that would otherwise be too cold for comfort. To this end, various outdoor heating appliances are available, including gas patio heaters, quartz or ceramic electric lamps, and wood burning chimenea and fire pits. In an outdoor environment, convection would quickly carry away heat in the form of hot air, so all these methods emit various amounts of their total output as radiant heat Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is .... Radiant heat is emitted from the appliance, and is absorbed by objects and people, raising their temperature. References {{energy-stub Heating ...

Burners
Burning Man is an event focused on community, art, self-expression, and self-reliance held annually in the western United States. The name of the event comes from its culminating ceremony: the symbolic burning of a large wooden effigy, referred to as the Man, that occurs on the penultimate night of Burning Man, which is the Saturday evening before Labor Day. The event has been located since 1991 at Black Rock City in northwestern Nevada, a temporary city erected in the Black Rock Desert about north-northeast of Reno. As outlined by Burning Man co-founder Larry Harvey in 2004, the event is guided by ten principles: radical inclusion, gifting, decommodification, radical self-reliance, radical self-expression, communal effort, civic responsibility, leaving no trace, participation, and immediacy. The event originated on June 22, 1986, on Baker Beach in San Francisco as a small function organized by Larry Harvey and Jerry James, the builders of the first Man. It has since bee ...

Fireplace
A fireplace or hearth is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design. Historically, they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or fire pit; a chimney or other flue allows exhaust gas to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantel, a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, an overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner. On the exterior, there is often a corbelled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kerosene Heater
A kerosene heater, also known as a paraffin heater, is typically a portable, unvented, kerosene-fueled, space (i.e., convectional) heating device. In Japan and other countries, they are a primary source of home heat. In the United States and Australia, they are a supplemental heat or a source of emergency heat during a power outage. Most kerosene heaters produce between . Operation A kerosene heater operates much like a large kerosene lamp. A circular wick made from fiberglass and/or cotton is integrated into a burner unit mounted above a font (tank) filled with 1-K kerosene. The wick draws kerosene from the tank via capillary action. Once lit, the wick heats the Kerosene until it turns into a gas (gasification) and this gas is then burnt which heats air via convection or nearby objects via radiation. The burner is designed to properly oxygenate and distribute the flames. The flame height is controlled by raising or lowering the exposed wick height inside the burner uni ...

Gasoline Heater
A gasoline heater is a small gasoline-fueled space-heater. Fixed versions were originally used mainly for supplemental heat for passenger compartments of automobiles and aircraft, with the latter still in production. Portable versions were also made. Gasoline heaters were commercially available on automobiles starting in the 1930s with continued use until the 1960s, when they were almost entirely replaced with heaters that blow air past a small radiator warmed by hot engine coolant. Operation Gasoline is brought to the heater from the vehicle’s fuel system. A fan blows air into a combustion chamber, where a glow plug or similar ignition device lights the gasoline/air mixture. Ducting around this contains a second fan, which blows air warmed by contact with the combustion chamber into the interior of the vehicle. Electricity is required to heat the ignition source, with systems designed to be compatible with 6-volt, 12-volt, and 24-volt automotive and aircraft electrical ...

Radiator
Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for automotive engine cooling and HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason developed a primitive radiator in 1841 and received a number of U.S. patents for hot water and steam heating. ...

Pilot Light
Merker Tankless water heating, tankless gas-fired water heater from the 1930s, with pilot light clearly visible through the aperture in the front cover. The large opening allowed for the manual lighting of the pilot light by a lit match or taper A pilot light is a small Fuel gas, gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition source is necessary, as in when lighting a large burner. A United States patent was filed May 13, 1922 for a "safety gas-control system" by two employees of the Newark, NJ-based Public Service Gas Company, Conrad Shuck, Jr. and George Layer. The term "pilot light" is also used occasionally for an electrical indicator light that illuminates to show that electrical power is available, or that ...

Thermostat
A thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint. Thermostats are used in any device or system that heats or cools to a setpoint temperature. Examples include building heating, central heating, air conditioners, HVAC systems, water heaters, as well as kitchen equipment including ovens and refrigerators and medical and scientific incubators. In scientific literature, these devices are often broadly classified as thermostatically controlled loads (TCLs). Thermostatically controlled loads comprise roughly 50% of the overall electricity demand in the United States. A thermostat operates as a "closed loop" control device, as it seeks to reduce the error between the desired and measured temperatures. Sometimes a thermostat combines both the sensing and control action elements of a controlled system, such as in an automotive thermostat. T ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.
