Catalytic Heater
A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce califaction (heat). When the catalyst, natural gas, and oxygen combine together they ignite at a low enough temperatures that a flame is not needed. This process keeps repeating itself until either oxygen or the fuel source is taken out of the equation. Types There are three main types of larger catalytic heaters: # Heated Enclosure Packages # Instrument Gas and Pilot Preheating Regulators # Space Heating Heated enclosure packages are used to protect pipes from rain and ice build-up by keeping the pipes heated. The catalytic heater is contained within the package which is usually made out of stainless-steel. Instrument gas and pilot preheating regulators are only used for freeze protection, and to heat up the gas before it reaches the pilot. It can also be used to heat a stream of gas that's used for measurement or instrumentation. Space heating is a good su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heater
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Space Heater
A space heater is a device used to heat a single, small to medium sized area. Operation Electric space heaters fall into four main categories: fan heaters, ceramic, infrared, and oil-filled. * Fan heaters are the cheapest, but are often the least efficient and versatile. Nonetheless, they can be useful for heating small spaces, such as a small room or office cubicle. * Ceramic heaters push air across a piece of heated ceramic material. They can adequately heat a typical bedroom. * Infrared heaters provide more heat than ceramic models, and are also smaller and quieter. They do not oscillate like ceramic heaters, but consist of a heating chamber deep within the unit that prevent accidental fires, and allows for greater accumulation of heat before it is emitted by the unit. By the mid-2010s, many were outfitted with touch-screen controls and energy-saving settings, and were styled in such a way to complement the user's furniture. They grew in popularity in the 2010s. * Oi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flammable
A combustible material is something that can burn (i.e., ''combust'') in air. A combustible material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame. The degree of flammability or combustibility in air depends largely upon the volatility of the material - this is related to its composition-specific vapour pressure, which is temperature dependent. The quantity of vapour produced can be enhanced by increasing the surface area of the material forming a mist or dust. Take wood as an example. Finely divided wood dust can undergo explosive combustion and produce a blast wave. A piece of paper (made from wood) catches on fire quite easily. A heavy oak desk is much harder to ignite, even though the wood fibre is the same in all three materials. Common sense (and indeed scientific consensus until the mid-1700s) would seem to suggest that ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon Monoxide Poisoning
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. The classically described "cherry red skin" rarely occurs. Long-term complications may include chronic fatigue, trouble with memory, and movement problems. CO is a colorless and odorless gas which is initially non-irritating. It is produced during incomplete burning of organic matter. This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (HbCO) preventing the blood from carrying oxygen and expelling carbon dioxide as carbaminohemoglobin. Additionally, many other hemoproteins such as myoglobin, Cytochrome P450, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naphtha
Naphtha ( or ) is a flammable liquid hydrocarbon mixture. Mixtures labelled ''naphtha'' have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions ''naphtha'' may also be crude oil or refined products such as kerosene. ''Nephi'' and ''naphthar'' are sometimes used as synonyms. It is also known as Shellite in Australia. Etymology The word ''naphtha'' is from Latin and Ancient Greek (νάφθα), derived from Middle Persian ''naft'' ("wet", "naphtha"), the latter meaning of which was an assimilation from the Akkadian ''napṭu'' (see Semitic relatives such as Arabic ''nafṭ'' petroleum" Syriac ܢܰܦܬܳܐ ''naftā'') and Hebrew נֵפְט ''neft'' (meaning petroleum). In Ancient Greek, it was used to refer to any sort of petroleum or pitch. There is a hypothesis that the word is connected with the name of the Indo-Iranian god Apam Napat, which occurs in Vedic and in Avestic; ...

Butane
Butane () or ''n''-butane is an alkane with the formula C4H10. Butane is a gas at room temperature and atmospheric pressure. Butane is a highly flammable, colorless, easily liquefied gas that quickly vaporizes at room temperature. The name butane comes from the root but- (from butyric acid, named after the Greek word for butter) and the suffix -ane. It was discovered by the chemist Dr. Walter Snelling in 1912. It was found dissolved in crude petroleum in 1864 by Edmund Ronalds, who was the first to describe its properties. Butane is one of a group of liquefied petroleum gases (LP gases). The others include propane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Butane burns more cleanly than gasoline and coal. Density The density of butane is highly dependent on temperature and pressure in the reservoir. For example, the density of liquid phase is 571.8±1 kg/m3 (for pressures up to 2MPa and temperature 27±0.2 °C), while the density of liq ...

Soldering Iron
A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces. A soldering iron is composed of a heated metal tip (the ''bit'') and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons, less commonly used today than in the past, were simply a large copper ''bit'' on a handle, heated in a flame. Solder melts at approximately . Soldering irons are designed to reach a temperature range of . Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods.Bralla, James G. ''Handbook of Manufacturing Processes - How Products, Com ...

Compressor Station
A compressor station is a facility which helps the transportation process of natural gas from one location to another. Natural gas, while being transported through a gas pipeline, needs to be periodically pressurized at intervals of . Siting is dependent on terrain, and the number of gas wells in the vicinity. Frequent elevation changes and a greater number of gas wells will require more compressor stations. The compressor station, also called a pumping station, is the "engine" that powers a long-distance natural gas pipeline. As the name implies, the station compresses the gas (increasing its pressure) thereby providing energy to move it through the pipeline. The compressor is driven by a motor fueled by some of the natural gas bled from the pipeline. Pipeline companies install compressor stations along a pipeline route. The size of the station and the number of compressors (pumps) varies, based on the diameter of the pipe and the volume of gas to be moved. Nevertheless, the b ...

Wellhead
A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment. The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment. While drilling the oil well, surface pressure control is provided by a blowout preventer (BOP). If the pressure is not contained during drilling operations by the column of drilling fluid, casings, wellhead, and BOP, a well blowout could occur. When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production. Wellheads are typically welded on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
